Mac Laptop SSD ReplacementGuide ID: 125961 - Draft: 2019-11-05INTRODUCTIONRecently I purchased a OWC Aura Pro X2 SSD / 480 GB1 x 229.99 through iFixit.com. I havenoticed that while attending college my storage space has evaporated due to curriculum requiredinstalled programs. I will be creating a clone of the current hard drive onto the new hard drive beforethe install. Be sure to follow each step according to the outline in this tutorial to ensure success.This will save you tons of time and hassle.I had a clean install of OS High Sierra on a separate external drive. This helped me when I rebooted,as the new SSD was not found and could not be formatted or improved upon. Using the external Iwas able to get the drive recognized (due to a necessary Firmware update within High Sierra) andfrom there was able to install the new OS onto the new drive. Read that again, it might be helpful toyou.TOOLS:PARTS:Western Digital 2 TB Elements External HardDrive - USB 3.0 (1)OWC Aura Pro X2 SSD (1)Pro Tech Toolkit (1)This document was generated on 2019-11-06 08:13:07 AM (MST). iFixit — CC BY-NC-SAwww.iFixit.comPage 2 of 13

Mac Laptop SSD ReplacementGuide ID: 125961 - Draft: 2019-11-05Step 6 Shut computer down and flip over to remove back. Use the P5 star tip to remove screws. Placethem in a safe, none slip container. These screws are really tiny. Also, the screws closest to themonitor are the shortest and must be separated to ensure they go back in same slot. Otherwiseyou will have screws stick out in these slots.Step 7 A Torx T4 bit is needed to remove the screw holding the current SSD card in. Only pry the SSD upthis much to remove it. It will be harder to put the new one in vs taking the old one out. Don't worry,it is the right part. Also, be sure to fully seat the new SSD. Failure to do so will cause the drive notto show up in the next step. See pic.This document was generated on 2019-11-06 08:13:07 AM (MST). iFixit — CC BY-NC-SAwww.iFixit.comPage 6 of 13
