IMPORTANT: macOS 10.13 High Sierra (or later OS) must be installed on the host computer BEFORE installing this SSD for the first time. You will need your original Apple SSD in order to do this. These OS versions include an EFI firmware update for your Mac. Without the update, the computer will not recognise the SSD. This process is separate from and should precede the other processes described here. Note that when installing the OS onto the drive itself, macOS 10.13 or later is also required.

SSD INSTALLATION: 

- You can find plenty of IMAC SSD installation videos if you do a search on youtube.

OS INSTALLATION:

- Power on the Mac then immediately press and hold Cmd-Opt-R keys. If you see a Wi-Fi menu, choose your preferred network to continue; you may need to provide network credentials.
