After all, the adhesive strips can also be used only once!įor those replacing the hard-disk with an SSD: I highly recommend the Angelbird model 'SSD wrk for Mac' (. 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. During the operation itself, I had the guide open before my eyes on my iPad and followed it step by step. I recommend reading at least twice the whole procedure *before* beginning. The repair went smoothly: to anyone trying this, please carefully follow the iFixit step-by-step guide.

So I ordered the RAM chips from Kingston and a 256 GB SSD from Angelbird. It was a good opportunity to increase the RAM from 8 to 16 GB. I had to replace the HD as it failed after less than two years. This is much easier than removing the power supply and logic board and all of the associated connectors and screws. 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. I installed 2 8GB modules (1600MHz DDR3L SO-DIMM PC12800 204 Pin) without much trouble. 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. 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. DISASTER! The screen cracked! I used the tool slowly and carefully and despite this, the screen cracked. I used the iMac Opening Tool just as shown in this guide to separate the tape.
