    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs are fast and easy with an iMac service wedge, but can be completed without one.

    • If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • 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. Only handle the board by the edges.

    The wedge is an extremely tight fit for this model. I was worried that the amount of force needed to use it as shown might damage the stand, so I used it with the long side down instead. It worked fine that way and didn’t need anywhere near as much force to insert.

    Here are a couple tips from me:

    1) Expose the adhesive to extreme temperatures. I did this by transporting my iMac in my car, screen-down on a piece of cardboard on a cold February morning (in Chicago). When I went to pick up the iMac, the screen practically fell off the chassis. I would have been distraught by this if I hadn’t already planned this replacement. So it was a happy accident.

    2) Remember to expell the residual power from the power supply by pushing the power button while the iMac is unplugged. This does NOT guarantee it’s safe to touch, but when I accidentally brushed the solder and exposed capacitors, I didn’t get shocked.

    Instead of using the wedge, I placed the iMac faced up with the top side (web cam) facing me while I ran the pizza roller around. It worked out great!

    There is no replacement glass for this model, it is part of the LCD and impossible to remove or replace- the entire LCD has to be replaced unfortunately if the glass is cracked or damaged. You will have to Google search for a replacement. Also be careful with some of the lock tight tork screws as I broke one of my screw mounts taking one out.

    I used this service wedge but also found it a very tight fit. The same stabilization can be achieved by using a big rolled up towel.

    While this is a good instruction guide, I recommend to also look at OWC’s instruction video about drive installation, before starting the exercise. Those install videos are very detailed and useful.

    Ernst - Responder

    Main advice: TAKE YOUR TIME with the pizza roller.

    Make several passes, until you really feel like there's no more sticker in the way. Stay away from the camera though (approx. 1inch / 2.5cm on both sides). This will reduce the work left with the plastic card. Adhesive is really on the edge of the screen so there is absolutely no need to go any further than the recommended 1cm / 3/8inch depth.

    Where are the sensitive parts?

    Facing your iMac, imagine you're looking at a watch. There are antennas on 1, 2 and 4 o'clock. Do not insert any metal piece there (nor anywhere else, btw). Other than that AND the screen cables underneath the camera, not much danger.

    • 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 enclosure.

    • 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" into the display. Otherwise, you risk severing antenna cables and causing serious damage.

    Don’t get too worried about starting exactly where the picture says. The glue is stronger in some parts so just start wherever is easier and then work slowly and patiently around in the direction shown.

    As this guide doesn’t cover replacing the adhesive strips, I found referring to the following was useful (noting that it’s not for the same model of iMac, so the modification they mention wasn’t necessary): iMac Intel 21.5" EMC 2544 Adhesive Strips Replacement

    It is very easy to crack the glass in front of the LCD during this step. I used the guitar pick, maybe it was too thick… crack is just on the frame but anyway it is disappointing :(

    Nikolay - Responder

    This part of the exercise should be done with extreme patience. I took my sweet time with the opening tool, rolling it through the entire panel and enclosure gap over and over again, until I was very sure no parts were sticking together anymore. And when I thought I was I done, I decided to do it over again.

    Ernst - Responder

    You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

    • 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.

    If re-opening a screen that was opened and re-attached using iFixit’s adhesive strips, I would strongly recommend heating it first with an iOpener, heat gun or hair dryer. 20 minutes after attaching with the iFixit adhesive I tried to open it again with the pizza slicer to fix something and cracked the screen on the left-hand side.

    • Continue along the top of the display.

    • You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.

    In this step can I cut along the display without make any damage to the front camera?

    Hi! Actually - there is no need to cut the tape around the camera area - there is no tape to cut at all! And so, the way go is easy - just pass 10 mm to the left and to the right from camera and start cutting!

    P.S. Just did the whole procedure to replace a RAM and to add SSD on PSIe an hour ago! Seems to be different reading the instructions... you know - 2/10 and so on. But it's really not that hard, trust me. I'll give it 5/10.

    P.P.S. By the way there is one trick to pass the difficult steps. Any action which requires pulling smth (motherboard, speaker, power supply unit) from the narrow crack (or should i say - slit?) at the bottom of your Imac is really not so easy.

    And the trick is to first remove a thin metal stripe with some kind of insulation on it which held by 5 small (very small!!) screws at the bottom of your Imac. After you done it - it's easy to pull everything! Pay attention to the fact that one of this 5 screws at the center are more shortly than others.

    If you're changing cracked EMC 2638 display to new assembly, there's two more steps:

    Step 24: Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.

    Carefully pull the display data cable from its socket on the display assembly.

    Step 25: Use the tip of a spudger to unplug bracket of the thermal sensor small cable near display data cable.

    Carefully remove scotch tape covering thermal sensor. Using iSesamo or flat tip of the spudger carefully peel the thermal sensor away.

    The key thing is to never put any force on the opening tool when working through the tape. Just roll it back and forth with ease.

    Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

    • While the opening tool cut most of the adhesive, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.

    • Set the iMac face-up on a table.

    • Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.

    • Be careful not to insert the plastic card more than 3/8", or you may damage internal components.

    this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………

    • Gently twist the plastic card sideways to create a gap between the display and frame.

    • Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".

    This part must be done very carefully or you can damage the flat cable from display, despite it was under a iron cover.

    • Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.

    • Be sure to stop before the iSight camera, or you may damage it.

    You don't need to do it like this, simply open the iMac bendidng the LCD completely and use the pizza cutter to remove the adhesive.

    • With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.

    • If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the remaining adhesive.

    • Begin to lift the top of the display up from the frame.

    • Only lift the display a few inches—the display data and power cables are still connected to the logic board.

    • Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

    • Hold the display with one hand while using your other hand to unplug the display power cable.

    It was difficult to remove this connection. I ended up having to gently pull-up vertically a little on the wire side to unsnap it about 1mm and then horizontally wiggle it out.

    I had a difficult time removing this connection. I had to lift the wire-side about 1mm before it unsnapped and then carefully wiggle it out horizontally.

    Can this cable be replaced? I am worried mine is damaged. I have no display after the screen fell and stressed the display flex cables following an SSD upgrade.

    Jeremy Brainard - Responder

    This step should be done with extreme caution and care, as this step 19 is not described in great detail (sorry, author).

    The first (most outward) cable will slide out by gently pulling it by its tabs. The second (inner) cable is more tricky, as the locking lever must be moved backward first, before gently pulling backward on the cable connector. The angled tweezers are useful here, to help lift that locking lever, because fingers are too big for this.

    Ernst - Responder

    be VERY careful and SLOW...take your time. These displays crack VERY easily when removing and they'll spider web on you. I've done probably 20 or so of these and cracked 3 being super careful.....ugh.

    Faslane - Responder

    I found the best way to unplug this display power cable was to use my right hand, and the fingernails of my index finger and thumb to grab the ends of the tabs on either side of the connector, squeeze, and pull the connector out gently.

    Phil McInnis - Responder

    i think the cable nearest the case edge is held in by friction and can be gently pulled, maybe with fingernails or a spudger. The next cable is held by a wire lever clip as described above it unlocks so the cable can be removed. These cables are also fiddly to re-insert, I didn't get one of them home and had no display after power-up, so at the end, don't re-seal the screen until tested.

    • Continuing to support the display with one hand, flip up the metal retaining bracket on the display data cable.

    • Carefully pull the display data cable from its socket on the logic board.

    • Be sure to pull the display data cable connector straight out of its socket, keeping it parallel to the motherboard, to avoid damaging it.

    Cannot seem to find a replacement cable for this, as I suspect mine is damaged. Can’t even find a part number. Anyone know what it might be?

    I also need that cable.

    cameronjpu - Responder

    It's a little difficult to tell... but looking at the connection to the logic board on the video data cable, are the pins faced up or down?

    On the display, same question since it appears you have to "twist" the cable during the reconnection step.

    Jim Stanford - Responder

    For this particular cable, take a good look before pulling on anything. Plug is locked on its socket with a bracket. You can lift this bracket by holding the small, flat black plastic handle that is attached to it. If you're struggling to grab it, use the end of the pizza roller handle to lift it, or the tweezers. Cable then comes off by pulling parallel to the main board.

    Froggy Manny - Responder

    How can I tell if either of this cable is bad? My iMac display won't turn on after reconnecting it. I'm using an external display and everything is working except for the iMac display. If I go to settings - display the built-in display is recognize. But again nothing shows up in the screen - not even the apple logo when turning it on.

    • Lift the display up to a near-vertical position.

    • At this point there is still a strip of adhesive along the bottom of the display that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.

    • Repeat this step with the other adhesive strip and remove it.

    • If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

    Vorsicht: Wenn man den Bildschirm einfach versucht vom Kleber wegzureissen, besteht die sehr grosse Gefahr, dass danach der Bildschirm tatsächlich defekt ist, was daran zu erkennen ist, dass dieser bei der Inbetriebnahme schwarze Diagonale Striche oder Lücken enthält. Dann muss der ganze Bildschirm ersetzt werden, was dann recht teuer wird!

    Caution: If you simply try to tear the screen away from the adhesive, there is a very high risk that the screen will actually be defective, which can be seen from the fact that it contains black diagonal lines or gaps during commissioning. Then the whole screen has to be replaced, which then becomes quite expensive!

    • Lift the display up from the frame and remove it from the iMac.

    • It may be necessary to slowly lift from one side to peel against the remaining adhesive.

    • Be very careful handling the display—it's big, heavy, and made of glass.

    • After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide to replace the adhesive strips that secure the display to the rear enclosure.

    2 notes for reassembly, carful with screws not to strip the heads as they are really really small, make note to cut a gap in the the adhesive over the whole for the microphone.

    I managed to strip the head of one of the screws when putting it back in. So be carful with them when putting in / taking out. If you strip it on the way out you will need to take a fine drill and rill it out. Going back in, well as long as you never need to strip it down again not a problem.

    The second problem is a real pain, you need to make sure to cut a gap in the adhesive just to the right of Center at the button to allow for the microphone opening. If you don’t, the adhesive tape will stop any real pick up on the Mic, so you just need to cut a small gap in it before putting on the screen. Unfortunately I didn’t find this out (or do my checked before sticking it all back down, so have to pull screen back off and reapply new adhesive with a cut out in it at an other time.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

    • Do not let any of the exposed solder joints come in contact with a metal surface, as that can cause a short.

    • Flip the power supply over to access the DC power cable connection behind the logic board.

    • To disconnect the cable, squeeze the release clip on the back side of the connector, behind the logic board, and pull the connector straight out.

    • You may find it helpful to set the iMac down on its back for the next couple of steps.

    • Use the flat end of a spudger to press the release clip on the side of the AC inlet cable connector inward.

    • While pressing on the release clip with the spudger, grasp the AC inlet cable, and pull the connector straight out of its socket.

    I didn't bother to remover the power supply lead in this stage but simply flippedthe circuit board over onto the lower body of the iMac (NOT placing it directly onto the metal but onto a sheet of plastic)

    • Use a spudger to disconnect the single SATA power and data combo cable by gently prying its large plastic connector away from the hard drive.

    When reconnecting the SATA cable, there is nothing to make the connector hold still, and it is hard to reach, so it took several tries. I ended up taking off the rubber baby buggy bumpers to get more room, and then jamming them back on after getting the SATA connector snugged up.

    If by rubber baby buggy bumper, you mean left speaker, then yes, I agree. Reinstall the hard drive before the left speaker.

    Kudo to @jerrid_foiles! I was going crazy trying to attach the SATA cable until I took the two screws out of the left speaker and slid the top end of it aside by about 3/4 inch. Make the whole process SO MUCH easier!!

    We solved this by removing the hard drive tray screw, then inserting the cable into the SATA hard drive. Then hold the hard drive a bit out of the way to insert the 7.3mm hard drive tray screw.

    Agree with this method, found it an impossible task to reconnect the SATA connector until removed the tray screw, then it was relatively easy to reconnect and then replace the tray screw.

    And DON’T do what I did, which is to remove the left speaker - which can easily lead to breaking the cable between the power on button and the power supply. The cable is routed through a hidden slot at the very bottom of the left speaker

    bsmith1 - Responder

    I did loosen the speaker so I could get a tool behind the SATA cable to push it on to the SSD drive. Otherwise hard to align cable.

    Noah Ralston - Responder

    I found the easiest way to connect the SATA cable was to not screw the plastic hard drive tray down until you plug the drive in. That way you can easily push the connector in and due to the cable you’ve got some wiggle room. You can position the tray then just lift one end of the drive up and secure the screw. Then just push the drive down.

    Chris Caldwell - Responder

    This was the step that I had the most trouble with. I’m used to replacing a hard drive in a MacBook Pro, where the “plug” that you plug the drive into is a rigid thing that you can firmly press the hard drive into.

    With the iMac, the plug is situated on the end of a non-rigid cord, so the plug moves back when you try to snap a drive into it. Also, those two rubber gasket things that you adhere to the side of the drive really make it difficult to maneuver the now-overly-chubby drive towards the plug.

    After must frustration/concern, what I ended up doing was temporarily removing the rubber gasket things, using the “spudger” as kind of a lever behind the “plug on a cord” so that it didn’t move as much, and then pushed the gasket-less SSD into the plug.

    Once I got it connected, I put the rubber gaskets back on the sides of the SSD and kind of coaxed it down into place, using the pointy end of the spudger to get the chubby corner pieces to “sit” correctly in the rigid plastic tray that the SSD kind of rests in.

    From another comment elsewhere on this repair, I *highly* recommend removing the two screws holding the left speaker in place, then sliding it just a tad out of the way to be able to easily attach the SATA cable. You don’t have to move it much to make the whole process so much easier!

Thought this was going to be extremely difficult but once I started with these instructions it actually wasn’t that bad, though it took me a slow and careful 3.5 hours. Was quite nervous handling that power supply though!

Chris Caldwell - Responder

Excellent guide! It took me about 1.5 hours to complete the entire RAM+SSD installation. The iMac has massively improved and feels like a new computer: way way faster than before, with a 1TB Samsung SSD, 32GB of RAM and a brand new installation of macOS Catalina. Be very careful with the I/O ports, especially with the USB-C/Thunderbolt ones: the alignment is critical, as well as the correct position of the logic board in relation to the case. Even a slight misalignment can impede the USB-C plug from fully entering the port, making it hard or impossible to establish a connection.

Mattia - Responder

Great guide… took a mediocre “unupgradable” iMac to 32 GB ram and new SSD HD (the other guide… but crosses with this). Excellent guidance. If you have to fix or upgrade anything else while changing out the RAM, this is the time and performed steps to do it with. Read the others to see the variations you need to do (like steps to clone the HD before changing, etc.) but as deep as you get into this machine, it exposes pretty much everything. Again, great work!

Wonderful guide! I was afraid that I am not going to make it since I don’t have a lot of experience in such things but following the steps carefully, paying attention to every detail, has led me to successfully upgrade my iMac 3086 with 1TB SSD and 32GB RAM. I was really afraid that this RAM upgrade probably won’t work because it’s been said on everymac.com that the maximum is 16GB and I’ve read somewhere about a person whose iMac didn’t even start after such intervention. I decided to purchase Crucial 2x16GB at 2400MHz, despite that the iMac has 2133Mhz bus. I trust this brand and I’ve already upgraded my MacBook Pro 15” mid-2012 with the same brand, again pushing the RAM beyond the official limits and it still works great. The SSD I put here is also from Crucial and I just turned on the iMac and it runs like never before! The whole procedure took me a bit over 2 hours. Thanks for the great work with this guide!!!

Alexandra Zerner - Responder

Hey Alex, I’m also worried about the compatibility of the Crucial RAM, so could you tell me which especific model did you use, please?

bruno.kato -

I did this, while also replacing the hard drive. Four mistakes: didn't check alignment of USB ports before reassembly (now I can't fit a USB cable in one of the ports), I put the adhesive on the bottom part of the screen on backwards (not addressed in this tutorial at all), the alignment of the screen with the chassis is slightly off, and I didn't wipe the camera lens with a microfiber cloth before I adhered the screen to the base (little smudge that drives me crazy; also not addressed here). Overall, I am calling this a win (32GB RAM, 1TB SSD installed). I hope this helps someone. I will do it again to fix the USB port alignment and the smudge on the camera.

Garry Colbert - Responder

Done and dusted, if your confident pulling things apart, something you can knock over in 2 hours from start to finish, mine took about 3 as I didn’t seat one of the sticks of RAM properly, luckily I was testing without the screen stick back down so was able to fix (but added another 45 mins to the process).

Guide is really really good for strip down, and not bad to follow for reassemble. Note about the Mic holes bottom of screen just right of centre, need to cut a gap in the adhesive to make way for the holes refer to —> Muffled Microphone - iMac 21.5" (mid 2017) - Following Adhesive Strips

Brilliant guide used this along with parts of the other guides here for 2017 Imac. Changed Sata drive to 2TB SSD and upgraded the factory 8GB to 32gb with 2x16GB Crucial Sodimm Modules (Part Number CT16G4SFS824A) which I can confirm work 100%. Whilst the Mac was in bits I also changed the PRAM Battery and had a general clean of fans etc etc. Makes sense to do it all when its apart as the less times you have to remove that screen the better! All in all took about 3 hours which also included 30 mins for finding where I had lost my isopropyl Alcohol too so as to be able to remove all the glue residue before refitting the screen. I would recommend buying the iMac opening tool, really does exactly what it says on the Tin and with the wheel being plastic It reduces the chance of damage to the edge of that screen but works extremely well in doing the job. If you are reading this and thinking of doing it then just make sure you have plenty of space so you can lay everything out in order as you remove it.
