    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, 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.

    This instruction page is not clear and is ambiguous if you have to do all the steps to just change the power supply please clarify another words do I have to remove the speaker and the hard drive to replace the power supply?

    • Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case.

    • The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" (9.5 mm) into the display. You risk severing antenna cables and causing serious damage.

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

    Clark Green - Ответить

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

    Dan -

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

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

    Walter Hayden - Ответить

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

    Walter Hayden - Ответить

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

    Benon Koebsch -

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

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

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

    Anthony Zimmerman - Ответить

    Don’t know if you are still around, but THANK YOU for posting this video! The video made it seem SO NOT SCARY and, in conjunction with the photos and comments and tips on this guide, was a lifesaver. Big thumbs up.

    Melissa Ortiz -

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

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

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

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

    Carlos Ferrari - Ответить

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

    Depple - Ответить

    NOTE: I followed every step word for word, but the adhesive strips supplied are as bad as double sided tape. Within 48hours the screen had slipped off and cracked. Now I need to fork out for a new screen and try again.

    Not sure what to try next time with strips? Perhaps a bit of glue to help hold it??

    Dan Kelly - Ответить

    Where do i get the “iMac Opening Tool?” its neither in the list of tools nor could i find it on the tool page.

    Patrick Cella - Ответить

    Hi @snappadoodle! The opening tool is included in the adhesive kit included in the tool list, but you can purchase it separately here.

    Sam Goldheart -

    After disconnecting the power cord and before cutting the panel adhesive, push and hold the power button for 10 seconds. This will discharge the power supply capacitors. In case you accidentally touch the solder joints on the board, you won't be shocked and drop the panel.

    Bottom line: This repair seems to have worked (so far no more intermittent shut-downs). Thanks iFixit!

    As a novice who fully expected to destroy the display or worse, I make the following recommendations: (1) Before you start, read the steps several (many) times; visualize doing them and imagine how things could go wrong; (2) Read all the comments—there were some really helpful tips—like simply displacing the left speaker rather than fully removing it; (3) Get the recommended tools*; and (4) take your time—if you start to feel frustrated—seriously, stop and take a calming breath. Time is your friend. Failure is not an option.

    *I would add a 3-prong parts puller to the tool list—it’s great for pulling and starting loose screws so you don’t drop them down into the chassis like I did. It’s also great for retrieving the screws you’ve dropped into the chassis.

    Brad Bauknecht - Ответить

    Hi brad, what exactly did you repair to stop the shutdowns? I’m having the same issue

    merinian -

    Merinian: I replaced the power supply and it’s still working fine at this late date. No more intermittent shut-downs. Fingers still crossed!

    Brad Bauknecht -

    Just completed the Core i5 to i7 CPU upgrade and can strongly recommend getting the “pizza tool” to cut the display adhesive. It worked flawlessly and was done in less than 5 minutes. No inadvertent cables cut. No display problems.

    Thank you very much for the instructive tutorial. I just successfully replaced the hard drive on my 2012 iMac 27. I used a disposable surgical scalpel 15 blade, and locked the blade extending 9 mm from the scalpel shaft using office tape. I used regular double sided tape to reattach the screen. I cut the strips using the scalpel. I have no previous computer experience and this is the first time I replaced a computer part. This was easy and fun.

    Filip Dolatowski - Ответить

    You are very lucky! I’ve had three systems come in which someone did the exact same thing! All three cut the display ribbon cables. Please don’t use surgical knifes or any other knife! Use the proper tool the special pizza cutter wheel designed for the task.

    .

    You likely spent more on the knifes than what the wheel cost with the correct tapes. You make the next time doubly hard to open not using the correct tapes! Hows the built in microphone? You may have messed it up.

    Dan -

    Thank you very much for the tutorial. You are the best!

    After reading all the post here I almost gave up doing this on my own. But I did it anyway and was succesful. I would recommend everyone to use the rollcutter. There is no risk of harming the screen if you use it. And in my case it was enough to open the imac. If you do not harm the screen connector or the screen the biggest part is done. It gets easier once you`ve stacked your screen somewhere safe. The parts inside are mostely not as delicate as the heavy and expensive screen!

    Take your time and work carefully. It is definitely doable!

    CONSULTINEL - Ответить

    I found the cutter tool that came with my kit to work just fine. The wheel is extremely thin and I had no problem inserting the wheel to begin cutting. I follow the guide for the most part but took my time and use the cutting wheel slowly and then repeated the process a few times. Once I was able to pry the screen back about an inch I used the other end of the tool to cut additional adhesive that was still clinging to the body of the iMac and the screen. Having just replaced the power supply, and having my iMac running again, I do not think I will use the adhesive strips to reattach the screen. The screen fit back in place no problem which I did to test my Mac. Because the iMac screen sits at an angle I am quite comfortable that the screen is not gonna fall off. Also while having a screen off I was able to clean the inside of the Mac of dust buildup. I think I will only use the adhesive strips down the road if I’m gonna sell the Mac, which means I can give it a good clean before securing the screen.

    James Orwin - Ответить

    If the screen falls off (which it will do!) it will damage the parts which would be a lot more expensive! PLEASE get the correct tapes and properly mount the screen back on.

    Think of it this way how many people have shot them selves with a gun not realizing it was loaded or set to go off!

    Dan -

    I think Dan is right as I decided it best to complete the process with the adhesive tapes to secure the screen. I just took some time to do a complete clean of the interior before sealing the display.

    James Orwin - Ответить

    Ordered the full kit to replace my busted 3TB disc hard drive. All the tools work and are excellent. These pictorial and instructional install videos are complete, easy to use, and have good imagery. The 2TB SSD installed exactly as depicted. I used some 3M double sided automotive emblem tape to stick adapter to iMac case, no probs there. The adhesive strips also worked fine and stick firmly. Screen is solidly mounted, no falling out here. IFixit is awesome and this kit saved my over $1200 in getting another iMac. Highly recommended.

    • Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

    • Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.

    • Run the tool up along the left side of the display.

    I found the 'pizza cutter' surprisingly smooth at cutting through four-year-old adhesive.

    Gerry - Ответить

    In my experience the cutter also worked very well for cutting the original adhesive. Unfortunately when I was reinstalling the display with the new adhesive strips, somehow the display power connector came loose. I had to open the display a second time and the cutter was not as effective against the new adhesive. I managed to break the cutter tool plastic wheel and cause a few small cracks in the edge of the displays glass as I worked! Be careful and go slowly!

    azaadkb - Ответить

    The cutting tool worked great until I accidentally twisted it a bit while rounding a corner. A chunk of the wheel snapped off, making the rest of the job quite a bit more challenging. Just make sure you are keeping the tool directly parallel with the screen.

    BARRY RODRIGUEZ - Ответить

    I concur, opening the screen a 2nd time is considerably more difficult because the adhesive strips are thinner than the original, which makes getting the cutting tool inserted much more difficult….as a result unknowingly I elongated a small crack to a much longer crack and somehow, the LCD now has a wide grey strip from top to bottom….The first time opening was easy, second time resulted in a ruined screen.. The cost of. a replacement LCD is the same has replacing the entire computer….I would recommend anyone attempting to remove the screen for any reason, do not use the aftermarket adhesive strips if you ever intend to open it up; again, or cut the strips much shorter, or possibly use a few pieces of scotch tape or similar to hold the screen in place….since the screen tilts back, this should not be a problem…Good luck…

    • Cut the adhesive along the top left of the display.

    The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

    • 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.

    what about the part where the camera is though? do I just treat it like the rest of the screen?

    Boris - Ответить

    yes. the tool can’t go too deep

    flow in - Ответить

    I measured a depth several positions.

    - About 6 centimeters near iSight Camera center, you must no use iMac opening tool, because iSight element exists.

    - iMac opening tool has a 9mm radius, so it may break iSight camera element.

    - Making a plastic card stacking 2 or 3 to 3mm, under the iMac opening tool, that makes inserting a gap 5~6mm like below.

    @. iMac opening tool

    ====== plastic card3 (credit card 1mm)

    ====== plastic card2 (1mm)

    ====== platic card1. (1mm)

    ———————————————— isight camera element (total 5~6cm) ————

    In my case, i got a display problem where lcd display yellow connector was torn without care.

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

    I didn’t have the fancy cutter or cards. So I used my actual pizza cutter. Followed directions just the same, and it easily cut through the adhesive w/o issues or marring the surfaces. Actually used it to rock back and forth to lift the screen. It’s all about taking your time. I rolled it back and further until cut thru. The 3/8 to 1/4 inch is right, but the screen framing actually prevents further depth unless you force it further. The adhesive actually protected the glass while cutting thru, so no damage. Great instructions, but where to get the replacement adhesive to reinstall?? Should be four independent strips.

    Keith Thomas - Ответить

    You are very lucky you didn't cut to deep! The plastic cutter that's in the kit is the only thing I would use. Spending a few bucks on a tool is a lot cheaper than $500 for a new display!

    Please don't use a real pizza cutter!

    • While the opening tool did the lion's share of the work, 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, insert a plastic card between the display and frame.

    • Be careful not to insert it more than 3/8" (9.5 mm), or you may damage internal components.

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

    Peter Fischer - Ответить

    Same thing with me…. Pushed cards to far…. new panel needed…€600…..

    i think ifixit needs to place a bigger caveat, as I have missed it the first time

    i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

    Eugene Kharkov - Ответить

    I broke one too. And even if you think you did it correctly, you’ll not be able to see where you might have gone too far. You would think it’s very protected behind that metal plate, but no. Take special care with this offence to “right to repair” This should have been designed WAY better. I mean replacing a hardrive that is very likely to fail over the course of time, or even a simple desire to upgrade to an ssd!.

    HINT: If you turn the card and use the blue part of it, then you can avoid going to deep: no further then the blue part …

    Barthold - Ответить

    On the cards I got with my iFixit kit, the blue part was way bigger than 9.5mm — closer to 20mm!

    I made a line 9mm from the edge of each of my cards and used that as a guide.

    Damian Chadwick -

    I’m thinking I might just use vinyl tape to keep the screen in place for at least a little while after an upgrade. The extra strength of the replacement tape sounds scary.

    Art Hackett - Ответить

    I wrapped two layers of vinyl electrical tape around the short side of an old gift card 3/8” from the edge. This “stop" prevented the card from going in too far. The card really helps to break the panel free.

    Paul Floro - Ответить

    This is a good tip!

    Lennart Saaf -

    Great idea! Wish I had read this before doing it. My less then optimal solution was to draw lines 3/8” around the cards, not as safe as your fix, but fast.

    Michael Piplani -

    Umm.. I’m not sure that I’d recommend using a repurposed credit card to open the display - I found that using the “pizza tool” to cut the old adhesive then using a pair of suction cups to gently pull the display up worked perfectly well.

    John Fisk - Ответить

    surely the card should have been designed such not to go further than certain distance with a barrier band.

    S Hussain - Ответить

    The cards don’t have any means to control the depth, its your skills which control it. Its no different from how you use a knife to cut your chicken up when you serve it for dinner.

    Dan -

    The pizza roller tool is enough to cut through the adhesive. You dont need to cut in a lot further. So the cards are really not necessary.

    sebastian.wittl - Ответить

    might be a stupid question but would credit cards or state ids work too?

    John Ta - Ответить

    You need the pizza cutter! The cards are used to hold the display off of the case frame.

    As for as using old credit cards and useless ID cards sure they will work. I wouldn’t use anything important ;-}

    Dan -

    No problems. I used two old credit cards and marked out a line using permanent marker so it was at the same depth as stipulated on this page. I even pushed it in a little deeper and no issues.

    • Gently twist the plastic card to open the space between the display and frame, and cut any remaining adhesive near the corner.

    • Using too much force will crack the glass. Work carefully, and don't try to create a gap any larger than about 1/4" (6 mm).

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

    • Only lift the display a few inches—it is still attached to the iMac by data and power cables.

    • With the cards inserted as shown near the corners, gently twist the cards 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 adhesive in the problem area.

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

    I would recommend using suction cups at this stage to lift the display.

    Go very slowly when lifting the display – give time for the adhesive at the bottom edge to stretch and flow. If you lift too fast, the glass can crack. That’s what happened for me.

    HABEEB102 - Ответить

    Did you use the pizza cutter tool first?

    Dan -

    WARNING!!! This is where you can crack you screen. TAKE YOUR TIME! Everything work fine for me because I took my time. I was very shocked at how fragile the screen is. It does have a small amount of flex but don’t push your luck. There were two things that made this easy for me #1 Once you have used the cutting wheel to your best judgement to cut the adhesive, start using the iFixIt plastic cards as spacers and space them evenly around the screen. I used 10 individual cards of and gently moved them up and down at each section two at a time. Once I started having less resistance, I combined 2(i.e. 5 sets total) cards evenly space to allow for move rigid and stronger movement to separate the screen. This really helped me to free up more adhesive. #2 before lifting the screen up fully, use tweezers to pull the adhesive like a string from around the entire monitor. This will make lifting the screen much easier since all adhesive will be removed. Finally when lifting the screen use the cards with your hands under them.

    Andrew Phillips - Ответить

    Would any of you consider the possibility of heating the glass with a hot-air fan before starting the process? In that way, the adhesive would let the screen go easier, I think.

    ManuG - Ответить

    The type of tape has a lot to do with it. If the original tapes are still present then the pizza tool slices through the thin foam core of the tape so heating is not needed. If on the other hand someone replaced the tapes with just regular double sided tapes then there is no foam core to split and there is a sizable risk the display will get damaged in the process of taking it off. So sure in this case a bit of heat might help, just be aware the LCD panel area is quite close to the edge along the top three sides so you also have the risk of dating it from over heating!

    • While holding the display up with one hand, use the other to unplug the display power cable.

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

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

    At this step, if you mess up anything with these 2 cables, especially when plugging them back in, even if you think you’re following the instructions here to a T, then you’re screwed.

    I would highly, highly, highly recommend AGAINST doing this at home.

    After finishing my hard drive replacement I reconnected these connectors to test my display before using new adhesive. Everything was working beautifully. But then when I applied the new adhesive and went to seal the display on for good - the display power cable somehow became disconnected! I had to reopen the Mac for a second time which was far more difficult with new adhesive. When reinstalling double and triple check that the cables are securely inserted before the final seal. Sounds obvious but it’s quite the annoyance if something goes wrong at this point.

    Interesting comments.. personally, I didn’t find the cables particularly difficult to detach and reattach. You do have to be patient and gentle. Personally, I found that a rolled up beach towel gently wedged between the unit and back of the display helped keep the glass up. Also, a small flashlight can be helpful to see the cables and connectors if you’re lighting isn’t perfect.

    John Fisk - Ответить

    I’d agree to John - not overly difficult. My workaround was to prep the screen for re-installation and then place it in front of the standing machine. The cables are long and flexible enough to be put in place even in this state. You can easily attach the cables and continue with fixing the screen to the housing.

    stefan - Ответить

    I would not recommend doing this step as pictured. The cable you are removing has little tabs on the wide side that can be depressed inwards towards the center of the connector, releasing the cable. If you just grab the cable as pictured and yank it out, without depressing the side tabs, you are likely to damage something. Don’t pull on the wires, use your fingernails at the connector to squeeze the very small little tabs inward to release the cable from the connector.

    The removal of the LCD power cable does require the left and right sides to be squeezed inwards towards each other first before removing, why this isn’t mentioned in the take apart can lead to damaging the iMac.

    I agree with maccentric. DO NOT just pull the power cable. Use your fingernail or spudger and gently press the tiny notch inward and towards you gently and one side will disengage. Do the same for the other side and it will slide right out. The notches just have enough edge to catch your nail or spudger. Using your nail is better as you can better feel when you have caught the edge and can feel the cable move.

    First: During reassembly, I highly recommend you connect these cables and do a test boot BEFORE you remove the protective tape on the adhesive strips. That way you can fix any issues(like a damaged cable) if something is not right and you have not re-glued the screen back down which will cause a problem. If you have a second person and everything is working after test boot, you can just leave the cables connected, lift the bottom of the screen and have 2nd person pull the protective tape on the adhesive strips and you can set the screen in place. Second I damaged the video data cable during reassembly on my late 2015 iMac- I did not get the connector straight and I damaged the wires on the cable. I recommend you have someone else hold the screen while you attach the cables - they are fragile. Luckily, the data cable was easily replaced for only about $20. If you must do this by yourself, just be careful I highly recommend have 2 people at this step during reassembly.

    At least on my “late 2013” model, the smaller display cable connector has tiny, tiny clips on the outside edges. These must be squeezed to unlatch it. Don't pull on the cable itself or the wires can be pulled out. Even with my small fingers, it was hard to grip the clips. When reconnecting, the connector will lightly snap into place.

    On the 2015 there are 2 cables.

    1. Once the display is loose use the Mac foam block sold from Ifixit to keep the display from rocking to hold open the glass

    2. Blow out dust with canned air

    3. Get a flash light and small flat edged screw driver

    4. Use the screw driver to slow pry loose the connector from the socket by gently inserting it in the gap on the left and then on the right slowly easing the connector from the socket towards the top of the glass

    5. The more center connector has a pull tape and a wire loop. Lift pull tape and the wire loop will raise up.

    6. Pull the wire loop towards the top of the glass to slide out the connector from its socket

    Have a late 2013 model and went to do the SSD upgrade. When going to remove the display we cracked the bottom left corner of the glass (just the glass frame part - not part of the screen that displays anything). We were also having difficulty putting re-attaching the display flex cable. Whenever we finally went to test it before re-sealing the screen back on with new adhesive it would sound like it is turning on as it makes boot-up noises and the fans start running, but the screen would just remain black. Just wondering if the crack in the bottom left-hand side of the glass/display would have damaged a part of the display assembly or if it would be more likely that we just damaged the display flex cable (which can be replaced for $26)?

    The panels are different since technology progresses at a rapid pace and Apple does like to be on bleeding edge of things.

Everything from 2012 late to 2015 should be the same though.

    That display cable connector is common to many Macs of the 2012 era. I’ve destroyed 2 in 38 years of servicing all types of computer equipment.

    As stated, there is a latch on this connector. If you put any incorrect force on the cable or connector during disassembly or reassembly, you will break the cable and possibly the connector. The cables can be purchased online and the video connector on the display is exactly the same.

    I repeat, if you pull out on the video cable after it has been unlatched instead of parallel to the logic board, YOU WILL BREAK IT.

    • 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.

    • Remove as much of the adhesive as possible by grabbing it at the outer edges, and then pulling or rolling it towards the middle.

There is a port for it on the replacement display.

    If you are just replacing the hard drive, I have found that it is quite possible to do while leaving the screen connected, making the process much easier. The amount you need to tilt the screen to access the little pull tabs at the bottom to release the screen is also sufficient to access the drive. I remove the drive while the iMac is upright. I also heat up the bottom of the screen to soften the glue and to help with the possibility of the glass cracking while doing this step.

    • Be very careful handling the display—it's big, heavy, and made of glass. The display has fragile edges. Avoid lifting the display by the corners.

    • Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface.

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

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

I do agree a suction cup can be helpful in the screen removal process. just to give you a better purchase, not pulling! As you can damage the screen if you pull too hard.

    • If you are replacing the display panel, you may need to transfer additional components from the old panel to the new one. Compare the back of the old display with the replacement display. Note all cables, sensors, and foam cushioning that are missing from the new display.

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

    • If the cable is glued to the chassis, use a heated iOpener or a hair dryer to soften the adhesive first. You can then slide an opening pick underneath the cable to loosen it. Never pull directly on the delicate connectors.

    • Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.

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

    Can I buy the kit without the SSD. I'm thinking of replacing my 3TB hard drive with a 4TB SSD.

    Also, would you happen to know what the maximum hard drive dimension that can fit inside of this iMac? I may try a 14TB hard drive instead.

    Larry - Ответить

    A 14Tb HDD does not represent any problem. But I will care about rising temperature. Must attach a heat sensor. If rise to high, it will suddenly shutdown to protect it.

    Is the thermal sensor needed? I fitted a replacement SSD and it’s all back together and the iMac’s fans are fine. They don’t go into full max speed mode.

    If you have a problem with the fans, you can always use Macs Fan Control (free) to set the speed. The sensor is not needed.

    • Peel the white liner off the back of the small temperature sensor board in order to expose the adhesive.

    • Adhere the temperature sensor board to an exposed, metal surface of the SSD, close to the SATA connector.

    • Fold the excess temperature sensor wires so that they are out of the way while you install the enclosure.

    Great pics ! Is that “temp sensor board” is already on my HDD IMAC ?? Or must I buy one ?

    Don’t bother with the thermal sensor. I didn’t fit one and the iMac is working fine and no fans are kicking in.

    James Clive - Ответить

    Instructions say to attach sensor to the SSD, but all pictures show it being attached to the SSD carrier. This may not represent accurate SSD temp as much of the carrier dissipates the heat absorbed from the SSD

    Confirmed, no need for the extra temp sensor on Mid-2015 iMac. (EMC 2806, Mid-2015 27" iMac). Just changed the old 1TB HDD to SSD, no extra fan RPM after power on.

    • The images used in this step come from a 2017 iMac. Your cables may look slightly different, but the procedure remains the same.

    • Slide the SSD enclosure into the space previously occupied by the hard drive.

    • Route the cables so that they will not interfere with any other components.

    • Try to keep the cables free from any sharp bends, and route them such that they are not pinched.

    The SATA cable on my Late 2012 was not long enough to comfortably attach to the end of the temperature sensor array after it was plugged into the new SSD. I had to fold the array and slide it under the SSD and housing. There was much resistance to the folding so I took it slowly to let the wires adjust gradually to the fold so they would not break.

    Unfortunately, the adapter that comes with it isn't long enough to avoid pushing against the screen in the front. One week after upgrading to SSD my screen fell off shattering and breaking the power connector on the systems board. A new screen is ordered but I'm hoping the power connector isn't damaged beyond repair. I'm going to try to adhere the HD adapter to the back inside of the case with 3m adhesive to avoid pressure against the screen.

    As a newbie, the only other upgrade I have done is to replace my iPhone 7 battery. I had trouble on reassembly.

    This is a great upgrade guide, but it would be important to me to see the reassembly instructions including the cautions.

    For example, I had issues with reattaching the plugs in the phone. I could see having an issue with them here, as well as repositioning the display back into the cabinet.

    Try 3m double sided tape from Amazon, it available in 3mm width which is ideal for iMac screen. It has a very thin foam and is much better quality than the cheap Chinese kits available on Amazon. You will have to trim it to size with a sharp craft blade as you fit. Don’t risk your screen falling off from using cheap tape in the so called fitting kits!

How are the temperature sensing and fan speeds affected by a swap? In the future if I install an SSD I wouldn't want the fans going full speed.

shaolindave - Ответить

The fans will go a little crazy because of the swap. At my work they swapped the HDD with an SSD and installed software to maintain that. You can download either, which I believe work just fine:

Do I need any special cable or adapter for replacement?

Joerg O Mir - Ответить

No special cable or adapter required. However, you do still encounter the constant high speed fan issue after replacement. My understanding is that they built the fan sensor into the firmware of the Apple issued hard drives, so third party drives result in a null value being reported and thus the crazy fan noise. I'm curious how others are solving that problem.

rickhendricks -

No I installed a WD 1TB SSD and fan speeds are normal. Just a way to get money needlessly

Frank Galphin -

Did some investigation into this. I found that OWC macsales.com has a complete wire harness kit that adds the plug-and-play cable with the In-line Digital Thermal Sensor to eliminate fan noise and maintains proper system fan control through the iMac's System Management Controller. No software hacks, or third party solutions needed.

Followed all the instructions. Had difficulty to connect the display data cable again. Very difficult! Clumsy connector, screen heavy and obstructing work, no good explanation nor detailed photo of connection. After finishing and restarting imac: nothing... after a while very loud fan noise. Had to bring it to repair store. Verdict: logic board damaged (burned) screen maybe damaged, and other minor things... cost: 1400€

Having just done this to my late 2013 27" iMac replacing my 3TB hard drive this is fairly easy especially using this guide, there is a bit of misleading information out there regarding the need for a thermal sensor cable. Well I can tell you my 27" iMac did need one, I had the sense to rebuild with out sticking the screen back on and try it without the lead so it was a quick job to fit the thermal sensor. I replaced the drive with a seagate Barracuda same as the original.

Peter Combes - Ответить

hey Peter,

I just did the same as you on a very same late 2013 27" iMac

I replaced the old HDD with a Seagate Barracuda (3TB newer generation) - but it looks like it doesn’t need the thermal sensor?

I booted on the new drive and the fans run on an average 1400, which is fairly normal I guess?

I also installed iStat and can clearly see that the HDD temperature is monitored! (30°C)

How did you notice that you actually needed a sensor? Did the fans just go mad?

Is there any other check I can do to see whether I need one or not too?

Thank you so much

Luca

This question about thermal sensors and Late 2013 27" iMac, need or not. There still seems to me at least uncertainty if it is needed. Especially when substituting a stock HDD for a new SSD. Would the authors and iFixit maybe add their position on this question?

Hi,

I have upgraded my 2017 iMac with a 500GB Crucial SSD.

The iMac is now painfully slow and struggles with the most simple tasks.

The Crucial SSD did NOT come with a thermal sensor and I did not install a third party one - could this be the root of the problem?

I’ve installed Mac Fan Control software which controls the fan speed no problem.

I’ve already replaced the screen as it broke during the upgrade and I’m reluctant to remove it again!

Any pointers greatly appreciated.

I’ve upgraded my imac 27 late 2013 (with 1tb hdd) with samsung evo 860 500gb. No need for thermal sensor! All working as it was before. So, maybe for some ssd’s thermal sensor is needed, but for this particular ssd - it is not.

hench1g - Ответить

Thank you for the guide. I found it generally spot on and was successful in swapping the HDD with a Samsung V-Nand SSD 860 EVO (2TB). I did use glass suction cups to get a good lift on the display which I think helped. With this upgrade I am betting another two years of service before I’ll feel compelled to buy another one.

I ran into fan issues after installing a 8TB hard disk (replacing a failed 3TB Seagate Barracuda). Tested the two fan control applications listed by shaolindave, but the free one (SSD Fan Control) has not been updated for a while and the other, HDD Fan Control, seemed overpriced… Did a bit of search and found this: Macs Fan Control. ( https://www.crystalidea.com/macs-fan-con... ) It is currently free, was recently updated and seems to be doing the trick…

My 11 year old and I followed this detailed guide and it worked like a charm. Two sets of eyes were helpful, but Jr. really did this almost entirely on his own. Once finished (just before re-sealing the iMac) we followed a youtube video to create a “bootable USB thumbdrive” to start-up the refreshed iMac. We then reinstalled the operating system (from the internet) onto the freshly installed hard drive. Very happy and proud. Very grateful for this well written guide.

Ben Lubick - Ответить

Actually you don’t necessarily have to take out the speaker and remove the cables connected to it.

It`s enough to take out the two scews on the top and move it carefully a bit to the side.

Then you can access the two screws holding the HD under it.

Don Lindo - Ответить

Hey do you need the sensor-enabled SATA cable or can you connect it straight into the mac?

Tom Halliday - Ответить

Hi Tom,

You can connect it straight to the iMac, but the fan may operate at full speed. You can get around that with software, i.e. Macs Fan Control.

Arthur Shi -

Great guide which allowed me to replace hard drive without using anything up, - yet.

Two issues for optimisation of the guide.

1) The front panel door for the HD adapter is taken off but not replaced in the guide. Leave it off or reattaching after SSD instal is not clear.

2) Second is the cable setup is cumbersome with the sensor adapter cable being too long and not optimised for the original setup.

Charles Michlin - Ответить

Hi Charles,

Thanks for the tip! I’ve added a step to replace the front plate.

Arthur Shi -

Nice! Did it under 45min. Another person helps a lot when you’re removing the cables. Skipped the part where speaker was disconnected, only loosened it and the hdd comes off easily!

Couldn't have done it without ifixit! Thumbs up!

Thank you so much in advance for answering.

Giuseppemaria Cavallo - Ответить

Hi,

I can confirm that replacing an Apple HD with a Seagate Barracuda (equivalent to the original) works fine, at least on my a iMac 27” late 2013 with Fusion Drive.

I know there’s mixed opinions about this, but in my case I didn’t need the OWC Temperature Adapter: I can see the temperature is monitored correctly and fans work as expected.

I just needed to open the iMac, replace the old Barracuda HDD, boot from USB, rebuild the Fusion Drive from Terminal, install Mojave and copy from backup.

Do not clone the HD if you have a Fusion Drive,: to create the new Fusion both SSD and HDD will be completely erased.

Apart from that, everything was pretty much streamline

Thank you so much for this guide: it would have been impossible otherwise!!!

Step 27 you do not need to remove the speaker. Loosen 2 torx 10 screws lift the front screw up a bit and shift speaker to right towards edge. You will see the 2 Hard drive screws. Much simpler.

Step 36 why are you using such a fancy box just to hold an SSD. Just pick up a 3.5 to 2.5 adapter frame for $4.99 at best buy. Waste of money that box.

In line temperature sensor about a 90% chance you wont need it . I installed a Western Digital 1 TB SSD in my 2013 27” without the sensor and the imac fans are running at normal speeds. Another possible money waster.

I am cheap as you might have guessed! Just trying to send some helpful info may save some money even,

Successfully followed the guide and no issues. It was one of the easiest repairs I’ve carried out. Much easier than the older 27” iMac. New SSD fitted and all working fine. Don’t bother wasting money on the thermal sensor as I didn’t fit one and the iMac is working fine with no fans going at it like a 747 taking off! Also I didn’t bother with the SSD caddy: just stick it down with some 3M sticky pads!! ?

My late 2013 iMac 27 has a 3TB Fusion Drive. When installing a new SSD to replace the mechanical drive, is the original SSD portion (in my case 128gb) no longer used? If used, does it still function as a single fused drive with the new SSD?
