Hello guys! My 2017 13” MacBook Air starting show a blinking file in the screen and didn’t turn it on. So, I took to the Genius Bar, where they said the problem was with the drive. So, I bought a brand new drive: OWC 240GB Aura Pro X2 SSD and changed it on my own. Followed the instructions from the website (I removed the battery first and then change the drive). However: • The drive is not visible in the menu in Disc Utility from Recovery menu (after holding OPTION + COMMAND +R + STARTUP ) • Checked the ‘show all devices’ still not able to detected • My macOS is Sierra 10.12.6 Please could anyone help me with that? Any ideas what does it could be? Thanks in advance!
You’ll need to setup an external drive first as your boot drive. You are facing a macOS issue. OWC SSD requires High Sierra be installed on the system first. The reason is the systems firmware is updated during the OS update. But as you know you have a small problem ;-} Your current drive is dead! And it was running Sierra not High Sierra. So… We need to first plug in a drive externally to act as a surrogate internal drive so you can install High Sierra onto the system and magically update the systems firmware! Once that’s done you can then install the new OWC SSD into your system. Hopefully you have an external drive which we can use to setup. Make sure you don’t have anything on it you care about. Once you do Restart your system using the Command (⌘) & R keys to enter into macOS recovery.
