Replacing the hard drive requires separating the display and removing the left speaker.

This guide also includes steps to upgrade your iMac's hard drive with a SSD. It describes how to install the SSD's temperature sensor so that the Mac's fans will operate at the correct speed.

Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

Video Overview

  1. Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" (9.5 mm) into the display. You risk severing antenna cables and causing serious damage. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far.

    Would a heat gun make this step easier? Or damage the iMac?

    A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

    Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

    When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

    Walter Hayden - Ответить

    Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

    I can confirm with Walter - trying to remove freshly applied adhesive is WAAAAY harder! My pizza cutter didn’t work correctly (the circle became a rectangle!) and I ended up with a small crack on the left of my screen. Dang it!

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

    Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

    I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

    First impressions so far: yes it can be a bit nerve wrecking if it is your first time doing this sort of thing and even with lots of experience with a 2011 model it’s still a bit unsettling haha (nervous laughter).

    What I recommend: use a guitar pick to start cutting the glue. You’ll need a bit of pressure so do just the tip.

    Once you’ve done the whole perimeter (minus bottom) do it again but now it should be easier to go deeper so go very slow and careful. Then get the old suction cups used to open older models and start lifting the display very carefully to see where it’s still glued and cut those as well.

    Then you should be done and now the real fun begins! :D

    It’s ridiculous. Apple should pay for doing this. Like glue parts together to block a repair / make difficult. I smashed my iMac. FU Apple. Seriously, every product I owned had hardware issues. For example, bad solder joints. Never again Apple. I’m happy with Windows and in 2018 / 2019 there are many other manufacturers with high quality stuff. Apple is dying, if they do not change …

  2. Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center. Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle. Run the tool up along the left side of the display.

    I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

    My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

    Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    • If there is a wire or cable underneath adhesive tape, always pull the tape off first.

    Be extremely careful removing the LCD Temp Sensor from the rear of the screen. If you pull the wire, you run the risk of severing the metal wire from the connector but not notice it because the surrounding plastic insulation may still be intact. Use a razor blade so “shave off” the sensor under the adhesive. I just had the screen replaced by a local shop and, upon boot, the fan was running full-speed and the Mac’s speed was miserable; Excel took 30 bounces in the Dock to launch rather than the expected 4-5. Novabench showed the Mac running at 4% of its expected speed (overall). The tech examined the sensor carefully, found the broken connection, soldered it back into place, and all was fine. Note that the (partially disconnected) sensor actually showed up when I ran Macs Fan Control in an attempt to work-around this. No problem controlling the fan speed then but the iMac’s running speed was awful until the disconnected sensor wire was fixed.

    Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

    If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

    Hi Walter, i’m looking to replace the broken fusion drive with a SSD, do i have to get the OWC’s Thermal Sensor HDD Upgrade Cable?

    Gregorio Alvarado Sahli -

    Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

    Hi Lynne,

    It does not have to be connected to metal. However, the sensor should be stuck on the drive and not on the enclosure so that it can sense the drive’s temperature.

    My iMac (27-inch, Late 2013) (Model Identifier: iMac14,2) (EMC: 2639), had a Seagate Barracuda 1.0TB HDD installed. There was no temperature sensor on the HDD. I have the Fan Controller that is pictured in this manual on Steps 39, 40 and 41. The photos do not show a small two-conductor cable connected from the Fan Controller circuit board to the logic board. There is usually a cable that connects the small circuit board, where the drive’s temperature is measured, to a connector on the logic board, but not in this iMac. For now, I have installed the Samsung 860 EVO 500GB SSD without a fan controller and it has been running for over two hours without a hint of the fan ramping up. Should I still install the Fan Controller and not worry about connecting the controller sensor to the logic board? Thank you for creating an excellent manual!

    You can use Mac Fan Control as a software solution. You won’t break your computer as it will slow down and throttle itself to protect it. More than anything, your SSD will run warmer than usual, which could shorten its lifespan.

My experience in upgrading this unit to a Seagate 4TB hybrid ST4000DX001 went fine except for the fans running at a constant higher RPM. Using Macs Fan Control is solving my issue for now. As a tip, you do not need to remove the left speaker, you can loosen the two screws and angle it leaning to the left.

What setting do you change in Macs Fan Control? Im looking at getting a SSD fitted to my Late 2013 iMac by a certified repair centre who have said they will do it for me if I provide the SSD but they did mention that the fans would most likely speed up as there won't be a temp sensor in the SSD. Thanks.

Lewis: simply running the Macs Fan Control app will do it. Otherwise the fans run at full speed because they have no temperature measurement.

Tim - Ответить

To solve the fan issue I believe you need to add a temperature sensor like this: http://eshop.macsales.com/item/OWC/DIYIM... OWC told me if you don't, your fans will go crazy because the new drive probably does not this sensor like the original mac. Just heard it today and then read this. Hope this helps!

I have put 1st a 500gb and after a 1tb ssd both Samsung evo 850. I didn't needed to use the OWC in line thermal sensor, I even have bought it but first upgrade it hadn't arrived yet and I wanted to know if I would really need it since I have read somewhere that the latest versions do not need it anymore. my imac is a late 2015 and I am not sure if really is the fact of it be a newer version or if the Samsung evo 850 have some thermal sensor inside. by pass, the ifixit adhesive and the included apener are both great. it was very easy to replace the hard drive, however replace the processor as a little bit hard but I had success in doing it

I did the installation of a new hard drive following the ifixit guide, afterwards I had the fan issue, I did not have the fans spinning at full speed like some people have been describing but the CPU and other components would just get hot very fast, this seemed very strange, installing Mac fan control didn't help much, as the CPU and stuff would heat up, and if I did not want to damage my computer I had to crank up the fans. I was desperate for a solution, so I purchased the kit from OWC (after reading "weddings" comment) being a bit sceptical, because I wasn't sure if installing a sensor would stop the CPU from heating up. But after the Installation everything is back to normal. The CPU stays at around 40 degrees, and the fan stays quite. I don't understand how this works, but I definitely recommend installing this sensor if you have similar issues after upgrading your hard drive, even if it means opening your iMac again ;). For the record: I have an iMac 27-inch Late 2012.

Thank you for this guide: very clear and detailed. The dedicated adhesive-cutting tool was well worth the money, as it sped up the cutting and reduced my stress level! I did need to repeat steps 9-16 a few times before the screen felt loose enough to lift away from the body. TAKE YOUR TIME - the screen WILL lift off without much force when it’s ready.

While the case is open, allow a few minutes more to remove the left speaker and carefully remove any dust and fluff that has been sucked into the case by the cooling fan!

I opted for a 2 TB FireCuda drive. Booting up and loading of apps is noticeably faster, for only a few pounds more than a 2 TB traditional HD: a cost-effective solution for an older Mac.

Hi all. I have a 27” iMac (2013) but it was configured with the BTO 500gb Flash/SSD blade on purchase, so didn’t come with a HDD fitted. I want to add one (either a high volume spinny disk or another SSD, I can’t decide yet!), but I’m wondering what parts I’d need. I couldn’t imagine that Apple would include the driving mounting parts or SATA and power cables for a machine that was ordered without an HDD. Has anyone cracked one of these SSD only iMacs open to see what’s what?

markbart - Ответить

Did this for a customer at my shop. Used all iFixit tools and parts. He called back 3 weeks later because the screen fell out. What causes this? Can the iFixit adhesive strips be trusted? We’re out $600 because we have to replace this screen now, and we can’t even be sure that it will not happen again. What can we do?

Alec - Ответить

@fletchertime Sorry to hear that :( In my experience, the replacement adhesive is extremely sticky, so I’m not sure how this could have happened. The only possibilities I can think of are (1) the old adhesive was not cleaned off well enough, resulting in a poor bond for the new adhesive, (2) the customer broke it on their own somehow, and is trying to pin it on you, or (3) the adhesive was defective in some way—certainly possible, but we haven’t heard of any other instances of this. If you ordered from iFixit, at least reach out to customer support and see what they can do to help. Better luck on the next one I hope :(

Jeff Suovanen -

What you used to clean the adhesive could have left a film which interfered with the adhesion.

Rubbing, ethanol isopropyl alcohol can have junk in them that could have messed you up. You really want to use reagent grade (85% or better). To test your solvent is to get a small glass bowl to place some of the solvent and carefully warm it no flames! to speed up the evaporation do you have any staining at the bottom.
