The Mac is back and more Pro than ever, throwing away the cylindrical “trash can” design in favor of something that resembles a computer. Its appearance may harken to the original Mac Pro from 2006, but can it compare in the repairability department? We dropped six thousand dollars and one block of hard cheddar to find out. Let’s tear it down.

  1. It may not be the expensive configuration handed out to so many YouTubers, but our base model Mac Pro will still put a dent in your titanium Apple Card wallet at a cool six grand, offering: 8-core Intel Xeon with 24.5 MB of L3 cache and a 4.0 GHz max turbo frequency 32 GB (four 8 GB modules) of 2666 MHz DDR4 ECC Memory
    • It may not be the expensive configuration handed out to so many YouTubers, but our base model Mac Pro will still put a dent in your titanium Apple Card wallet at a cool six grand, offering:

    • 8-core Intel Xeon with 24.5 MB of L3 cache and a 4.0 GHz max turbo frequency

    • 32 GB (four 8 GB modules) of 2666 MHz DDR4 ECC Memory

    • AMD Radeon Pro 580X with 8 GB of GDDR5 VRAM

    • 256 GB PCIe-based flash storage module

    • 802.11ac Wi-Fi wireless networking and Bluetooth 5.0 wireless technology

    • Like the Mac Pro before it, this one is also "Assembled in USA" at a plant in Texas. They say everything's bigger in Texas, and this new Mac Pro is no exception.

    • Unlike the old Mac Pro, this one has a new model number: A1991, and EMC 3203.

  2. From the side, the Mac Pro is about as Apple as they come. Huge, honkin' Apple logo? Check. Cold, hard stainless steel? Check. Precisely milled aluminum slabs? Check. Around back, we spot some ports: a 3.5 mm audio jack, two Thunderbolt/USB-C ports, two USB-As, two HDMIs, two 10 Gb Ethernets, and a run-of-the-mill C14 power plug. Ports are cool, but we're more excited about what's behind all that black plastic: eight PCIe slots, which add up to more upgradability than we've  seen from any Apple product in a long time.

    • From above, you can spot two more USB-Cs and what looks like an inconspicuous power LED to the left of the power button.

    • We already got a look at the Mac Pro's two primary handles, but what's this third one up top?

    • Maybe it opens the computer? Nah, it can't be that easy.

  3. Before we tear down, we ask our friends at Creative Electron to stuff our Mac Pro into their X-ray machine. Unsurprisingly, this thing is so big that it wouldn't completely fit into the X-ray cabinet—but so far, it's looking a lot like a tower PC.

    • That's good news, everyone.

    • Despite its cheese-grater appearance, this new Mac Pro cannot grate cheese. This important consumer advice is brought to you by iFixit, the company that wonders: why doesn't anybody send us review units?

    • We cleaned and de-cheesified the outer casing (quite easily with a halberd spudger) before putting it back on the computer. So don't worry—it smells fine.

    • Time to open the case. We came to this teardown armed with many tools, but so far all we need is our fingers.

    • Some informative dots tell us this handle rotates, and with surprising ease.

    • Like Johann Schmidt delicately handling the Tesseract, a twist and pull on this third handle uncovers everything hiding beneath.

    I’m curious how the cover slides past the four handle rails. Does it touch/scratch as it slides by?

    As Peter Paul Chato pointed out in his “fevered dream” update on YouTube, it is too bad that Apple decided to engineer the top cover to not be removable without removing ALL the rear cabling. Would have been nice to have seen some genius feat of structural engineering, like putting a structural wishbone in there, to make it so you could remove the cover without necessitating disturbing the cabling.

    Also of note that the pictures released thus far of the rack-mount Mac Pro don’t show any change to the back panel, and no cable management arm to be seen.

    Scott - Ответить

    Maybe it’s a feature. They always tell you to unplug everything before you go snooping inside to install something. Now you have to.

    Well, maybe only the power plug needs to be unplugged. They could have made it so only the power cord would obstruct opening the case. The top ports need to be disconnected at least.

  5. Unfazed by the ominous array of black modules in the case, we pull the first switch we can find, and... Voilà! Up pops the first memory cover, revealing two out of the four sticks of RAM that came with our base configuration model. (There's room for eight more sticks in there.) Still no tools required for any of this—if you have opposable thumbs, you can replace this RAM (we even have some!). Somebody pinch us.

  7. The feet are held in place with just one screw each—although the screws themselves are buried deep in slots in the space frame pillars, making them a bit awkward to access. We make do with a 4 mm hex key and a Mako driver for extra leverage. The screws are held captive inside the frame, so you won't lose those, but we can't say the same for these feet. Better keep an eye on these things so they don't run away. We didn't shell out the $400 for the wheel-y upgrade, so it's nice to know that we don't really need to drag this thing to the Apple store to swap its shoes.

    • If you're feeling adventurous and want to attach your own feet or wheels, the screws are M5x0.8. Since we can't remove them, we're unsure of their exact length, but we estimate 15-20 mm. They extend out about 4-4.5 mm from the bottom of the aluminum slab.

    Really would like to see how the wheels are attached/removed, and if the wheels can be locked from rotating.

    • The I/O boards are held in place by Phillips head thumbscrews and can be loosened (and tightened) by hand. But our trusty Manta Driver Kit is always here to assist.

    • All PCIe cards are locked in place by a single switch (handily labeled as step 2).

    • This switch moves a rail with little hooks on it that secure anything in their path. In other words: one switch to remove them all, one switch to bind them.

    • And we gotta say, it's a really nice feeling switch.

    Any chance shots of the I/O card and PSU are forthcoming?

    repoman27 - Ответить

    I could see a TPS51980A on the I/O card but I could not see the Thunderbolt controller (probably a JHL7540 like for the top ports). The I/O part of the card appears to have 44x2 pins which is enough for two DisplayPort inputs (≈20 pins each) and two USB 3.1 gen 2 inputs (≈9 pins each) plus some other connections (Thunderbolt header (sleep signals, force power, plug even, like on a PC motherboard)? audio (because all the PCIe lanes are used by the Thunderbolt controller so there’s none left for an audio controller?).

    Hey Barry,

    @ryanwgregg helpfully provided this link showing a user’s experience with the J2i. From the looks of it, the drive cage clicks onto various standoff posts. The included cables attach directly from the drive ports to the data and power connectors.

    Arthur Shi -

    For the I/O part of the card, I forgot to say that there may exist two USB 2.0 connections (≈ 2 pins each) because Titan Ridge in other Macs use USB 2.0 from the chipset to provide support for USB 2.0 devices connected to the Thunderbolt ports. I wonder if the I/O connector also includes serial lines from the UARTs?

    Joseph van Tunen - Ответить

    So now you have me thinking, the C621 PCH only provides 14 USB 2.0 ports, and by my count:

    2 for the Thunderbolt 3 ports on the top of the case

    1 for the internal USB 3.0 Type-A port

    2 for the Thunderbolt 3 ports on the Apple I/O card

    2 for the USB 3.0 Type-A ports on the Apple I/O card

    4 for MPX slot 1 (up to 4 Thunderbolt 3 ports)

    4 for MPX slot 2 (up to 4 Thunderbolt 3 ports)

    Which is one too many for the PCH, so there must be a hub or additional USB 2.0 EHCI somewhere to make that work.

    I did spy a pair of TI TUSB1002A USB 3.2 10 Gbit/s dual-channel linear redrivers on the I/O card, which would be for the USB 3.0 signals routed from the PCH to the USB Type-A ports via the proprietary portion of the I/O card connector. There’s also the JHL7540, a pair of TI CD3217B or similar USB PD/Type-C port controllers, and possibly a Cirrus Logic CS42L83 audio codec on the card, but you can’t make out any of the part numbers. The audio codec probably needs a couple S2I connections to the T2 chip.

    repoman27 -

    Do we know for sure that Titan Ridge in host mode can’t provide its own USB 2.0? I have a Titan Ridge Thunderbolt dock with Titan Ridge USB controller that supports USB 2.0. Maybe that’s a feature of the JHL7440 that doesn’t exist in the JHL7540. Actually, I don’t know what chip it uses because I can’t open it and the pci ids database calls all Titan Ridge chips JHL7540…

    Joseph van Tunen -

    The decision not to include an EHCI in Thunderbolt 3 host controllers is slightly baffling to me, but does make a modicum of sense at least in the host context. I’ve yet to determine whether the JHL7440 includes one, but if it doesn’t, then it’s a pretty ridiculous thing to leave out. You should be able to look at the USB Device Tree in System Information with a USB 2.0 device plugged into the various ports and see how it’s listed. For instance, If I connect a USB 2.0 device to the Thunderbolt 3 port of my MacBook Pro, it shows up under AppleUSBXHCISPT, which would be the Sunrise Point PCH, vs. AppleUSBXHCIAR for Alpine Ridge or AppleUSBXHCIFL1100 for Fresco Logic FL1100. There are very few two-port Titan Ridge devices in the wild where the second Thunderbolt port is actually exposed, and it may be partly due to the shenanigans involved in properly supporting USB protocols on that second port.

    repoman27 -

    Yes, the driver for the USB 2.0 port on my Titan Ridge dock is AppleUSBXHCITR. TR = Titan Ridge.

    The Titan Ridge is different than Alpine Ridge because it has a USB output that is separate from the two Thunderbolt outputs. The downstream Thunderbolt port can be used for USB (port 1 for USB 2.0, port 3 for USB 3.x), DisplayPort, or Thunderbolt. The USB output of the Titan Ridge is just for USB (port 2 for USB 2.0 and port 4 for USB 3.x). I have tested a USB 2.0 mouse and a USB 3.x flash drive.

    The Blackmagic eGPU is similar to my dock but it uses a JHL7540 so maybe all Titan Ridge chips have the separate USB output. So what makes the JHL7440 special is that it can accept USB-C with DisplayPort alt mode as input through a Thunderbolt port. And so there don’t appear to be any shenanigans required for USB on Titan Ridge in peripheral mode.

    As far as I know, You can only use both USB ports of Alpine Ridge when it is in host mode which has both Thunderbolt ports as downstream.

    Joseph van Tunen -

    Upon further consideration, I’m pretty sure USB 2.0 never touches the Thunderbolt controllers. In a host setup, the signals are routed from the PCH to each Thunderbolt port controller. In 2-port device configurations, USB 2.0 is routed directly from the upstream port controller to the downstream port controller, unless the design requires USB 2.0 for some reason, in which case it’s routed to the upstream facing port of a hub instead.

    As for JHL7440 support for USB3 hosts, the simplest way to achieve this logically is for the downstream Thunderbolt and dedicated USB ports to be connected to the downstream facing ports of a hub, with the upstream facing port of the hub connected to a 2:1 mux which can switch between the upstream Thunderbolt port and the integrated xHCI depending on the capabilities of the attached host. There is probably only a single stepping of Titan Ridge silicon, but for obvious reasons, that mux would have to be either fused off or fixed in firmware for host implementations.

  8. It's raining modules! The I/O board, video card, and power supply all come out from the same side of the case. We stop for a moment to admire all the numbers indicating the order of operations. Labels are great for repairability! (Believe it or not, not everyone reads the repair manual.) The power supply is the last easily-removable module to come out. It's held in place with a single T8 Torx screw.

    I wonder what the possibility would be to get an additional i/o board. I need 3 thunderbolt 3 ports for my set up, but i’m reluctant to use the top ones (just bad style).

    Dave Kimura - Ответить

    Agreed. But the only way I can determine, so far, to add actual Thunderbolt 3 ports is to upgrade the video card for $2400-$5200 (W5700X pricing TBD), each of the upgrades including four more Thunderbolt 3 ports, each.

    I’m stuck in the same boat; with just the 580X, I would burn all four base ports attaching my peripherals, with no room to grow, save for expensive, flakey pass-through hubs I don’t otherwise need.

    there’s been some limited success getting the $100 Gigabyte Titan Ridge Working on cMP, and they definitely work on certain Hackintosh, but MP 2019 doesn’t have the stated required TBC board headers, and so far I can’t find anyone who’s even tried it to see if the TB headers are irrelevant, and effectively present and wired directly on the actual PCIe slot, not just the MPX; I’m planning on trying it, but I’m pretty certain it’s the latter, and it’s not going to work.

    frederico -

    it’s not out of the question for someone to build a TB3 card for the 7,1, but it ain’t gonna come in at $100, that’s for sure. Not being able to justify the need for the Vega card , or unless the W5700 comes in much cheaper than I’m predicting at around $1400, I’m going to be installing aftermarket video to free up the two top ports for come and go devices.

    frederico -

    And the real kicker is the Apple I/O Card will only work in Slot 8.

  9. Teardown Update: Let's take a closer look at this custom AMD Radeon Pro 580X video card module: When you pull the release latch, it engages two rollers on the opposite side, which simultaneously undock the card and push it away from the mothership motherboard. Unlike the module itself, the silicon inside does not come out with a clever lever! A few sneaky screws are hidden under a giant sticker atop the cooling fins, and then we have to carefully disengage the lever mechanism before we can finally pull out the card.

    • For our efforts, we are rewarded with the following:

    • The main event! AMD's Radeon Pro 580X, (an iteration of their Pro 500 series for Macs) built on their 14 nm Polaris architecture, featuring 36 compute units.

    • Two rows of Micron GDDR5 VRAM, totaling 8 GB

    • 2x MegaChips MCDP2920, likely something akin to their MCDP2900 DisplayPort 1.4 to HDMI 2.0 converter

    • International Rectifier IR35217 buck controller (similar to the IR35211) and NXP's L6524 I/0 expander

    The pictures show the four 4 lane DisplayPort 1.4 connections are at the end of the MPX slot away from the MPX power pin. So the unused pins near the MPX power pin are probably for the two 4 lane PCIe connections for the two Titan Ridge Thunderbolt controllers that the Radeon Pro 580X doesn’t have (and probably four USB 2.0 connections if Titan Ridge doesn’t support USB 2.0 itself).

    It’s worth noting for anybody unaware: this is not exactly an SSD. It’s a card with flash chips and a buffer, but no controller. The controller is the T2, which is on the logic board.

    This makes aftermarket storage easier to manufacture (no need to source a controller or the firmware for it), but due to the limited market, I wouldn’t expect to see anybody but Apple make these modules.

    After going through really frustrated conversation with Apple tech support yesterday, and with this article, I would recommend not to DIY any T2-related part. Apple is not exactly being friendly to disclose further guidance for user to replace these parts. In fact even expert like OWC couldn’t crack down enough to provide compatible parts on iMac Pro.

    With all the friendliness swapping out parts, this is an area you don’t want to get your hands wet.

    With a machine of this calibre, why Apple did you not go with an industry standard NVMe slot instead? I’m sure there would be some relatively straightforward way to keep the T2 crypto engine and still use NVMe storage.

    At least Apple’s pricing for SSD storage isn’t insane, however with NVMe slots, we could use a Samsung 970 Pro and add 1 TB of storage for $300 instead of $400.

    Steve Wechsler - Ответить

    The SSDs are encrypted by the T2 and therefore have added security. I guess the T2 is acting as the NVMe controller? I haven’t seen pictures of the modules that show if they have a controller or not.

    The base configuration comes with only one SSD module. If you have a configuration with two modules, are they hardware RAIDed together? Apple does not say either way. A RAID would require 8 PCIe lanes instead of 4 so probably not.

    macOS doesn’t allow booting from software RAID of normal SSDs (without some setup difficulty).

  11. The three-fan array comes out in one piece. It's held in place with six screws and connects to the logic board with spring contacts—no fussy cables to deal with!

    • Most tower computers have dedicated fans for the CPU and GPU in addition to fans at the front & rear of the case. The Mac Pro just has front and rear fans, which supposedly provide enough cooling to keep it chill under stress.

    • Another thing most tower computers have: some sort of debris filter to get rid of particles in the air that the cooling fans pull in. Apple's engineers are on record saying they don't need that, but only time will tell how dusty these things get.

    No, the speaker is absolute garbage according to a video clip Snazzy Labs posted on Twitter.

    noah.lach -

    My guess is that they expect media professionals (the obvious target market) to be using their own audio interfaces, probably attached via USB or Thunderbolt.

    Which is perfectly understandable, since most people running a desktop system (who care about sound quality) typically use external speakers anyway. My home Mac (a 2012 mini and its predecessor, a 2002 PowerMac) is connected to a Klipsch ProMedia 2.1 system and I wouldn’t have it any other way. As far as I’m concerned, Apple could get rid of the built-in speaker altogether on their desktop systems.

    ryanwgregg - Ответить

    Hey ryanwgregg,

    We may do a teardown update on the WiFi/Bluetooth card.

    They definitely did some creative routing for the wireless cables! In order to get good wireless reception through the pretty solid aluminum enclosure, they routed the cables to the top of the case right underneath both handles. The antennas are covered by plastic inserts there, which allows the Mac Pro good reception.

    Arthur Shi -

    Arthur,

    Yes would really love to see a teardown update on the wireless / wifi card. I'm very into privacy and when receiving my mac pro would really want to disconnect and remove wifi / bluetooth as much as possible. With old macs the wireless card was removable. I understand here it's not, though it on a breakout board like this gives me hope, perhaps for some government customers or some special requirements labs they will release a version with a different breakout i/o top card without the wireless capabilities. In the meantime the first thing I'd do would be to disconnect these antennas which would at least significantly reduce the reception (curious as to how much), and I'd want to plan better to significantly via hardware disable that wireless chipset even if it means possibly some soldering. A better look at that setup would really help plan that out and decrease likelihood of breaking something.

    • Our base model may look a bit bare, but there's still plenty of silicon on this massive slab:

    • 2x aQuantia AQtion AQC107-B1-C multi-gigabit ethernet controller

    • 2x Diodes Incorporated PI3DBS16 PCIe Thunderbolt 3 signal mux

    • Pericom (acquired by Diodes Incorporated) P17C9X PCIe packet switch

    • TPS 51980A TI 921 A57R buck converter

    • PLX Technology PEX8798-AB80B1 G 1907 CB007158 TA1BAN, probably a PCIe switch

    • 3x Primarion (acquired by Infineon) PXE1610CDN, most likely PMIC

    The P17C9X is more likely a PI7C9X7952 PCI Express Dual UART I/O Bridge (supporting two 16C950 UARTs with baud rate up to 15 Mbps). Basically, serial ports. I don’t know what it would be for though. It should appear in IORegistryExplorer and lspci output because it’s a PCIe device.

    Joseph van Tunen - Ответить

    I second that motion. PI7C9X7952 all the way.

    repoman27 -

    Bluetooth module probably has a UART interface, but I can’t recall ever seeing this type of I/O bridge in previous Apple designs.

    repoman27 -

    The UARTs are between the two MPX slots, so maybe the MPX slots have UART lines for serial port communication?

    We could open a terminal, start talking, and see if anything responds.

    There are Bluetooth serial drivers so that could be it too. The serial driver is probably Apple16X50Serial.kext. Bluetooth UART driver is IOBluetoothHostControllerUARTTransport.kext. If the device is not matched by Bluetooth, then the normal serial driver will handle it probably.

    Joseph van Tunen -

    Where’s the PI3DBS16? I don’t see the orange square.

    Joseph van Tunen - Ответить

    The PEX8798 could be a PEX8796 (the picture is unclear). The number should match the PCIe product ID found in IORegistryExplorer or lspci output. Apple probably labels the slots in the I/O registry so it should be easy to discover how the 96 lanes are divided but you may need to populate each slot to be sure (the MPX part of a slot for the GPU Thunderbolt controllers might not be labeled?).

    Joseph van Tunen - Ответить

    It’s a Broadcom/Avago/PLX/whatever they’re calling themselves these days PEX 8796 96-lane, 24-port PCIe Gen3 switch. Pretty heavy-duty. They’re running it with dual upstream x16 links to the CPU, and the bandwidth allocation to the downstream ports is configurable via the Expansion Slot Utility.

    repoman27 -

    OWC has a much clearer picture of the PEX8796 in its 2019 Mac Pro teardown.

    Joseph van Tunen -

    Dual upstream? I’ve never seen that before. Are the slots divided between each upstream? I guess a single 96 takes less space and is less expensive than two 48. Does this have anything to do with the two pools of bandwidth configured in the PCI Expansion Utility - maybe we can see slots switch between upstream ports depending on whether pool A or pool B is selected? Wouldn’t that cause NVRAM variables saved per card to be wrong when the device path of the card changes? I guess it doesn’t matter - that is behavior that has to be handled in a normal Mac when PCI cards are changed around physically.

    Joseph van Tunen - Ответить

    The 8796 lets you create “two separate virtual hierarchies”, and I’m pretty sure that’s exactly what pool A and B are. I’d reckon a restart might be required after making any changes in that utility.

    repoman27 -

    I wonder if an x32 link would be superior to a dual x16? No matter, the 8796 only allows up to x16 links. I don’t know about the CPU…

    Joseph van Tunen -

    Xeon W=32xx CPUs have 64 PCIe lanes, 32 of which are connected to the 96-lane PEX8796. That leaves 32 lanes from the CPU, 64 lanes from the PEX8796, and 20 from the C621 PCH for downstream devices. Here’s my best guess as to the PCIe lane distribution:

    PEX x4 dual-port Thunderbolt 3 (Intel JHL7540)

    PCH x1 802.11ac Wi-Fi (Broadcom)

    PEX x4 PCIe slot 8 / Apple I/O card dual-port Thunderbolt 3 (Intel JHL7540)

    PEX x8 PCIe slot 7

    PEX x8 PCIe slot 6

    PEX x16 PCIe slot 5

    PEX x8 shared + x8 PCIe slot 4 (MPX bay 2, upper slot)

    PEX x8 shared MPX slot 2 (MPX bay 2, proprietary slot)

    CPU x16 PCIe slot 3 (MPX bay 2, lower slot)

    PEX x8 shared PCIe slot 2 (MPX bay 1, upper slot)

    PEX x8 shared MPX slot 1 (MPX bay 1, proprietary slot)

    CPU x16 PCIe slot 1 (MPX bay 1, lower slot)

    CPU 2x x16 96-lane PCIe 3.0 switch (Broadcom PEX8796)

    PCH x1 dual-UART (Pericom PI7C9X7952)

    PCH x4 T2 (Apple)

    PCH x4 NBASE-T 10GbE NIC 1 (Aquantia AQC107)

    PCH x4 NBASE-T 10GbE NIC 2 (Aquantia AQC107)

    6 remaining on the PCH for miscellaneous items?

    Joseph van Tunen - Ответить

    Yeah, but you only have a DMI 3.0 x4 uplink to the CPU, which is being oversubscribed to the tune of 2.7:1 or something like that. And the SSD controller in the T2 is perfectly capable of saturating that link all on its own.

    The MegaChips ICs (on the left side above the T2 chip, and on the right between the PCIe slots) are all marked MegaChips MCDP6100C1 1849A905ES. It’s possible they’re USB-C repeaters, like the MCDP6000.

    Thanks, Adam. I’d wager they’re serving as DisplayPort 1.4 retimers. And I can see now that there are 2x PI3DBS16412 on the other side of the board and 6x on this side.

    repoman27 -

    The components circled in dark blue need some revision. Working from right to left starting closest to the PCH you have a pair of 30-contact TQFN packages, then a pair of 40-contact TQFN packages, and finally eight 42-contact TQFN packages. All of them look to be from Diodes Inc. / Pericom, but none of them are the PI3PCIE2215 which you linked to and comes in a 28-contact package. They may all have part numbers that start with PI3PCIE, but they aren’t 2215s.

    Thanks for pointing that out, I updated the bullet with a corrected link.

    Adam O'Camb -

    Thanks again, Adam. Although that works for the two 30-contact chips, there’s still 10 more there (the next set of two and then the group of eight) that we don’t have part numbers for. And might I suggest linking to the manufacturer’s site rather than alldatasheet.com? Sorry to be such a pain!

    repoman27 -

    No problem at all! We don’t always have space in the teardown to list all the chips so I’m always happy to answer more specific questions. I also noticed I made a mistake with one of the model numbers which is corrected now. So the pair of 30-contact chips are 3242AZLE, the pair of 40-contact chips are 3442AZLE (added that to the last bullet), the four right 42-contact chips are P13WVR 13612ZLE Z1912GG, and the four left 42-contact chips are PI3DBS 16413ZHE 1907GG.

    Adam O'Camb -

    The P13WVR is probably PI3WVR13612 (the 1 is an I - the same mistake as for the PI7C9X7952 in the previous picture). I guess these are for switching the 8 DisplayPort connections of the two MPX slots between the four inputs of the two Thunderbolt controllers (top Thunderbolt controller and I/O card Thunderbolt controller). I don’t know what the circuit diagram would look like - if Apple doesn’t allow a lone MPX module in bay 2 then I think 6 DisplayPort switches would be required but if Apple allowed a 4 DisplayPort MPX module in bay 2 then 10 would be required. But there’s only 4?

    The PI3DBS16413 are used for PCIe? I don’t think they’d be used for Thunderbolt if the I/O card and GPUs have their own Thunderbolt controllers?

    I think we need pictures of the MPX modules, I/O card, and the top PCB.

    Joseph van Tunen -

    That whole cluster of components bounded by the coin-cell battery on the left, PCH on the right, and MPX slots on top and bottom are for DisplayPort switching. There are 2 MPX slots, each of which can provide 0, 2, or 4 DP sources which need to be routed to 2 Thunderbolt controllers, each with 2 DP sinks. The first two sources from each MPX slot go to the four PI3WVR13612 for a 1:2 demux, the latter two go to a pair of 2x2 matrix switches (PI3PCIE3442A for the main links and PI3PCIE3242A for the AUX channels). The 12 outputs are connected to the four 3:1 muxes (PI3DBS16413) with their outputs routed to the four MegaChips MCDP6100C1 DP 1.4 retimers and then on to the Thunderbolt controllers. I’d reckon the smaller components include four 3:1 single channel muxes for the AUX channels and four basic 3:1 muxes for the HPD lines. There should also be a couple 2x2 switches in there somewhere for the HPD lines.

    repoman27 -

    The PI3PCIE3242A and PI3PCIE3442A are 8 Gbps (PCIe gen 3). Are they good enough for DisplayPort 1.4 (8.1 Gbps)? They have applications for DisplayPort 1.2 (5.4 Gbps) and USB 3.0 (5 Gbps) but don’t mention DisplayPort 1.4.

    Also, what about muxes to switch PCIe lanes between the Thunderbolt controllers (two per MPX slot; x4 PCIe lanes per Thunderbolt controller) and the slots 2 and 4 ? Or are those PCIe lanes independent (which would be a waste of lanes)?

    Joseph van Tunen - Ответить

    I’m sure the signal integrity is just fine at 8.1 GT/s, but Apple is probably the only company crazy enough to use these parts for DisplayPort seeing as they really aren’t designed for it (no included AUX or HPD support). I guess discrete DP 2x2 matrix switches aren’t really a thing, so Apple just went with what was available off-the-shelf due to this being a relatively low-volume product.

    I posted my best estimation of the PCIe lane allocation in the comment thread for the other side of the logic board. Slots 2 and 4 both share 8 lanes from the PEX8796 with the proprietary side of the MPX slots by way of the 8 PI3DBS16412 muxes (6 on this side of the board, 2 on the other).

    repoman27 -

    8 of the PI3EQX8904 2-lane linear redrivers are being used to redrive the 16 PCIe Gen3 lanes routed from the CPU to PCIe Slot 1 at the bottom of the board, and the other 2 are redriving the 4 PCIe Gen3 lanes headed to the built-in Thunderbolt 3 controller at the top of the case.

    As well discussed already, and enumerated on Apple’s site, the USB 3.0 port is intended for software license dongles (for pros to better keep them from being easily stolen from an external port), but you are free to install anything you want that is USB-compatible; flash or SSD (with adapters), etc… As for the two SATA, also well-discussed that it (and the mini-10-pin power header) are currently filled with the optional Promise J2i dual-HDD carrier. You can expect more drive carrier options for far less money, and able to hold more drives. Already new owners are 3D-printing (and sharing) custom drive carriers.

    I will be building my own drive carrier from steel to host three 3.5” HDD and twelve 2.5” SSD and attached RAID card, which will migrate from my current MP. I might use the two included SATA ports for a couple spare SSD for clones or scratch; and I will probably run the USB3 port to a spare PCIe gate and make it available for external use.

    • Despite the many things to love, however, Apple still keeps the keys to certain repairs, like the proprietary SSD. And some of Apple’s repair manuals include (or entirely comprise) a disclaimer insisting that you contact an Apple Authorized Service Provider, when in reality the repair could easily be done at your desk.

    • With 2019 in our rearview, we’re starting to wonder: maybe Microsoft and Apple aren’t making devices more repairable just for fun (or for us)—maybe those Right to Repair bills are starting to look seriously scary?

@Gilmer Pelegrini, Jr - 9to5Mac only did RAM…CPU should be straight forward but good luck finding a W-3275M, W-3265M or W-3245(M).

ryanwgregg -

I’ve been wondering the same! Has it been confirmed that the Xeons from the Mac Pro are the W-32XXM series? I have a W-3175X and I’m curious if it would work. It still uses the Intel C621 chipset found on these boards.

TJM -

@TJM - The socket has the same number of pins, but the TDP of the W-3175X is 50 W higher and it only supports 48 PCIe lanes vs. 64 for the W-32xx SKUs. So I’m guessing that would probably be a no-go, mostly due to the TDP.

Absolutely not. Proprietary SSD that’s linked to the T2 security chip, so not only do you HAVE to buy the new SSD from Apple if you want/need to change it out, but you also have to have the repair done by an Apple technician because of the security chip. Should’ve lost multiple points for that. 7/10 would be a fair score.

Being that the W-3275 maxes out at 1TB of RAM, it can be assumed that Apple already uses the W-3275M to reach 1.5TB of RAM. One will need to test the 28-core with 256GB and 128GB RAM modules to verify that the Mac Pro (2019) supports 2TB on the W-3275M, W-3265M and W-3245M.

Does it accept exactly the same flash boards as the iMac Pro, or are these a new version?

What happens if you take a unit with the default 256 GB drive (as we see above, comprised of one board) and add another 256 GB board?

What if you take a unit with two boards and remove one board? At a minimum, it would require reformatting, since half the data would be gone, but does it work after formatting?

Can you run two boards of different capacities (256 GB and 512 GB, for example)? This can probably only be answered after the question about adding a second board to a unit which shipped with only one.

Zimmie -

The Mac Pro’s “SSD” can be changed, but they are not standard off-the-shelf M.2 SSDs. At a base level, off-the-shelf SSDs contain flash chips and a controller chip. The Mac Pro “SSD”s have memory chips but no controller—the T2 chip on the motherboard handles all that. The recent iMac Pro also use these controller-less SSDs. We plan to do some parts swapping and testing at some point!

Jeff S - Ответить

Hey Jeff!

Apple's primary options are the 32TB RAID MPX module, which would connect via PCIe. You can also purchase the internal storage enclosure (with 8TB hard drive), which allows you to mount two standard drives and connects to the internal SATA ports. Finally, you can use external drives.

Arthur Shi -

Has anyone given any thought to whether this could run a Type 1 hypervisor? That would then allow VMs running any OS, including Mac OS, to be run. The T2 allows only Mac OS or W10, which will rule out ESXi (and other linux-based hypervisors) from running on the default storage, but possibly would allow Hyper-V Server / Server core (if these use the same certificate as W10 - I don’t know)?

Alternately, boot drives connected to the SATA ports or a RAID card in one of the PCI slots (which would possible also allow ESXi, etc)?

Anyone investigated yet?

Thanks

But from repairability viewpoint this is bad because the standard parts (CPU and RAM) are the parts that are least likely to fail, whereas the parts that might fail (motherboard, power supply, etc) most are all proprietary and difficult or impossible to get.

Bob - Ответить

Can you elaborate more of the SSD’s being non-repairable? They look at a glance like regular m.2 drives, albeit with some kind of custom housing.

If the only issue is support for the T2 chip, you can disable boot restrictions by starting in recovery mode and using the Startup Security tool from utilities, which allows booting from external drives, so maybe this would do the same for non-Apple SSD modules?

Haravikk - Ответить

They provided a link to the iMac Pro teardown, where they describe the following: “Unlike a standard SSD, which has the controller logic onboard, these raw flash modules only have an interface buffer—the PCIe/NVMe controller lies elsewhere.” I believe the controller is part of the Apple T2 chip.

Gerard Pasman - Ответить

Two SSD modules in RAID?

Peter Gamble - Ответить

I’m expecting RAID-0, fast and efficient, but no redundancy.

Robert -

No, there are two slots for the proprietary modules that contain the NAND flash packages, but only one SSD controller (the T2 chip) located on the logic board. However, all SSDs use controllers that support multiple channels which can connect to multiple NAND packages containing multiple dies in order to leverage parallelism and increase performance. That’s one of the reasons they’re so dang fast.

There are four 8-pin and one 6-pin PCIe AUX power headers on the board to the left of the PCIe slots for use with non-MPX cards.

repoman27 -

You would need something like this, or third party alternative for 1/3 of the cost: https://www.apple.com/shop/product/HMUJ2...

The connectors look very standard so it shouldn’t cost much to make, but in typical Apple fashion the officially sanctioned kit’s price is set to unapologetically profitable level.

Doc Brown -

Can the 580X be installed in an external enclosure and used as an eGPU? Does it contain the second set of pins that the Vega II MPX module does or is it basically just standard pcie card in a fancy enclosure?

georgebrooksphoto - Ответить

Not without an adapter that no-one has invented yet. The second set of pins has four DisplayPort outputs from the 580X and it contains PCIe auxiliary power (takes the place of 6 pin or 8 pin power connectors). It seems like an adapter wouldn’t be too difficult to make to deliver power and extract the DisplayPort outputs (otherwise the card can only connect two HDMI 2.0 displays).

Those pins on the Vega II have only two DisplayPort outputs. They also have two PCIe 3.0 x4 links for the Thunderbolt controllers in the MPX module.

Those pins on the Vega II Duo are the same as with the Vega II but have four DisplayPort outputs like the 580X.

Joseph van Tunen -

Adrian Leung - Ответить

Probably. You may need to enable external booting if you want to boot from it.

Adrian Leung - Ответить

Probably. You just need to add power cables.

https://www.apple.com/shop/product/HMUJ2...

Your Thunderbolt ports won’t be able to connect a Thunderbolt display though. Not unless someone makes an adapter that can pipe up to four DisplayPort signals from the GPU into the extended MPX slot connector.

There is an MPX RAID module available from Promise.

And there are also 2 internal SATA 6Gb/s ports and what looks to be a Molex Micro-Fit 3.0, dual-row, 10-pin, vertical power header. Third party drive cages and cable kits are a little thin on the ground here at launch time (basically just the Promise Pegasus J2i), but I imagine iFixit, OWC, and other vendors will be all over it before too long.

Pick up a cheap internal 2 port PCIe SATA card, along with the two included internal SATA and get better (SATA III 6Gbps) top end speed than your existing cMP SATA II ports (assuming your drives saturate the bus), and roll your own drive cage or wait for less expensive third party solutions, or pay a crazy high price for the Promise 32TB RAID MPX module. plenty of good hardware RAID 0 cards for small change will let you stripe four or more HDD for even better speeds. Here’s the power connector you need for your own cable, if you can’t wait for third party makers. ( https://www.molex.com/molex/products/dat... )

Just because of that %#*@ T2 Chip this thing should have a 0 repair-ability score!

schietkop - Ответить

Surprised that you have it a 9/10 with the SSD being:

A. a proprietary design with few (or zero) third party options for purchase

B. Tied together with the T2 chip making user replacement impossible

jmdunk - Ответить

Better necessarily implies different. Apple sought to build a better SSD, and in many ways they did. If you don’t want to leverage the increased security, excellent performance, and higher capacity options that the T2 enables, you don’t have to use it. Buy the base 256 GB model and just treat it as a recovery drive. This box has 8 standard PCIe Gen3 slots, 2 standard SATA 6Gb/s ports, and an internal USB 3.0 Type-A port. You can use any bog standard M.2, HHHL PCIe, 2.5” or 3.5” SATA, or USB drive you like as an internal boot drive.

The T2 based SSDs provide an excellent user experience and have demonstrated high reliability. If you need to replace one or want to upgrade, you’ll need to contact Apple or an Apple Authorized Service Provider. There are 506 Apple store locations worldwide and more than 1800 AASPs in the US alone.

There’s valuing repairability, and then there’s prioritizing it above all else. I think iFixit’s assessment in this case was reasonably balanced.

repoman27 -

Welcome to the comment thread, to the apple employee who replied to me.

Honestly, you think quoting the number of Apple stores that exist in the US is a valid rebuttal to a clear example of anti-self-repair gatekeeping by Apple? Get lost with that. What are you even doing on this website?

A giant leap above the iMac Pro, which represents a monument to style over function — my iMP self-immolated after just over 18 months, with all the files on the SSD lost when the power supply blew, taking other components with it. Shameful for a >$5000 product. The new MacPro is reminiscent of its hefty predecessors — FIXABLE!!!

pwsloss - Ответить

What’s really driving me nuts here is storage. I need to add more SSD capacity beyond 4TB, it’s perfectly fine if it’s not secure/encrypted and, at the moment, there’s no clear path to doing that. I don’t want platters, other than for backup so they do not need to be an overpriced 7200rpm RAID. Yes there’s always external but given all the space within the unit, which is the purpose of the unit, that would be silly to have to resort to.

I presume this stuff will come, but the uncertainty of that has me nervous. Why should that need to be a third party kludge in the first place to get 8-10TB of SSD internal?

biomuse - Ответить

It’s not going to be that hard, just at this moment, choices are limited, but I fully expect commercial solutions will start arriving soon now that the whole of the aftermarket beyond Promise has access to the machine. If you’re desperate to add larger SSD storage now, you have several choices; the Promise J2i and R4i will provide power and standard 3.5” drive bays, wherein you can install 2.5” SSD with adapters. Next you can choose PCIe NVMe adapters/controllers, with 1 to 4 slots (starting at $20 and up to $500-$800; storage not included), allowing you to install way faster SSD storage than Apple is providing, for far less money. Or you can do what I’m going to do at first, which is to install my RocketRAID 840A (16ch SAS/SATA) and hang my 12 2.5” SSD on a homemade bracket in the upper bay where the J2i is meant to go, giving me 20TB of faster-than-OEM storage. Only other thing I have to do is add a 12v-5v adapter to power the drives, assuming I can’t just hack the existing 10-pin SATA power connector.

Ethan Zuo - Ответить

Is there any additional hard drive slots to add drives to this machine?

Michael Inman - Ответить

No. Hard drive slots would look ugly and some people don’t need them, so Apple left them out. The only two options currently are:

“Promise Pegasus R4i 32TB RAID MPX Module for Mac Pro”

“Promise Pegasus J2i 8TB Internal Storage Enclosure for Mac Pro”

You can buy a PCIe card to add NVMe drives.

Only the J2i has the Mac Pro SATA power cable that you would need for other SATA drives - or maybe you could combine one of the cables from the “Belkin AUX Power Cable Kit for Mac Pro” with some kind of 12V to SATA power adapter (12V 5V 3.3V) - or maybe the proprietary Mac Pro power connector for the SATA power cable has a standard connector and you can make your own cable?

Maybe other options will exist in the future for cables and drive bays.

Joseph van Tunen -

Here’s the connector you need to create a 12v/5v/3.3v power cable for SATA drives ( https://www.molex.com/molex/products/dat...); make your own drive cage or wait for the aftermarket to offer something more useful and less costly than the J2i. I’m building my own for twelve 2.5” SSD for an RR840A RAID 0 adapter..

Check the History (under Options, top right corner of the web page). Was information about Thunderbolt, WiFi, Bluetooth ever added? I don’t think so. It probably should have though.

There is a picture of the Thunderbolt controller for the top Thunderbolt ports. It’s clear enough to read the part number.

Joseph van Tunen -

After pulling out the motherboard, it looks like there’s a chassis board still in place (used for mounting the various components). Is that removable, leaving just the empty space frame (tubing, top, and bottom)? Perhaps you could add a couple pictures of what the final empty chassis looks like. If that chassis board is removable it’d be nice to have some pictures of it as well. (I’m looking towards the future. My suspicion is that if Apple respins various components, they’ll reuse the space frame, possibly with a different chassis board. And think of all the people who have repurposed old PowerMac or Mac Pro enclosures.)

You don’t do teardowns on desktops or tower PCs very often, but have there been any (other than the previous Mac Pro) with lower repairability ratings?

How to physically disable and get rid of Bluetooth an WiFi components?

Yahli Telem - Ответить

They seem to be located on the upper daughter board hosting the power ON/OFF relay and pogo pins; probably not going to be super easy to do much beyond disconnecting the antennae. Unfortunately, no one has yet posted an image of both sides of said card, so we just don’t know if the Broadcom chip is soldered or on an M.2-style adapter. However, there may be a special build SKU for government and corporate where WiFi/BT would not be allowed, so possibly one could swap out the whole daughter card for one sans those components.

frederico -

Could someone please verify that the extra four power headers on the main board (those intended to power video and other PCIe) are truly proprietary? The Belkin AUX Power cable images on the Apple Store aren’t super clear, but they look like standard eight pin locking connectors to me.

it irks me to pay $67 for $10 worth of everyday cables (notwithstanding most will go unused in a drawer).

Plenty of discussion that the SATA power header is a custom ten pin part (though it only uses eight contacts ( 4 by 4), and you have to buy an incredibly overpriced bracket and super noisy drive in a size you probably don’t want, just to obtain the $5 custom cable for pre-regulated SATA power.

frederico - Ответить

What does a non-proprietary 6 pin or 8 pin PCIe power connector look like? As for as I know, only the GPU end of the cable is non-proprietary. PSU manufacturers use different pinouts for the PSU end of the cable even if the connectors are the same. Even PSUs from the same manufacturer can have different pin outs for the PCIe power cables.

Joseph van Tunen -

That has not been my experience at all. MOBO headers and PSU 6 and 8 pin outputs are wired according to standards, just as are SATA/PATA/USB etc.. If a given PSU or MOBO manufacturer decided to swap pins around at the board level, when you installed a universal 8-8 or 8-6 or 6-8 connector, you could fry whatever component you attached it to.

e.g., this commonly available cable (an absolute ripoff at $12 because it lists as being specific to Mac Pro) is plug and play on *any* MOBO or PSU with standard 8 or mini-6 pin headers: ( https://www.amazon.com/COMeap-Express-Vi... )

frederico -

More typical is two for $8 (and most often even less than that): ( https://www.amazon.com/Cable-Matters-2-P... )

So, yeah, the Belkin pack is nicely black, probably the right length and of good quality, but if I only need one, I’m getting royally shafted.

frederico -

I’m not sure you’ve shown non-proprietary-ness yet.

First you linked a cable for a Power Mac or Mac Pro which is Apple specific. Maybe you want the 2019 Mac Pro to have connectors like the classic Mac Pro? But maybe the classic Mac Pro’s connectors were not enough for 8 pin PCIe power (150W each). Possibly the onboard 6 pin connector of the 2019 Mac Pro is the same as the classic Mac Pro.

Then you linked a PCIe extension cable which is only for extending PCIe power cables. Maybe you want the 2019 Mac Pro to have male PCIe power connectors on the motherboard instead of the female connectors.

Yes, it’s annoying that the Belkin package comes with cables you don’t need. But it’s like any modular PSU you might buy for a PC build.

Joseph van Tunen -

I linked to the Mac Pro mini-6-8 pin to prove a point that Mac-labeled parts are automatically overpriced. I’m sorry I linked to the second in a hurry and didn’t select the correct board-header option; they are in the same ballpark price. Generally you seem to be deliberately obstinate to the larger point that no one should have to pay $67 for two, let alone just one (usable) cable. It is no problem to find good quality 18/16g cables capable of over 300w, or you just build one if you buy the header connectors blank. If it matters to you, add black braid cable sheath for $0.50. If the connector on the MOBO isn’t proprietary, I promise you I won’t be paying $67 gouge tax to install a video card. But, hey, thanks for obfuscating the actual question with your opinion.

To that end, does anyone have a factual answer to my question? Are the PCIe headers on 2019 MP proprietary? Or do they accept any available molex header connectors for custom builds? I just need a good image of the headers (1/2, 3/4, 5/6), pls/thx!

frederico -

For anyone else playing along, if you look closely at the only image of the board-end of the Belkin cables, the fifth cable looks pretty much like a mini-6 to 6 (probably for MOBO header 5/6), & the other five look like a mini-8 to 6/8, which may or may not be proprietary. It won’t be impossible to hack whatever is required once pinouts are verified, but it would be nice to use standard parts.

frederico -

FWIW, hopefully it’s this brand new part number in the Molex MiniFit Jr. line: ( https://www.mouser.com/ProductDetail/Mol... ); the MiniFit 6 has been available for years. Even if the keys are different, they can be modified as long as the overall profile is correct. The voltage on the pinouts will be easy enough to verify once a fit is achieved.

frederico -

For those still playing along, OWC Kindly acknowledged a request for more details with a detailed image of the power headers (in the comments), along with other gorgeous component shots in the article itself) ( https://blog.macsales.com/57077-owc-tear... )

It’s looking very good for a simple install using the above-linked mini-8 Molex connector, so screw Belkin. I’ve ordered and will report here confirmation of a fit.

frederico -

Link spam robot denied my post confirming that the OWC teardown page and comment thread has images confirming it looks to be a mini-8 Molex connector on MOBO headers 1/2 & 3/4, and that the mini-6 Molex definitely fits header 5/6. Excellent news, so screw Belkin. I have ordered mine and will confirm fit here later.

frederico -

Would like to know which part on your website include all devices and the real cost of it.

Ayman El-Badry - Ответить

Can you link the correct board-header option?

I didn't say the connectors were proprietary. You can buy the connectors that will fit and make your own cable. I am saying that the connections to the connector (pin out or wiring) is proprietary. The only part that is not proprietary is the PCIe 6 pin or 8 pin (GPU) end of the cable.

hyatanasov - Ответить

It has 12V and 5V but no 3.3V. I don’t think there’s any way to know Watts except to load the system up until it stops. Hopefully it powers off before something melts. At least you shouldn’t exceed the amps allowed by the individual wires connected to the 10 pin connector.
