    • 힌지가 자유롭게 움직이면 iMac의 균형이 맞지 않아 작업하기 어렵습니다. iMac을 눕힌 상태로 수리를 완료할 수 있지만, iMac 서비스 쐐기를 사용하면 더 빠르고 쉽게 수리할 수 있습니다.

    • iFixit 카드보드 서비스 쐐기를 사용하는 경우 다음 조립 지침을 따라 조립하세요.

    • iMac에서 작업을 시작하기 전에: 컴퓨터의 플러그를 뽑고 전원 버튼을 10초 동안 길게 눌러서 전원 장치의 커패시터를 방전하세요.

    • 전원 장치 뒷면의 커패시터 리드 또는 노출된 납땜 접합부를 만지지 않도록 각별히 주의하세요. 보드의 가장자리만 잡으세요.

    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??

    Narendra Verma - 답글

    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!

    • 디스플레이 왼쪽의 전원 버튼 근처에서 시작하여 유리 패널과 후면 인클로저 사이의 틈에 iMac 여는 도구를 끼우세요.

    • iMac 여는 도구의 허브가 휠을 너무 멀리 밀어 넣는 것을 방지합니다. 다른 도구를 사용한다면 디스플레이에 3/8" 이하로 끼우세요. 아니면 안테나 케이블이 끊어져 심각한 손상을 입힐 위험이 있습니다.

    • 살살 다루세요! 너무 세게 비집으면 유리에 금이 갈 수 있습니다. 실내 온도가 낮은 경우 헤어 드라이어를 사용하여 가장자리를 가열하고 테이프를 느슨하게 하세요.

    • 3/8" 이상 끼우지 않도록 주의하세요. 아니면 내부 부품을 손상할 수 있습니다.

    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.

    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.

    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 :-)

    Mitch K - 답글

    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 - 답글

    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 - 답글

    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 - 답글

    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 - 답글

    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 - 답글

    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 - 답글

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

    Adam Roberts - 답글

    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.

    What’s the trick to connect the SATA cable to the disk?? There’s very little play in the connector. Am unable to position it properly to get a connection. Maybe my fingers are too large.

    Paul - 답글

    Paul, you would have to get a external case inclosure to install the drive into. There are USB and SATA versions.

    B Jack - 답글

    Since I unplugged a SATA cord to remove, will I need a SATA case? Gonna connect to new 24” iMac (M1) and try and grab the pics and music.

    Paul -

    The IFIXIT kit I bought included a SATA case, which I used to pull the data off the old hard drive which was on its last legs. Thank you, IFIXIT!

    This was my first attempt at opening an iMac for anything but RAM upgrade (when it was possible easily on older iMacs). I too took it easy and slow. Replacing the hard drive was the easiest part of all this! The hardest part, which I'm still struggling with, was unplugging and replugging the display data and power cables. I was able to install an OS on the new SSD but in order to close the machine I had to unplug the display cables, and it seems that one of them did not seat properly, since the computer starts up but the display is black. Sigh. I will have to do the cutting and pasting of the glue strips all over again. Apple really doesn't want us doing these repairs.

I used the iMac Opening Tool just as shown in this guide to separate the tape. DISASTER! The screen cracked! I used the tool slowly and carefully and despite this, the screen cracked. I should have simply used a guitar pick. That said, while I was inside my iMac replacing the Harddisk with a SSD, which was pretty easy to do, I decided to also see if I could replaced the 8GB RAM with 16GB RAM WITHOUT removing the logic board, as shown in other instructions on this site. I found that by simply removing the fan assembly, this makes enough room to reach behind the logic board and unclip the 2 memory modules. I installed 2 8GB modules (1600MHz DDR3L SO-DIMM PC12800 204 Pin) without much trouble. I used a plastic stick to reach behind the logic board and unclip the existing memory modules, then carefully inserted the new ones and clipped them into place. This is much easier than removing the power supply and logic board and all of the associated connectors and screws.

I had to replace the HD as it failed after less than two years. It was a good opportunity to increase the RAM from 8 to 16 GB. So I ordered the RAM chips from Kingston and a 256 GB SSD from Angelbird.

The repair went smoothly: to anyone trying this, please carefully follow the iFixit step-by-step guide. I recommend reading at least twice the whole procedure *before* beginning. Check all the photos. During the operation itself, I had the guide open before my eyes on my iPad and followed it step by step. The opening tool is a bit fragile, the wheel got damaged after the operation, but I guess it was designed to be used only once. After all, the adhesive strips can also be used only once!

For those replacing the hard-disk with an SSD: I highly recommend the Angelbird model "SSD wrk for Mac" (http://www.angelbird.com/en/prod/ssd-wrk...), for several dollars more you spare yourself the need to use additional software to enable TRIM or persuade the fans of your Mac that the HD's temperature is Ok.

Hi! Thanks for the tip! Do you know if can I put an SSD on an imac 21.5 in late 2012 ?

Tania Diego -

after changing the hard drive the monitor no longer works. Apple won't fix it because I opened it, and third-part wants to charge me $300-500. Hope you guys have better luck!

Very simple so long as you take your time. I had the benefit of an on site screen replacement so could see what the tech did. A few tips inc links to photos.

1. Use a marker to draw a line on the plastic card so you can see the max depth.

2. Use sticky tape either side of Apple logo on the front of the iMac, you can then position and rest the screen on the lower ledge in the right place, hold with the tape (don't remove the adhesive backing tape at this stage). The tape then acts as a hinge so screen can be lowered and raised to refit connectors and remove backing tape. More tape at top will allow you to trial fit and test prior to sealing the screen back on. It's what the Applecare tech did when he changed the screen!!

3. Be careful when removing old adhesive. Screen has a black plastic type backing to it (this forms the black frame that you see from the front) and is easy to peel and damage.

Good input. I just ordered the strips to swap my HD with a SSD. I've tested i via USB but it keeps getting corrupted, second SSD too and people say it's the fact that I'm running it via USB. So now I'm ready for the big step and actually taking apart my iMac :)

Tape seems like an excellent idea. What's that silvery tape you used?

Daniel Mores -

Excellent guide and parts. My late 2012 iMac hard drive failed. As a side note, it passed SMART and Apple Diagnostics but was extremely slow - only about 5 MB/s transfer. In the logs I would occasionally see ioError but rarely.


I bought a new Retina iMac before attempting to fix this one. I'm a retired programmer and fixed computers all the time when I was young and could see better. So I was a little apprehensive about doing this but it went off without a glitch.


finepics comment and images above was helpful. Not mentioned was you need to clean off the adhesive from both the display and the iMac body. I wasn't sure if the black stuff on the display was supposed to stay as a mask but researching tech notes elsewhere said to remove it and that was correct.


Thanks so much to ifixit! I'm a long way from an Apple Store so this saved a lot of inconvenience as well as money. I bought an SSD to replace hard drive and that was less than just the labor from Apple.

steveo - 답글

This was a very straightforward repair and a lot easier than I imagined. I'm coming from a background of working on iPhones & iPads, this was a breeze in comparison. It took me only a few minutes to open it with the recommended tools. The adhesive was really easy to remove and replace as well. I could probably do the next one in less than half an hour from start to finish (excluding the time it takes to install the OS). Thank you for this guide!

My recommendation for anyone trying this, buy the service wedge. If it's your own iMac, it's definitely worth it if you need to open it up again. If you're in the repair business, it's a no-brainer. It tilts and holds the iMac at the perfect position to repair the device and the perfect position to lay the screen on the iMac before you seal it up.

jacob - 답글

I replaced the hard drive following the guide and used the adhesive strips which are a must.

You DO NEED to be very careful with the step of the "credit card" used to separate the screen from the frame.

Make sure to design a reference line on the card in order to avoid to push it too far inside the frame and risk to damage the screen connections. Many users failed to perform this part of the repair procedure and had to replace the screen itself.

Patrick Putignano - 답글

I followed this perfect guide and I replaced the HD with a SSD of Kingston. The iMac comes on because you hear the usual "going" but the screen remains black. I tried to connect an external monitor and is the same black. What may have happened?

Same here, I replaced Samsung Evo 850 SSD, I can hear the start sound but it never show the Apple logo. The screen remains black.

Will I have fan problems replacing my HD with an Samsung Evo 850 SSD on my iMac 2012 21.5?

I don't plan on installing fan software. Will this be a problem?

What fan is the one people are saying will run faster? CPU fan?

Will a 2.5 SSD fit fine?

filettransfer - 답글

Working on an iMac is a lot like working on a laptop. This is an awesome guide, but if you've never done it before it's not a good starter project.

Ian Armstrong - 답글

Changed the horribly slow original hardrive to a Samsung 850 EVO SSD. Used the opening tool and the cards and everything went very well. Just be sure to follow the instructions very carefully and make sure you buy the adhesive stripes for the reassamble. I also added some extra RAM while opening the machine. I added an extra 8 GB from Crucial (1600MHz DDR3L SO-DIMM PC12800 204 Pin) so now I have 12 GB and that is enough for me. I did as stated above and removed the fan and then you can remove the RAM if you are very carefully. If you do as I did and upgrade only one of slots, one of the slots is very easy to reach. While being inside the machine I also carefully vacuumed the inside since there were som dust in there. My iMac now feels as good as new and is so much faster so the upgrade was well worth it.

Super easy to remove the LCD.

I use a utility knife and slow and carefully go around the LCD (1/4" deep). You can feel the tension as you move it along, so just go through it until the knife blade past every gap smoothly. Just keep going through it until all adhesive is loose and I mean ALL adhesive. At the end the knife should go along the LCD gap without any tension. At that point, just lift it up as described above. It should be so smooth that it feels there's no adhesive at all.

Je viens de réaliser le changement de mon ancien DD par un SSD Samsung 850 Pro de 512Go, juste impressionnant, tout va plus vite!

C’était la première fois que je démontais un ordi, en étant très précautionneux et en suivant le tutoriel à la lettre, aucun souci. Pour le double face, j’ai mis un 3M standard de 6mm de largeur, ça convient parfaitement.

Avant la manip, j’ai utilisé Carbon Copy Cloner en version d’évaluation juste le temps du changement. J’ai retrouvé tout mon environnement après l’installation.

Juste un petit souci sur Microsoft Office qu’il faut réactiver sur le nouveau disque.

No mention of the extra cable needed for temperature control? Is it no longer required?

Walter Poole - 답글

I do not believe the thermal sensor is required.I recently replaced my old HDD with the Samsung EVO 850 2TB SSD. The HDD was failing and taking 15+ minutes to boot. Not really sure if this had to do with age (6 years old, bought new) or with the fact that my drive had been partitioned; as I have read that some people have had their drives fail early due to partitioning. Regardless, the process was relatively pain-free, and have not had the issue with my fan running at full speed (runs at normal fan speed between 1200-1300 rpm’s). Computer feels brand new, and is now booting from restart in under 12 seconds. This website rocks!

Great guide, thanks!

tedcmacdonald - 답글

bah this is way over complicated, take an exacto knife, put it out one or two clicks, cut off the adhesive, use a playing card or whatever if you need spacers to keep it from resealing, when you seal it back up get some strong velcro tape so you can get back into it later if you need to. If you can start at the camera since there’s no adhesive above it and pull away from it so you don’t scratch it, don’t cut the bottom it will act as a hinge and just come right off after disconnecting the cables. It’s not possible to cut any wires around the edges because there are no wires around the edges unless you go three inches deep.

su’ un imac 2012 sostituendo l’hard disk con un ssd ci sono problemi con i sensori o le ventole vanno al massino?grazie

Francesco - 답글

I completed this today and it was easier than I had imagined. I have replaced the drives in around 30 of the older iMacs and I was a little annoyed about the screen removal process for this one (which is my daughter’s one)! I couldn’t find a use for the service wedge…

The hardest thing was getting the SATA cable back in, I ended up removing the rubber casing from the new drive and then plugging it in, there was more room and with the help of a spludger it was easy - I then eased the cover back on. I used an intel 545S series 512GB SSD.

My advice when following this guide is to take your time with the iMac opening tool and cards (and mark 3/8 inch on the card with pen) and if you can find an extra pair of hands then that’s good too. I had some help so we didn’t need to completely remove the screen, it just tilted back quite nicely. I didn’t need to worry about replacing the adhesive strips in the hinge area either.

The screen data and power cables were easy to manage.

Thanks!

How come there is no mention about using a sensor cable, other sites such as OWC recomend using it for fan control? And also sell one! I remember doing a ssd instal with out it but had to use a fan control software to not make it go crazy, some more detailed info about this would be nice no ? Thanks

Thank you for this guide, i‘ve done the instructions very carefully and slowly, not in one hour, but all is ok now, a new 2TB SSD does now what the old 1TB HDD done before( Smart says defect) . Now it runs much faster as it was a new iMac I think

The guide gave me all the information I needed to replace a dead drive. I purchased the tools I didn’t already have and the supplies such as the adhesive strips from iFixit. I kept the guide open on my laptop as I worked through the repair. Here are a few tips:

• The toughest adhesive strip to remove was on the lower left of the housing near the power button, where people grasp the Mac to turn it on.

• When the Mac was on the table with the screen facing up it was helpful to put something heavy behind the base so that it wouldn’t slide as I disconnected and reconnected the wiring. A no-skid pad would work, but I didn’t have one handy.

• The guide doesn’t mention them, but a couple of heavy-duty suction cup handles are handy for manipulating the screen. Not essential, but nice to have.

• Don’t rush! Read and understand the guide before you start, make sure you have all of the tools and materials and work slowly and carefully. Patience will be rewarded by success, impatience by problems.

i’v just replace my RAM from 8 to 16GB and my HD with a SSD, thank you for the tutorial ! it really help

i had an issue to restore my data from my Time Machine backup because my mac load the mac tool from OSX LION and my backup was on OSX Catalina. A good thinks to note before proceeding is to create a usb key launcher from your system :

I just replaced the hard drive on a late 21.5 inch iMac with a 1TB SSD using the kit from iFixit. Easier to do than I thought. I was really worried about breaking the glass. Key is to have a 2nd person to help keep it open while you are disconnecting and reconnecting the cables going to the monitor.

I also highly suggest not putting on the adhesive strips on until you are sure everything is working, i.e. temporary put the display back on and hold it in place with some masking tape, boot it up, and if it works, take the monitor back off and then apply the adhesive strips.

One final note…when I did boot the iMac up with the new SSD in it, it shows two separate drives…. the 128 GB SSD (the part left over from the fusion drive) and the new SSD. So, I am guessing I could have gotten by just buying the tools and not replacing the HD and just attaching an external HD for storage if needed. Oh well. I even cloned the fusion to the new SSD but I guess I didn’t need to. Ended up booting in Recovery mode and reinstalling everything.

That cutter works great, btw!

Tony Padgett - 답글

Hi Tony,

Just wanted to know what procedure you took before replacing the HD example, did you do a backup on time machine?

and after the upgrade how did you boot up without an operating system? because the OS went with the old HD you removed right?

and what did you do with the old HD?

The upgrade kit comes with an external HD but no info what to do with it. I mean am I supposed to back everything up on it

before I do the upgrade? I already have time machine backup.

Cheers mate

Steve

Sam and friends, I was able to follow this guide and replace a 1TB original Hitachi drive with a Samsung 1TB SSD. Cloning the drive with MacOS Disk Utility was the first step. I ordered the recommended parts from iFixit, including adhesive strips and followed all the steps. Then I went reverse the steps as this article says. Then, OOPS! I had to backtrack to apply the new adhesive strips. But I did it, a really a complicated job for a first-time with iMacs. Super write-up with excellent photos. Apple designs EVERYTHING to be difficult to repair!
