Pad below the iMac and prop it so it’s tilted back.Īfter that, the whole deal consists of delicately unplugging a few cables, undoing quite a few Torx screws (you’ll obviously need torx drivers), then removing the speakers, power supply (don’t touch the bare solder joints on the back), and logic board. You’ll find the NVMe SSD on the back of the latter, secured by one screw. It’s simple, but a few pain points:Ī post for the power supply is also a screw securing the motherboard. There’s a captive screw behind the motherboard that you access through a hole in said board. The webcam and primary display cables have flip-up locks, don’t just yank on them.īoth large cables connecting the power supply with the motherboard have latches. You must press these to enable removal and the large cable requires a fair amount of force. There are upward-facing screws behind the fan that are easy to forget. These are also slightly different from the others with a raised secondary flange beneath the actual screw head.Ī completely useless picture of what a late 2015 27-inch iMac looks like with the components removed. Just to prove I actually disassembled it, as well as ignored my own advice about a large workspace. And darn if Apple’s AIO’s don’t look better empty than others do assembled. Remember how I brought up the fit issue with the Sinetech adapter? I was able to screw the assembly in place by tilting the screw with its tip just in the hole, then pressing it towards the assembly.

This did unfortunately induce a bit of a bow in the SSD, but shouldn’t be a problem. If you’re brave, you can deepen the adapter’s and SSD’s indentations a bit with a round file and much care. Once you have the drive installed and are ready to test it, I recommend that you only do the bare minimum of reassembly (minimal screws, leave the display untaped, no speakers, etc.) so that you don’t have to repeat the entire disassembly again should the something be amiss with the drive or the procedure otherwise doesn’t work.

When the computer is operational again, boot with the USB disk you created, run the High Sierra Disk Utility to partition the drive and you should be on your way.
