    iMac Intel 21.5" Cardboard Service Wedge
    $4.99
    Satın Al
    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.

    • 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.

    I have (21.5 inch, mid 2017, 2.3 ghz) base model same as this but not 4k. How much max ram can I install in my iMac??

    This guide contains many extra steps for what should be a straight forward, simple parts replacement without disturbing more than the display, left hand speaker and removal of 4 logic board screws for play. Nothing else except for the left hand speaker wire & iSight cable from logic board, the lower support bracket and loosening the speaker so as to move it around a bit.

    For the ram, I bent a pair of cheap tweezers long ago supplied with these replacement kits to the perfect angle for holding, locating and inserting the ram into the slots under the logic bd after moving each retainer w/spudger and popping out the old. Pay attention to the orientation of the ram when removing/inserting the ram! An automotive mirror is handy along with a small flashlight for closeups. Once the ram is aligned properly substitute your fingers for the tweezers, ease it into the slot, push up & engage! Reinstall screws and all else. I have done this job successfully this way countless times. For a tweezers pic contact me!

    Additionally, if a blade is present, I install the OSx system on the blade and everything else, apps and home folders on the new SSD. You get the very fast boot off of the blade and the full ssd for all else!

    • 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.

    • Be gentle! The glass may crack if pried too much. Use a hairdryer to heat the edges and loosen the tape if the room temperatures are low.

    • 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.

    • 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.

    • 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.

    • 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.

    Don't forget to place the mac face up on the table. Unlike older models, there is no more flap at the bottom holding the display in place. If you do these steps with the Mac upright, the screen will pop out, hit your table, and shatter :( Don't ask me how I know.

    So sorry. Thanks for that caution.

    Using suction cups (the ones that were made for removing the magnetic front glass on the 2011 and earlier iMacs) work well too. Place one in each top corner, while the Mac is lying face up on a table, and gently pull and it will separate the display from the main body. You might need to do a little more slicing around the edges if you did not get all the way through the first time with the roller. Then you can lift the display up at an angle to disconnect the cables.

    • 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".

    • 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.

    • Gently twist the card upward, slightly increasing the space between the display and frame.

    • As with the other side, twist slowly to allow the adhesive time to separate, and be careful not to over-stress the display glass.

    • 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.

    • While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.

    • 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").

    • 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 logic board.

    • Be sure to pull the display data cable connector straight out of its socket.

    • 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.

    There are pull tabs at each side off the bottom edge to allow easy release of the tape

    • 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.

    The roller tool for slicing open the display works great for this step. Get in there like using the card and roll across the bottom 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.

    • During reassembly, head over to our display adhesive guide to install the new adhesive.

    After removing the display, I also removed the 3 screws for the processor fan, disconnected the power connector for it and set the fan shroud aside. Disconnecting the remaining cable (similar style to 1 of the cables for the display) that is in the way of the RAM chips is all that's left to do. I was then able to access and quickly remove the two Apple-provided RAM chips, and replace them with 3rd party RAM. Turning the iMac on its side, so that it's in a position where you're physically putting the RAM chips DOWNWARD into their respective slots is the best way to go about uninstalling and reinstalling the chips. Using a narrow but long'ish plastic spudger tool is the best way to defeat the spring-tabs which hold the RAM chips in place. After removing the LCD display, changing the RAM is about a 10 minute process!! And I'd SURE prefer not to remove all the parts and risk damage to the iMac via the standard procedure listed. As per usual, take your time and work gently :-)

    Teardown the whole machine just to change RAM? While preparing to comment on this procedure I just noticed the comment made by Mitch K above. I ran pretty much the same procedure that he describes this afternoon (steps 1-23, 43-45, and step 55). Then I swapped out the original 2x4GB RAM chips for 2x8GB chips by reaching behind the logic board, releasing the spring retaining clips one chip at a time (starting with the chip further away from the logic board), pivoting the RAM towards the back of the machine, and then carefully sliding it out of the slot. I easily slid in the new chips and then pivoted them to lock them down. No hassle, no time lost. As Mitch K states above, not only is this “shortcut” method much quicker and easier, but it provides less risk of damaging cables, sockets and other delicate components during a total teardown. Why mess with the power supply board just to change RAM? I do not advise to follow the current iFixit.com procedure written by Sam Lionheart, regardless of user skill-level.

    nycsandor - Yanıt

    THAT sounds one !&&* of a lot easier than the full tear down. I wonder if there’s a video of the process described by Mitch K? Adding that to these verbal instructions would really help relieve the apprehension and anxiety around the process! I do sometimes find the additional warnings, though appreciated from a “safety first” perspective, are somewhat overstated. It’s been a very long time since I shorted out RAM, or fried a PCB, or broke a connector, regardless of how finicky, fragile or awkwardly designed and positioned. I may have WANTED to break something, and the air might be blue for a few seconds, but inevitably, things go back together, the start button gets pressed, the startup chime sounds, and we’re in business. Practice DOES make as close to perfect we are likely to get.

    bruce - Yanıt

    Mitch has the exact method that works a treat. You don’t need to follow steps 24-37 and also 40-63. Step 51 is the step to remove the camera cable and is needed. Steps 38 and 39 are for the Fan. That is all that is needed. Done quite a few like this.

    Be careful not to drop the RAM down the back of the logic board!

    By NOT removing all the other stuff you can avoid either damaging it or forgetting to plug in a cable.

    Charlie Nancarrow - Yanıt

    I just trued this shortcut and it was not successful. I was not able to seat both RAM chips with this shortcut, and managed to slightly damage one of the retainer clips. I simply could not manipulate the chips into and out of the slots effectively without taking everything apart as described in the full set of steps.. I ended up retracing my steps and following the entire procedure, carefully, and that worked without incident. So, bottomline, it is definitely more work to follow all the steps but from my experience, it is decidedly safer. Your mileage may, of course, vary. It was successful in the end, and I swapped out the hard drive with an ssd during the same procedure and my machine is very, very much faster.

    jan - Yanıt

    I have completed by following the Mitch K post and it is much easier than stripping down the whole thing, just be aware that to remove and replace the ram chips means working in a tight space, you need slim fingers and don’t be tempted to use force, take your time.

    Barrie Price - Yanıt

    Well, I have slim fingers, but they are 60 years old, and they don’t work like they used to! LOL.

    Jan Hogle -

    Agree with Mitch K’s procedure. The only added tip I would throw in is to use two 45 degree tweezers with their plastic covers still installed to easily pop loose the RAM. I couldn’t get the plastic spudger tool to work myself, but the tweezers easily reach the RAM clips. Just make sure the plastic covers are installed and you won’t be in danger of scratching or shorting anything out.

    charlesnick - Yanıt

    So thankful I discovered these comments. Saved me a TON of time! Thank you!!

    Adam Roberts - Yanıt

    These comments were very useful. Thank you. I just needed to modify a pair of tweezers to allow me to seat the new RAM more easily. The ifixit screwdriver wasn't able to turn some of the screws as they were installed too tightly, and I didn't want to wait to order and reveive a pair of right angled Torx screwdrivers that would give me more leverage to get those boards off.

    • 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.

    I left mine out. LOL

    jerrid_foiles -

    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.

    I put it in at a slight angle lining up the right hand side holes, screwed in the two screws and gently pressed my finger behind it on the rest

    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...

    • Use a spudger to loosen the right speaker cable's connector from its socket on the logic board.

    • It is useful to push downward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    • Pull the connector downwards to remove it from its socket.

    I highly recommend doing steps 27 and 28 first and then pull out the cable. It will give you more room on the right side of the cable to work with making this step that much easier.

    Eddie de la Rosa - Yanıt

    The two corners of the connector are latches that need to be pushed toward the center of the connector to release. This is easily done with the pointed end of the spudger. Once the two corner latches are released, the connector comes apart easily.

    • 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 top of the power supply towards you to access the DC power cable connection behind the logic board.

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

    what happens if you damage the power socket on the logic board?

    The tab is on the bottom of the connector. You can’t see it. Squeeze the bottom of the connector close to the cables to properly release tab. Pulling straight out is important.

    In the photo above, the index finger is shown squeezing the connector locking tab. Do this while using the flat end of a spudger to release the latch. Once the connector is moved about an eigth of an inch the latch is released and the connector should come out freely.

    The key is to squeeze the tab in the part near the cables. You won’t feel like the tab is moving, but squeezing it there is necessary to get it out.

    • Push on each side of the left speaker cable connector with the tip of a spudger and gently "walk" it out of its socket.

    As noted in the right speaker cable section, the two corners of the connector are latches that need to be pushed toward the center of the connector to release. This is easily done with the pointed end of the spudger. Once the two corner latches are released, the connector comes apart easily.

    I broke off one of the antenna connectors when I took off the antenna wires, but the new 802.11ac card is working:) I seems the way to take off the wires is lifting it up from the wire side. In hindsight I just wasn´t careful enough.

    If you have a pair of angled tweezers, they work well for grabbing under the connector so that you aren’t pulling on the wire. The head of the T10 screwdriver works well for pressing them back on.

    On some models there is a tiny microphone cable connector, just above the lower left logic board screw. Remove by carefully pulling straight down. There is also a piece of insulating plastic w/adhesive on top of the screw which can be pulled off prior to removal. Save and reuse with the same screw on installation.

    Was the iMac have a fusion drive? I´ve just read that 21,5" iMacs without Fusion Drive or SSD don´t have the PCI-e slot activated. Could you confirm please?

    Daniel Calderazzo -

    @danielcalde2053 - A HDD only system won’t have the connector or added circuitry to support the Blade SSD. With that said people have altered systems! Taking out the wimpy Fusion Drive cache SSD as they often fail. So you might find a HDD system with a working slot!

    Dan -

    Read somewhere that a certain type of adapter is needed to use a "Samsung 970 EVO Plus NVMe M.2" in either a 21.5" or 27" 2017 iMac. Does anyone (most likely @danj ) know if it will work?

    Long term goal...have both sizes of 2017 iMacs. Plan is to install a faster i7 cpu in 27" and migrate 3.4 GHz i5 to 21.5" to replace 3.0 GHz i5 in 21.5". While inside 27", will replace fusion drive with the EVO plus and perhaps had a larger 7200 rpm HD or perhaps a 2.5" SSD.

    While inside 21.5", i plan to upsize SSD from 500 Gb to 1 or 2 Tb. Not sure which ssd form factor is currently inside but i believe it is a 2.5". Does anyone know if there is a drive cavity in a 2017 21.5" iMac to fit a full size HD (to possibly use a stacked pair of notebook size SSDs?

    Thanks to all in advance!

    mbed - Yanıt

    I really don’t recommend using M.2 SSDs in iMacs as they are a bear to open up to get to the SSD socket and many adapters/SSD sets are flaky!

    If this is a system which has important work I would stick with either an Apple or OWC bade SSD. Yes, I know! You want something with more performance. Sometimes it doesn’t pay 😖I had wished Apple would have gone with the standards based M.2 SSD’s their greed set the course! The rub is Apple has other lines in their SSD’s these adapters and M.2 SSD’s don’t offer which will bite you when your drive gets full as the wear-leveling and housekeep functions use these lines.

    As far as Samsung 970 EVO Plus drives you will need to update its firmware as they did have a few interoperability issues with macOS when used in MacBook Pro’s

    Dan -

    @danj I did get this blade SSD from OWC and it is working fine. My wife only uses this for non mission critical work now since she has a 16" MBP, but it sure beats the pants off of the old HD that shipped with the system. :-)

It is a special blade SATA drive, essentially just a SATA SSD with special connector. Same form factor as in 2012-2013 MacBook Pro Retinas. You can install a normal M2 SATA (not NVMe!), but with an adapter

Remember guys: the base model that did not ship with SSD is completely missing the M.2 connection soldered on the board from the factory, and will not be able to mount one. The main HDD can still be swapped for one though.

I have an iMac 21.5 Late 2012 (2.7GHz i5) and I was thrilled to find a vacant Apple SSD slot!

I have since installed an SSD and I am creating a Time Machine backup.

Also really nice to know the RAM can be upgraded to 16GB at some point :)

At first glance I was sure this iMac would not be upgradeable but it just goes to show, you should always physically check!

“The initial production of the base model for the 21.5" iMac didn't come with a slot for the SSD. Later production models included the SSD slot, but there's no way to determine if the 2012 21.5" iMac with a 2.7GHz processor has the SSD slot without opening it up to see if it's available.
