    iMac Intel 21.5" Cardboard Service Wedge
    $4.99

    • 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.

    jerrid_foiles - crwdns2934203:0crwdne2934203:0

    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!

    “All iMacs also come with a traditional hard drive” mine doesn’t!! it’s HDD bay is completely empty, no SATA cable or anything. I guess I’ll have to upgrade the PCIe SSD instead.

    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.

    Phil Tesone - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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?

    arisnordico - crwdns2934203:0crwdne2934203:0

    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.

    pzhivulin - crwdns2934203:0crwdne2934203:0

    omg - forgot to switch the termal sensor from the old display...

    now fan runs like crazy...

    Andrei Balotescu -

    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.

    • Finish pushing the opening tool to the bottom of the right side of the display.

    • At this point, you'll want to run the tool back around the entire display, to ensure you cut as much adhesive as possible.

    Yes, do it many times to loosen the adhesive.

    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.

    Jeremy Brainard - crwdns2934203:0crwdne2934203:0

    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.

    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.

    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 - crwdns2934203:0crwdne2934203:0

    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?

    That's the part I ordered for mine and it seems to work ok. I did make a point of contacting the seller and advising them of my requirement and they ensured I got the right part and it matches the description of the link. Bear in mind I bear no responsibility if yours does not work since I am just sharing what I did and what I ordered. Thanks.

    Jim Stanford -

    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 - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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.

    Andrew Stephens - crwdns2934203:0crwdne2934203:0

    • 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.

    • 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.

    • Remove the following five Phillips screws holding the lower support bracket in place:

    • Four 3.2 mm screws

    • One 1.7 mm screw

    • On at least some EMC 2544 machines, all five screws are the same size.

    • You may need to peel up the display adhesive lining the bottom edge of the iMac enclosure to access the screws.

    I used the CR-V 4.0 standard screwdriver head to help peel away the adhesive lining. My fingers were too big to grab it, and my fingernails too short to get the removal started. This 4 screw head worked perfectly.

    Of all the parts of this entire procedure, replacing this one piece is the hardest part! The screws are tiny and they just don’t seem to want to grab the support piece. Also it seems to perform no function which is also annoying.

    Line up the screw holes and press on the bracket from the back to help the screws grab. If your fingers are too big, press with the flat side of your spudger. As long as there’s no gap between the bracket and the iMac’s frame, the screws should grab easily.

    If you only want to replace the HD and RAM, take a big shortcut and leave the logic board in, as well as all the parts needed to remove it (speaker, power supply etc). Once the display is removed, just take out the fan and the top two logic board screw. There is than sufficient space to gently remove and insert the two ram modules. HD can easily be replaced with an SSD by just removing the HD mounting brackets...

    • The next few steps bring your hands close to the exposed face of the power supply. Do not touch the face of the power supply or any of the exposed solder. Touching it risks a high voltage shock from the many large capacitors attached to the board.

    • Use the tip of a spudger to push each side of the power button cable connector and gently walk it out of its socket.

    I would advise that before removing the PSU unit and all other components from the bottom of the case that you remove the 5 screws at the bottom of the display which hold an insulation strip in place.

    The guide shows this piece removed, but does not tell you how to remove it.

    There will be 5, small J1000 screws. The middle one, which goes over Apple Logo is the shorter one of the 5, all others are the same length. Once this piece is gone removing the components is much easier, and chance of damage lessened.

    No need to remove power board and logic board and all other components, just remove the fan and it is quite "easily" accessable to change the RAM. Just need to use the tools to remove the old RAM and carefully install the new RAM.

    I just did it without removing the logic or power board

    Oleksandr Trokhymchuk - crwdns2934203:0crwdne2934203:0

    could you elaborate a little more, I would love to skip the rest of these steps. How did you accomplish this?

    ej P -

    Oleksandr Trokhymchuk,

    Thank you! You just saved me so much time! I wouldn’t call this “easy” but it saved me a lot of time and effort.

    Joshua Ericson -

    ej P: remove the fan assembly first. Then remove the connector that runs from the iSight camera to the logic board on the left.

    the RAM is located right near that cable. It’s tricky to remove but you can pop open the connectors with a black nylon stick and the RAM chip will pop up at 45 degrees. Make a mental note on which way you will need to install the new ram as it’s tough to see. For the Crucial memory I got it was label side facing away you (facing towards rear metal enclosure).

    the second chip has a plastic adhesive piece on it that you should probably attach to the new ram.

    remove both chips then install the new ram in sequence from the board out.

    Wizdom On Wheels - crwdns2934203:0crwdne2934203:0

    In the photo for Step 28, the power button cable connector is placed around the power board screw hole on the top left of the power board.

    However, on the iMac I upgraded, the power button cable connector was “fed” through the power power screw hole on the top left of the power board. The cable was too short to run around and below the hole.

    Hence, I had to ensure the cable was “fed” through the hole during re-assembly and the screw carefully screwed back through the hole.

    I guess every iMac is assembly just a bit differently, just to make repairs that much more fun.

    Tim Telcik - crwdns2934203:0crwdne2934203:0

    This is not correct and may have been assembled incorrectly during a previous repair.

    Charlie Nancarrow -

    Just replaced the hard drive and RAM with SSD and 16GB respectively and did NOT remove the power supply or logic board. Tricky is a word to describe putting the RAM in without removing the logic board. You work in the dark with little room to get your fingers in between the logic board and the back of the case. I put the first RAM chip in without a problem (the one next to the logic board), but the second to four tries and dropped it behind the logic board three times before finally getting it to position correctly. Just impossible to see and must work but feel. Still it was faster than removing all the components… though did remove the fan (needed cleaning anyway). All in all I can’t say enough about the help the guide was through the upgrade ! Thanks !

    Ray Burgard - crwdns2934203:0crwdne2934203:0

    I found this connector to be very tight and was afraid of breaking it off. I just kept slowly working on it—it did eventually come out.

    I did try to sneak the RAM in without removing the logic board but my fingers were too big. I found it too difficult and just continued on with this guide.

    Mikkif - crwdns2934203:0crwdne2934203:0

    I was not able to install the memory without removing all the components. My fingers are too big and I could barely get in that tight spot to swap out the memory. The hardest part about the power supply is that one connector under the chin next to the Apple logo. Once it is out, you are home free because it is so easy to plug it back in when you are putting it all back together again. Ridiculous that Apple did not put a simple access door behind those memory slots because they are on the backside of the Mac! They did an access door on the PowerBooks and it did not ruin the appearance. They could have designed a cool looking pop out door that only had a thin seam around it so it would still look good. Then you could remove the access door to upgrade the memory easily.

    Peter Hillman - crwdns2934203:0crwdne2934203:0

    Does anyone know if this is the same situation as in the 2017 model? I just changed RAM in the 2017 version and also skipped taking out the logic board. I just bent a pair of tweezers and put some tape around the tips to make them less scratchy and used them to place the RAM modules into the slots. Worked supereasy and much much quicker than performing the complete tear down of the whole machine.

    Nils Witte - crwdns2934203:0crwdne2934203:0

    @wizdomonwheels, I don’t see how I can get the RAM shield off of the logic board to access the RAM without removing the logic board. What am I missing?? I’m guessing that those of you that are suggesting this technique are working on older iMac models that don’t have the RAM shield.

    jiclark - crwdns2934203:0crwdne2934203:0

    Yes, you are correct. It is likely the various steps are a bit different on each model. If I recall I was likely working on a 2015 or older system. If there’s a shield in the way, I can’t think of a way you could get around it without pulling the logic board.

    • Rock the power supply forward and remove it from its recess in the rear enclosure.

    • Do not try to completely remove the power supply from the iMac yet—it is still connected to the logic board.

    • 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.

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

    • Squeeze the tab on the back side of the DC power cable connector and pull it straight out of its socket on the back of the logic board.

    when pulled the cable, even slightly, the actual female piece that connects to the logic board came off. am i screwed?

    Racheal Major - crwdns2934203:0crwdne2934203:0

    Repairing sockets that come off the logic board is possible, but very specialised work. Unless you have a magnifying lamp and the necessary desoldering and soldering skills, it will be difficult but not impossible.

    Charlie Nancarrow - crwdns2934203:0crwdne2934203:0

    The tab is at the far end of the connector, so you’ll need to reach farther than you might think.

    lkollar - crwdns2934203:0crwdne2934203:0

    When I pulled the disconnect, I pushed down on the disconnect, instead of pushing down on the tab on the disconnect and bent those pins… tried to straighten the bent pins and two of the pins broke off the logic board. Will I need a new logic board or can I purchase the pins…?

    Ray AA - crwdns2934203:0crwdne2934203:0

    I could not disconnect this cable without fear of breaking something (as previous posters did). I found that I could skip this and the next step by wrapping the power supply in a couple layers of a small towel (to prevent shorting with any other metal surfaces), and laying the power supply on the aluminum face of the iMac near the Apple logo. This got it out of the way enough to do what I needed on the logic board (changing PRAM battery) after completing removal of the other items in this guide.

    • 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 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 disconnect the input cable to the power supply. Because I had the machine lying on its back throughout, I placed it on to the metal bit at the bottom of the machine instead (with a cloth to stop the metal getting scratched). The AC inlet cable was pretty tricky to get un-locked, and the PSU sat on the case fine. It didn't hinder anything else throughout the guide.

    Dave Hallett - crwdns2934203:0crwdne2934203:0

    I thought from Dave’s comment that I could leave the power supply completely in place, but I was mistaken. In order to remove the hard drive assembly after you remove the center screw in it, you’ll need to at least unscrew it and the HD assembly will slip out. Like Dave said, you don’t need to unplug the AC or PSU, which I left hanging.

    Getting power supply to the logic board unplugged is also tricky without unscrewing the two bottom screws. They didn’t make this part easy.

    VauWeh - crwdns2934203:0crwdne2934203:0

    I would like to thanks Dave Hallett for his tip of not removing the AC inlet connector of the power supply. I simply wrapped the board in bubble wrap and taped to the iMac case, out of the way, thus giving access to the remaining disconnection procedures and preventing the board from scratching to the iMac case. It also made reassembly much simpler.

    Rob Hogan - crwdns2934203:0crwdne2934203:0

    Yeah, that AC inlet plug was a nasty one to unplug, mainly because I was trying not to bump the solder joints on the PSU. After a few wiggles and pulls while manipulating the spudger tool to release the clip, it finally unplugged. Made it easier by removing the PSU completely so you don’t have to worry about it. Don’t worry, plugging it back in is a breeze!

    Peter Hillman - crwdns2934203:0crwdne2934203:0

    With the right tool this plug comes out very easily. Forget about your tiny computer tools, go to the garage and grab a regular old needle nose pliers. Grab the clip and the plug at the same time. The plug will come right out.

    Carin Ann Loewen - crwdns2934203:0crwdne2934203:0

    Carin Ann— The most helpful comment on this procedure. After reading what you wrote I maneuvered the board, grabbed the clip with my left hand (a little awkward because of the cooling enclosure), squeezed the front of the plug, and got it out.

    Glen Kohler - crwdns2934203:0crwdne2934203:0

    • Lift the hard drive from the edge nearest the logic board and pull it slightly out of its recess.

    • The hard drive is attached by a single SATA power/data cable—do not attempt to fully remove it from the iMac yet.

    The newer drives have rubber ends and an adhesive side, be careful removing them if replacing the drive and be sure they are securely pushed back into the holder

    • 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.

    bstaud - crwdns2934203:0crwdne2934203:0

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

    jerrid_foiles -

    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!!

    jiclark - crwdns2934203:0crwdne2934203:0

    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.

    Marjie - crwdns2934203:0crwdne2934203:0

    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.

    • Remove the hard drive assembly from the iMac.

    When reassembling, I found it easier to loosen the HD tray screw from Step 48 and pull the tray outwards from the left side in order to plug the SATA cable in more easily.

    Anwar -

    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 - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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 - crwdns2934203:0crwdne2934203:0

    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.

    Jack OnFlickr - crwdns2934203:0crwdne2934203:0

    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!

    • Remove the hard drive tray.

    I am following these procedures for the following: iMac Retina 4K - 21.5" - 3GHz Quad Core - Radeon Pro 555 2GB - 4GB/4GB (8GB total - 2 slots) 2400MHz DDR4 SO-DIMM - Mid 2017 - Model: MNDY2LL/A - iMac18,2 - A1418 - 3069. In my case, the SATA cable is clipped into the bottom of the hard drive tray. Pull the hard drive tray up slightly and angle to reveal clips. SATA cable pops out from the side of each clip.

    iannai29 - crwdns2934203:0crwdne2934203:0

    Getting the two screws on the right side (next to the logic board) out and then back in was tricky, as they are recessed so much. To get them back in I used a magnet to magnetize my Torx bit (https://www.wikihow.com/Magnetize-a-Scre...) so it could hold onto the screws while I very, very carefully threaded them back into their respective holes.

    • When reinstalling the logic board, take care to align the exterior I/O ports correctly. The logic board can sit crooked even when secured with all its screws.

    • You can use a USB flash drive and/or ethernet cable to ensure the logic board is seated correctly while you screw it in.

    • Slightly lift the rightmost side of the SSD and firmly slide it straight out of its socket on the logic board.

    At this “Remove logic board” guide iMac Intel 21.5" EMC 2805 Logic Board Replacement step 65, I’m not seeing any PCIe socket. Does this mean if you bought an iMac with HDD you cannot add PCIe-based storage module to it later? I see in this guide, there can be a HDD with the PCIe-based model.

    If the iMac shipped with only a regular hard drive there will be no socket for a blade SSD.

There’s no PCIe slot on the EMC 2889 motherboard???

Lasse Wiinberg - crwdns2934203:0crwdne2934203:0

It depends!

If you got a SATA drive’d model then that is correct! No PCI/e SSD slot.

But! If you got a Fusion Drive’d model, or one which has a SSD then your logic board DOES have the PCIe SSD slot

Hi, for iMac 16.2 no Fusion Drive and no HD/SSD, there aren’t EMC for upgrade/repair? I’ve searched in all place, OWC Aura Pro 2X isn’t compatible with 16.1 and 16.2… I think this model can be only repaired or upgraded (maybe only repaired) in Apple Store. This is right? Best regards

Both the 2015 21.5” iMacs iMac16.1 & iMac16.2 (4k) offer a 8.0 GT/s PCIe x4 custom blade SSD connector on SSD only model as well as with the Fusion Drive model. A straight HDD system will not have the slot hardware!

The problem you are seeing here is the 21.5” A1418 only supported PCIe 2.0 x4 where the 27” A1419 supported PCIe 3.0 x4. The older SSD’s Apple used where PCIe 2.0 x2.

Apple didn’t use the PCIe 2.0 x4 SSD very long which is why you need to stick with the real Apple SSD in this series requires.

Can anyone tell me if the iMac 21.5” A1418 that came equipped with a 256GB PCIe 2.0 x4 (only) also has the needed cabling to add a regular 2.5" SATA-3 SSD? Thanks in advance for reply
