  1. MacBook Pro 15" Unibody Mid 2012 AirPort/Bluetooth Board Replacement, Lower Case: шаг 1, изображение 1 из 1
    • Remove the following ten screws securing the lower case to the upper case:

    • Three 13.5 mm (14.1 mm) Phillips screws.

    • Seven 3 mm Phillips screws.

    • When removing these screws, note how they come out at a slight angle. They must be reinstalled the same way.

    Step 1 (technically step 9 - replacing the base plate) Apparently one of my screws was a micron or two smaller than the others. This screw belongs to the hole above the optical drive, which is also apparently a couple of microns smaller than the others. It took seven attempts to figure which screw had originally been in that hole; all the other screws were too large, but fitted perfectly everywhere else.

    Bizarre much?

    It might be a matter of how the screws are driven in, and not that they're slightly different sizes. When I reassembled my MacBook, a couple of the screws, including the one over the optical drive you mention, were hard to drive in and jutted up a little bit instead of sitting entirely flush. Swapping screws didn't help. The solution was to unscrew them and drive them in at a bit of an angle - perpendicular to the slightly curved surface of the back plate where the screw holes were, instead of fully vertical with respect to the ground the Macbook is sitting on. Doing it that way, the screws were easier to drive in and they all ended up flush in their holes. Didn't matter which screws they were. (I swapped a few around just to check after reading this.)

    Andrew Janke -

    I had no such screw issues. Either there are differences in manufacturing lots or I just got incredibly lucky during reassembly!

    xtophr -

    I discovered a great way of organizing the screws. I used an ice cube tray and added the screws in order, keeping the different kinds together. So when it came to reversing the steps, the screw order was an added control step to returning everything in its place.

    Great advise! Love it! :)

    Ririds -

    I used to do that and that worked really great until I bumped it by accident and the entire tray went on the rug! I spent the next day sorting things out.

    Now I use these:


    The lower ones 50 to a package. I mark them w/ blue tape. Often if it's part like the fans, or the optical drive I'll tape the screws into/near the holes where they belong. I did this a lot especially w/ the bottom screws from MBPs until I'd done so many I knew exactly where the longer ones went.

    Richard Sato -

    I wrapped the screws in a piece of blue masking tape and wrote the number on the little pouch I made. Then I stuck the blue tape pouches on the underside of the case bottom in order.

    Roscoe -

    I take double-sided tape, put that on a piece of paper, stick the crews to that, and label them.

    jelimoore -

    Best I've found is a bead sorting tray. They're like $5 at Wal-Mart and they have a lid that seals up and won't let them jump between containers.

    maccentric -

    I take a sheet of paper, pierce the screws through the paper, take a pen and box the screws and write out what step they belong to.

    Nils -

    @Will, in my case I had the same result as you did. As a reminder to myself the next time I need to open the computer, I put a dot of white paint on those two screw's head and a very, very thin ring of white on the very edge of each hole, that way I'll know they go into those two holes.

    Roger - Ответить

    Actually the four screws on the bottom were not threaded all the way up. I didn't check to see if the thread gauge was the same on them, but it wasn't until I had about four screws out (I didn't take them out in the order that the bottom all came out first) that I noticed a difference. I then took out the rest of the bottom ones to see if they matched the two that were already out that weren't threaded to the top. They did. So I went under the assumption that those were all bottom screws and when I put it back together everything went fine with no resistance.

    So there are three types of screws: Four for the bottom, three long ones as indicated and three others that might be slightly smaller than the bottom ones.

    Although its more than a year since your contribution, I thought you might be amused to know that it is not just that the screws go in more easily when at an angle, Apple actually drilled and tapped the holes at a 15% angle. I too had tried to drive them in straight. An Apple "genius" - I was in for something else - clarified the design for me. It was done so that the screws lay flush on the angled part of the lower case. Nice design, but since Apple encourages DIY memory and drive changes, they could have mentioned this little ... trap.

    Hey everyone, here's the very best way to PERFECTLY organize your screws AND keep track of the order of the procedure: Get a piece of plain corrugated cardboard and a pen (I like using a Sharpie). For EACH step of the disassembly, draw a simple diagram of the layout of the computer on the piece of cardboard, with dots or Xs where the screws are located. Right after you remove each screw from the computer, poke a hole in the cardboard in its corresponding diagram position with your screwdriver and place the screw in that hole. If there are other non-screw related parts to be removed, you can add notes below each step diagram to remind you of where they go or how they should be placed. This cardboard method is great not only because your screws will not go flying or get mixed up by accident if bumped, but each screw goes EXACTLY back where it came from and you can keep the cardboard as a template for future use if necessary!

    These instructions worked great for me. I ordered a replacement battery from Key Power (on Amazon) for my 15" Macbook Pro (mid-2010). Cost was $74 shipped.

    Battery came with 3 different screwdrivers to help with installation. I just needed the one size though, since my 2010 seemed to use all the same size screws.


    Marcos - Ответить

    During re-assembling (put the screws back in), it is important to note that the 3mm threaded holes are not completely vertical, but bent a little bit such that the hole direction is rectangular to the tapered surface. The force of the screwdriver must point towards the direction of the hole. Otherwise the screw gets jammed

    There is a FOOLPROOF WAY TO ORGANIZE ALL SCREWS and other parts removed.

    Print the repair guide.

    Yes, the actual photo of the bottom of the laptop with the circles around the screws.

    When you remove the screw, tape it to the photograph.

    You will tape the screw to the exact location that you just removed it from.

    Same thing with any part you remove.

    Thanks Splash!!! I used your suggested method, and it was perfect: kept all my screws, and i was able to, very easily, put them back in their correct place. I greatly appreciated your feedback. Thank you for sharing!!

    Thank you!!! This worked fabulously - even the I.T. people at my workplace were excited as they never thought to do that before. Replacing the battery took about 10 minutes!

    Worked like a charm! Took less than 20 minutes.

    It's Oct. 2015, and the fan cost me about $10. it was the same brand/model...

    SUNON MG62090V1-Q020-S99 .


    1- no T6 screwdriver- was careful using needle nose players to loosen 2 screws protruding up, then use a small phillips to push real hard into the T6 slots, SLOWLY turn , also used a small flat head screwdriver (for eye glass repair) was able to grab thread on T6's, made a small mark with screw driver across the top so I could see when it started to turn.

    2- no spudger -made one; cut a little strip 1/2" x 1 1/2" of plastic. couldn't get it to slide under plug, there's an edge where plug fits. so lifted old fan out, pulled upward on the plug it popped right out with very little effort. I used my home made spudger to push the new plug into place.

    3- download free "Macs Fan Control" This is how I was alerted to the fan not working in the first place. Program shows temperature of all key components in the computer.

    cheers- Durango CO!

    I will be buying a battery from you and using your instructions. I just installed a new CD/DVD using your instructions and 1) I feel like I owe you something and 2) Although more expensive, I have the confidence your battery will work. My current battery is the original with 1399 cycles in 7.2 yrs. A tech buddy had bought me a replacement and I installed it. I had just installed a new OS and the kernel_task went going nuts, using 90% of the CPU. Hours on the phone with Apple did not resolve the issue. On a whim, I put the old battery back in and Voila! But I cannot risk my battery swelling and going south on me. I am also going to buy your installation tools. Yeah, I already have them. But you can never have enough tools…or beer. And you don’t sell beer.

    The instructions say that I am removing PH00 screws. I found that my MBP, mid ‘12, Retina has pentalobe screws instead!

    jsandersonq - Ответить

    This laptop definitely originally shipped with Phillips screws—but, Apple has been known to replace Phillips screws with pentalobes when one of their devices is brought in for service. Sorry for the rude surprise! Fortunately the correct driver is easy to find nowadays. [Blatant self-promotion alert!] If you support free repair manuals, consider picking one up from iFixit. Good luck!

    Jeff Suovanen -

    Me, too, and it’s plausible that this machine has been serviced by Apple in the past, replacing the screws as Jeff Suovanen suggests.

    iFixit shipped a pentalobe bit with the kit, but it’s too large for the actual screws, so it looks like I now need to get another bit. But what size?

    Jeff’s link is to a driver with a P5 bit, and that page links to a P2 screwdriver, but since I don’t know what size I actually need (and I don’t have a micrometer to hand) I’m reluctant to buy two on spec.

    Norman Gray -

    (The bit in the kit appears to be a P6, so I’m inclined to order a P5 and see what happens)

    Norman Gray -

    You’re using the wrong repair guide. This guide is for the 2012 NON-Retina MBP. You have a Retina MBP. The stock case screws in the 2012 NON-Retina are all Phillips, just as the guide says.

    Steven Wymor -

    To keep track of screws, I used the suggestions above by taping a photo of the lower case to a piece of corrugated cardboard and inserting/taping the screws in place. Also, as some have noted, the screws go back in at a slight angle; they are angled toward the center of the unit.

    Kristina Graham - Ответить

    If your vision, like mine, is getting too fuzzy to be able to distinguish between a tiny Phillips screwdriver and a tiny Tri screwdriver, there’s an easy way. With a Phillips (or a Pozidrive) you can get two opposite wings to reflect the light from a lamp or window straight towards your eye at the same time. With a Tri (or Penta) you can only get one wing to reflect at a time, however much you twiddle it.

    Alan Waller - Ответить

    There’s a very easy way to avoid cross-threading a screw thread, any size.

    Put the screw into its hole and start by turning it gently, slowly BACKWARDS. When you hear a little “Click!” sound, the male thread has just passed the opening in the female thread and is in exactly the right position to enter into it correctly when you start to turn in the correct forward direction.

    Remember, all drivers except hex (Allen key) and TorX need pressure to avoid slipping out and damaging the head. So even when you want to turn it in with LOW moment/torque, keep the CONTACT PRESSURE high.

    Alan Waller - Ответить

    The keep the pressure on is on point. In my case once I loosened my first screw I thought I could relief my initial pressure. It was a mistake. I was doing the whole thing very slowly as a precaution. That helped me notice that the Phillips screw driver was sliding up out of the screw head. Not being sure why, I put pressure back on the screw driver until almost all the screw was out of the hole. Once out, I examined closely to find out that the threads have some sort of coating. It looks to me like some kind of locktite. Then I understood the importance of keeping the pressure on all the way through. It made me uneasy having to keep so much pressure on such tiny screws, but I found it was the only way to prevent damage to the “slots” on the heads. Anyway, all of them suffered some degree of damage, but I was able to successfully remove them and reinstall all of them back in their original holes.

    After reading this page on iFixit several times, I just could not face all the work of replacing the Logic Boards on two MacBookPro 2011s even if I was prepared to pay approx 400 USD (which I wasn’t). Then I read the reviews of a couple of folks who’d stripped down their machines and put their logic boards in the oven and, it worked! I wondered, if I just used my new Steinel Hot Air Tool (heat gun in my language) recently delivered from iFixit, on the logic board in-situ, without removing it? So I removed the battery, hard drive, and RAM and unplugged all the leads I could see WITHOUT removing anything else physically. Then using the 500 degrees set on the gun (setting 2) I ‘played’ the gun over the logic board for about 60 seconds on machine one with the restart problem (plus latterly, not completing start-up). Long story short… it worked! I spent a long time getting the s/w to load, but the commentary is too short to let me relate that part… ping me if I can help you do the same! blackaye@gmail.com

    • For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary but is recommended as it prevents any accidental shorting of electronics on the motherboard. If you do not disconnect the battery connector, please be careful as parts of the motherboard might be electrified.

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket.

    nails work pretty well as well...

    Sibe Jan Kramer - Ответить

    At first sight I was confused when I read the description at this step, 'cause it seemed that disconnecting the battery connector was optional, in order to eliminate static discharge. While it's a helpful advice in other circumstances (as mentioned as an example changing hard drives), when changing the battery it is not an option - you have to disconnect the battery connector.

    It would have been better to mention the optional disconnecting recommendation in a side-note.

    Other than that, an excellent guide!

    Damienn - Ответить

    the fact that this step is optional can not be stressed enough. i tried disconnecting the battery and in the process it short circuited which now leaves me with an even more expensive problem than i had before when i just wanted to change hard drives (at least the new hard drive works fine..)

    the hard drive changing worked though.

    nina - Ответить

    Any tool used to pry on the battery connector must be non metallic, to prevent unintentional short circuit between the connector pins. In my case, my index finger nails were strong enough.

    Martin Mejia -

    Excellent guide, it was as easy as a breeze to replace my battery. I can't believe I nearly followed Apple in their saying that this part was not user replaceable. Great job for this description, and many thanks. iFixIt is THE reference for Mac owners.

    So - I have a weird comment about this. I wanted to make sure that I was getting the right model - so I opened up my laptop and then thought "well, why not just remove the battery while i'm in here, it's shot anyway". Though, I forgot about the stupid screws (Apple really did us over on that one!). Though I disconnected the battery connector and didn't bother to re-connect it when I was finished and just put the cover back on.

    Here's the weird part - when I went to turn my laptop back on...MY BATTERY WAS RECOGNIZED...AND WORKING! I was under the impression that the connector "connects" the battery's charge to the laptop, but this just doesn't make sense! Plus, now my very dead battery is in "normal" condition according to the system report. I haven't worked for apple, but have about 5 years of IT experience and am baffled by this! I'm starting to think i've experience a miracle! Has this happened to anyone else?

    Shelly - Ответить

    Possibly disconnecting the battery caused the System Management Controller to reset. That might have been your problem rather than the battery itself. See http://osxdaily.com/2010/03/24/when-and-...

    Mazo - Ответить

    I tried spudging the corner closer to the wires which was probably a bad idea. The corner broke off! I can't believe it was that brittle. So be careful. If it did it again, I'd aim for the corners AWAY from the wires or the sides themselves, though I seem to recall there not being much of a lip.

    Dave Kitabjian - Ответить

    I used the spudger to gently ease the battery connector out. I then placed a q-tip between the connector and it’s socket to avoid making an accidental connection. A toothpick or some other soft stick might also work.

    Kristina Graham - Ответить

    My battery connector had a shiny metal cover over it like a male USB plug. I had to take the 3 peace symbol screws oit and remove the battery before I could access thr plug properly. My battery plug also came off parallel to the board by walking the black plastic part off the metal part towards the battery. It required quite a bit of force to walk it off the connector. I broke a spudger trying. Something nonconductive but strong like a wittled down bamboo chopstick could work well.

    Translate to Spanish:

    Para ciertas reparaciones (por ejemplo, el disco duro), no es necesario desconectar el conector de la batería, pero evita cualquier cortocircuito accidental de la electrónica en la placa base. Si no desconecta el conector de la batería, tenga cuidado ya que partes de la placa base pueden estar electrificadas.

    Use el borde de un spudger para levantar el conector de la batería hacia arriba desde su zócalo en la placa lógica.

    Es útil hacer palanca hacia arriba en ambos lados cortos del conector para "sacarlo" de su zócalo.

    Pakito Villaseñor - Ответить

    The BATTERY MUST BE DISCONNECTED - it is NOT OPTIONAL if you are going to remove the logic board.

    These instructions are for Removing The Logic Board, so if that is what you are going to do the battery MUST be disconnected.

    The informational item beginning with the words “For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary … “ is NOT applicable to a set of instructions on removing a logic board and it should be deleted from this otherwise excellent set of instructions.

    Michael Walsh - Ответить

    In my opinion the RAM should be removed first - i.e., before the battery is removed.

    The RAM DIMMS are just in the way if they are left in their sockets on the logic board until step 33.

    I cannot see any useful reason to not remove them very early in the sequence.

    I disconnected the battery because it is an opportunity to reset the SMC (which is how the SMC has to be reset in some older Macs.)

    • Pull the camera cable connector straight out of its socket on the logic board.

    • Pull the cable parallel to the face of the logic board toward the optical drive opening.

    This step did not provide enough direction and is the reason my cable is either broke/not working now. I tried pulling it out of the logic board, as indicated, but it did not budge. I was extremely careful not to damage it, so I gave up on trying to remove it once I saw that it wasn't moving. Lo and behold, once I fired the Macbook up again, the camera is no longer connected. This step should have additional details/explanation as to why the cable may not come out/what to do if it doesn't (I was able to proceed to the next steps by working around the cable, so it didn't even have to be removed as the guide might have you think).

    Does anyone know how to properly fix it/where to buy a replacement camera/iSight cable? I would like to fix this if possible.

    I would like to add – several months later, my Macbook Pro failed to turn on and the motherboard had to be replaced. I'm giving partial blame to this guide for failing to adequately describe how to safely proceed on this step (I suspect a bad wifi card was part of the problem).

    • Use the tip of a spudger to pry the four antenna connectors up from their sockets on the AirPort/Bluetooth board.

    I found the problem with my wifi: sadly the connector solder joint j4 of the wifi board was not stable enough. now the socket is inside of the connector and not joined with the board. How do I remove the socket from inside of the connector? Is this even possible?

    Bodo Tasche - Ответить

    Replying to Bodo Tasche:

    The antenna connection sockets are only held onto the wifi board with solder, on two small pads, so it is easy to break one of them off, I have done it on one occasion. I was able to pull the remains of the socket out of the antenna wire plug with tweezers, but had to replace the damaged wifi board with another one.

    Here’s another thing to consider if your Unibody MacBook Pro has wifi problems: Your wifi ANTENNA. The antenna is mounted in the center of the display hinge. The antenna wires — the same ones that plug onto the wifi board — can break from repeated flexing at the point they pass through the hinge into the display. This was the cause of my wifi issues. Swapping the wifi board made no difference.

    If your wifi connection stats show consistently very low signal strength and signal-to-noise, even with a nearby access point, consider the possibility that the antenna may need replacement. (It’s a difficult repair, and iFixit doesn’t seem to currently have a guide for it.)

    I would leave these attached and just dangling if you don’t need to replace the Airport/bluetooth board. They’re a pain to reattach and breakage seems somewhat common.

    maccentric - Ответить

    If you DO end up detaching these, I found it easiest to pry up gently from the wire side to remove, but also the reattach them the same way, with the wire side high. That means you want to tuck the cables AFTER reattaching them, except for the longest one of the 5, which needs to be tucked first. Be careful all quite delicate.

    I stripped out the 3.9mm Phillips screw yesterday; tried the rubber band trick without success. Ended up taking a 1/16” drill bit and drilling just through the top of the head of the screw (head popped off) allowing the bracket to come out. I left the body of the screw in the post; upgraded my card to 802.11ac, and the upgrade doesn’t utilize the bracket.

    If I really wanted to, I can grab the exposed portion of the screw body with some vice grips and rotate it out…

    So far I have "successfully" )-: stripped the head of the screw on the right of the diagram (above, step 9), as many others appear to have done, but not dared to proceed any further until I figured out how to remove that screw without breaking the frame of the wifi/bluetooth assembly or anything else?

    How did you solve this problem?

    • Peel and remove the piece of EMI tape wrapped around the AirPort/Bluetooth assembly.

    Where can I get a new piece of EMI tape wrapped around the AirPort/Bluetooth assembly?

    Use a blade to pick up this tape as it easily tears. Take your time with it and stick it to a clean plastic surface so it doesn't curl. It'll then go back on OK. I suggest you replace with the longest edge first and carefully wrap the tape back on when replacing.

    Rich Moog - Ответить

    I’d suggest starting on the larger side with the tape and working around to the smaller side as it is easier to deal with the curling that happens on which every edge is lifted first if it is on the larger side versus the smaller side.

    Also seems like starting with the spine of the tape when replacing makes alignment easy and pretty foolproof.

    But really starting with a new piece of tape would be best. Doesn’t stick back down nearly as well and there is a tendency for it to fray when being removed. Wish they alluded to that at the beginning of the guide.

    • Use the flat end of a spudger to pry the AirPort/Bluetooth cable away from its socket on the AirPort/Bluetooth board.

    • Remove the AirPort/Bluetooth cable from the AirPort/Bluetooth assembly.

    • Remove the three Phillips screws securing the AirPort/Bluetooth board to the AirPort/Bluetooth board housing.

    • Use the flat end of a spudger to dislodge the AirPort/Bluetooth board from its recess in the AirPort/Bluetooth board housing.

    Does anyone know what size screws these are? I stripped one of them pretty bad. My best guess is m2 3 mm but I could be way off. Can’t find the exact screw type anywhere.

    • Before securing the AirPort/Bluetooth bracket to the upper case, be sure the small tab on its left edge is inserted into the small void cut into the black plastic optical drive opening.

    No need to buy the bracket for this repair. The only thing you need is the chip, unless somehow your bracket is broken. Which would be very unlikely.

Pessoal; Será que temos com trocar essa peça Bluetooth 2.1 por um 4.0?


Folks; Do we have to change this piece Bluetooth 2.1 for a 4.0?


Fernando Medeiros - Ответить

My computer was having trouble with the internet and after much research I came to the conclusion it was my airport/bluetooth board. A bunch of stores I went to said it would cost me around $200-$300 to replace ($100 for board and $100-$200 for installation). Then I found this cite and all of its manuals. I was able to order the part online from this site for only ~$50 and following the steps in the instructions was super easy. Would definitely give 10/10 for this website and manual.

I'd also like to point out I ordered the ifixit tool kit as well (just cause it looked awesome and I have no will power), but only the 2 tools mentioned in the instructions were needed. So no need to go overboard such as myself

Hi, would there be chance that the ribbon that is broken? My mid 2012 MBP faced a few times of this wifi/bluetooth issue but the technician never tell me what is the real problem. Or I can just buy the adapter and replace it by myself?

JinHow - Ответить

Good chance it is the ribbon. I replaced the board with the one I ordered from this site. Worked great for about 2 months then had the same issue. Figured out it couldn't be the board that was causing the problem. So I played with it and I think it's my ribbon connections. All I do is every few months when I start to get the problem I open it up and reconnect the connections on the ribbon and it's good for another 2 months. I assume a permanent solution would be to buy a new ribbon but I haven't done that yet

Darren Picard - Ответить

I second this. My old computer started having bluetooth issues and I needed more power, so I bought a new one and gave the old to my wife. WiFi went out shortly thereafter. PRAM resets worked for a few minutes, but never very long. Replaced the ribbon (very easy, a bit cheaper), and bluetooth works great now, and wifi too. I would try the ribbon first (cheaper and much easier to do).

I just want to say thank you SO MUCH for this comment. I’ve been having a “no hardware found” error with my wifi and when I called Apple they told me the chip is very difficult to get out and it would probably be better just to get a new computer (of course). That was about a week ago: now I’m working on my old iPod and it occurred to me to check out MacBook parts. One thing led to another and BAM! I followed your advice to tighten up the connections and I am back up and running! Now I know I can look at the ribbon if this happens again, before resorting to a new computer or even a new chip. So again, thank you! :)

Just a little update for those that care, but I ordered the ribbon from the site and installed it on my macbook. I have had no issues with my internet since doing this so I assume i have solved my problem for now. Hope this helps

Darren Picard - Ответить

Thanks for the followup, I will then replace my ribbon too.

Degeorges - Ответить

@darrenpicard25 What were your specific issues? And can you provide a link to buying the ribbon? My Bluetooth works if I turn off WiFi. Otherwise they compete, my mouse gets choppy and often loses its Bluetooth connection.

Macgeekppc - Ответить


Basically the problem I had was my WiFi wouldn’t work. If I connected my laptop directly using a cord the internet worked, so I knew it was something with my wireless card. It would say that it was on but would not show any of the networks around me. and If i turned the WiFi off it wouldn’t let me turn it back on again (id just click the button and it wouldn’t do anything). So then Id restart my computer and sometimes my WiFi would work, sometimes id have the same problem, and other times it would say “No hardware found” (then id have to restart it again until it worked). This would solve the problem for a few days or as little as 20 min, it varied. I googled a bunch and tried a bunch of things on my computer like removing the Wifi and adding it back on but these only worked temporary (same as just restarting it). So then the next steps I did are in above comments, but yeah it was definitely the ribbon cause it has been working fine since

Hello iFixit

I am having trouble with my wifi etc. I followed your helpful steps and when I got to ‘step 6’ I realised why my airport wasn’t working anymore.

The ribbon is loose from its socket and the socket element itself is stuck to the logic board and wont budge. Do you have any suggestions on how to remove this or even why it would be stuck to the logic board…?

All the best


dougal - Ответить

Do I need to reinstall any software to reboot the card? After replacing, allegedly, faulty card my wifi is still not working, on the top of that the bluetooth is disabled too.

What to do???

przemek - Ответить

When you reboot your computer following the installation, make sure to reset your system clock, as most websites will not allow you access without a correct clock.

@darrenpicard25 how did you fix your rubber problem? It sounds like I have exactly the same problem as you have.

I assume you mean ribbon. But I just ordered the ribbon from this site and followed the instructions to replace it. It was pretty straight forward

Hello, thank you for this tuto! do you know if we can upgrade the airport card from this macbook pro mid 2012 with another to unlock my mac with an apple watch?

Lopez - Ответить

I replaced my 2012 15” MacBook Pro Unibody card with a 802.11ac + BT 4.2 card from Subtle Design (https://subtle.design/collections/techno...). Working great so far; found on MacRumors (https://forums.macrumors.com/threads/802...)

This allows unlocking with Apple Watch—I’ve done it successfully once; but still need to reset my SMC and restart my computer…

I’ve changed the board as mentioned above but I still receive the No hardware installed error… even after resetting SMC and NVRAM…

How can I solve this issue asap?

Thank you.

I found that QuickerTec now has a replacement 802.11ac Wireless upgrade card (with BT 4.0) to fit the 2012 15” MacBook Pro. The card is called the uCard4 and costs $149 (plus tax and shipping, I assume). Anyone have any experience with this? I imagine these instructions would work as well. Any tips? Comments?

I had an order pending for almost a year before I cancelled it. Found Subtle Design through MacRumors — https://forums.macrumors.com/threads/802...

Installed yesterday; working well.
