Introduction

Use this guide to replace the HD SATA cable or to add it if your system was originally configured with a Blade SSD only so you can add a second drive.

  1. 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.
    • 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 - Réponse

    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 - Réponse

    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!.

    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

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

    • Continue wheeling the tool up around the top left corner.

    Ajouter un commentaire

    • 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.

    Anthony Zimmerman - Réponse

    • 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.

    • Push the tool around the top right corner of the display.

    • Wheel the tool down along the right side of the display.

    Ajouter un commentaire

    • 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.

    Ajouter un commentaire

    • 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 - Réponse

    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 - Réponse

    • 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.

    Anthony Zimmerman - Réponse

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

    • Slide the card toward the center of the display, to cut any remaining adhesive.

    was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

    Julia S. - Réponse

    • Put the card into the corner again and let it stay there to keep the adhesive from resettling.

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

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

    • Slide the plastic card toward the center, again stopping just before the iSight camera.

    Ajouter un commentaire

    • Insert the card back into the top left corner.

    • 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.

    Marco De Palma - Réponse

    • 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!

    The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

    • Flip up the metal retaining bracket on the display data cable.

    • Disconnect the display data cable.

      • This is a delicate connection that can easily be broken. Be sure to pull the display data cable connector straight out of its socket, toward the top of the iMac.

    I replaced HDD to SSD and assembled parts again. When I boot up the iMac, I found black lines on display (looks partly not broken).

    I searched Internet, and some says graphic card problem, but I didn't touch anything but cable to lift up.

    Could the damaged display data cable cause this situation? I hope I could fix this by just replacing the cables..

    • 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.

    Thank you Stef, that's what i will do next time, i cracked the lower part of the screen went opening very slowly, that's probably why those "tabs are for !!

    Peter Haigh - Réponse

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    Todd Derek - Réponse

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

    Andrew Stephens - Réponse

    • If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.

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

    Would have been helpful to box the same red area when using the plastic card to separate the glue. Since the red blocked picture is inverted, if someone doesn't pay close attention it may not be obvious that the area of concern is at the right top of the graphic pictures in which the plastic card use is being demonstrated..

    • 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.

    • 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.

    hey Simon, I used 2-sided tape….this is assuming the new sensor doesn’t already come with an adhesive surface already applied.

    a roll of kapton tape for your own peace of mind will make sure nothing detaches from thermally-induced adhesive crystallization

    make sure you position it in such a way that you can easily plug the lead back into the mobo….not a lot of length to that wire

    • Grab the hard drive and left hard drive bracket together.

    • Tilt the left side up away from the rear case, and slide the assembly to the left.

    • Remove the hard drive and left hard drive bracket from the iMac.

    Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

    If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

    Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

    Regarding the screws on the power supply board (step 35), I can confirm these are not T10 screws as shown in the guide. In my Late 2015 Retina 5k model, the screws are T8. Morgan mentioned T9 and depending on your T9 driver, it may just barely fit but can easily slip and strip the screw. A T8 driver goes deeper in and holds the screw properly.

    This connector was very difficult for me to remove (even after pushing the disconnect tab). Eventually I had to use a pair of needle nose pliers to wiggle it back and forth out of the socket. A lot of the cables on the my late 2015 model were very tight and a struggle to get out.

    • 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, like opening a mailbox, to reveal the AC inlet cable connector.

    • Disconnect the AC inlet cable connector.

    To reassemble, do the same in reverse but keep power supply board more upright than slanted down when re-inserting it in to the lower right corner. The lower right screw post has an protrusion under/behind it and the Power Supply's small 2 wire plug must fit between the front of your Mac and the obstruction. Then it just slides right in and then screw it down.

    Use a piece of tape around the antenna cables to keep them in the same order, makes reassembly a little easier.

    • Use the flat end of a spudger to disconnect each of the four antenna connectors from the AirPort/Bluetooth card.

    • Note the original positions for each connector when reconnecting the cables. From left to right on the card, the antennas are connected in the following order:

      • Leftmost

      • Top

      • Upper right

      • Lower right

    My iMac has a slightly different assembly. There are 2 - T5 torx screws holding little clamps for each cable (2 clamps per screw). Certainly more secure but another size screw to deal with…

    • This is a delicate connection that can be easily broken.

    • Flip up the metal retaining bracket on the iSight camera cable.

    • Pull the camera cable connector straight out of its socket, toward the top of the iMac.

    During disassembly, I taped the cable up and out of the way, as it tends to get in front of things.

    • Use the flat end of a spudger to disconnect the headphone jack cable connector from its socket on the logic board.

    • Gently push the cable out of the way.

    • Remove the following screws from the front of the logic board:

      • Two 23.7 mm T10 screws

      • Four 7.4 mm T10 screws

      • One 20.8 mm T25 spacer screw

      • One captive T10 screw

        • This screw is beneath a hole in the logic board. You'll need a fixed screwdriver or the 60 mm extension from an iFixit driver kit to reach it.

    The central screw is very difficult to reach! Use a long and very thin T10 screw driver

    MrSchaeffer - Réponse

    On my late 2015 there is another T10 (approx 16 mm long) on the lower edge slightly left of the hole in the logic board giving a total of 4 screws along the bottom edge.

    I’ve also found an extra T10 in my late 2015 iMac

    • The hard drive SATA cable can't be removed just yet, but will get in the way of removing the logic board.

    • Pull the cable and connector through the right hard drive bracket. Move the cable to the right side of the iMac, out of the way of the exhaust port.

    Anyone know if models that shipped with only a bladed SSD have the SATA cable still inside? I’m guessing probably not, but haven’t been able to confirm anywhere.

    • Tilt the logic board slightly forward.

    • Lift the logic board straight up and out of the iMac. Be careful not to snag on any of the screw posts attached to the inside of the rear case.

    • When reassembling your iMac, be very careful to align the exterior I/O ports correctly. The logic board can sit crooked even when secured with all its screws.

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

    To help me line up the IO ports, I filled all the USB ports on the back with thumb drives before I screwed the Logic board back down. Worked like a charm!

    • Pull up on the SATA power cable connector to disconnect it.

    • Unplug the SATA data cable connector by lifting it up.

    • Remove the SATA cable from the logic board assembly to get it out of the way and prevent it from being damaged.

    Where is this cable sold

    mert - Réponse

    Is this picture correct with 7 pins? Or is it form the 5k version? (See comments on that case below).

    There is an cable on eBay with 5 pins.

    Steve Nilsen - Réponse

    This guide was written the year before the 5K model first came out. The cable in the photo is definitely for the model listed, although it’s always possible Apple made more than one variation.

Hi,

If I buy a model with only ssd drive and I add a hard disk,is the sata cable present inside the iMac?

Thank you

Antonio - Réponse

I have the same question.

glennfeldt -

I took the plunge and bought a Samsung 850 EVO 500GB SSD to get some more storage space in my iMac. (when I bought the iMac I configured it with a 250gb SSD only) After some research I figured out that I had to buy a SATA cable as there is none pre-installed cable with my configuration. Nor does it come with a HDD cradle/bracket, but I solved that with two strips of super sticky double sided tape to mount the drive.

When booted up and logged in a message popped up telling me that it had found the new SSD drive and wanted to format it. So I formatted it and it works great.

Oh, and if you have one of those very thin plastic "credit card/business card" you will be just fine using that to separate the display from the body. No need for a guitar plectrum or the "pizza cutter" shown in this tutorial.

glennfeldt -

No. At least, not on a Late 2013 iMac 27".

Hello,

anybody knows, where should I buy this SATA cable, since I also would like to take one more SSD to my iMac.

I have got a Late 2013 iMac 27 with SSD from factory.
