In contrast to my MacBook Pro, the update finished without problems on the iMac.

Incidentally, I also have a late 2009 iMac where the original hard drive has been swapped out (drive failure - not even the same manufacturer) and an SSD occupies the optical drive bay. Afterward, I put the SSD back in and installed Hugh Sierra without any problems - as the firmware update had already been completed, there no longer seemed to be the system check that had tripped me up previously. The installation with the original HDD completed without any problems, including the firmware update. Luckily I kept the original hard drive around, and after trying the newest installer and rebooting into safe mode several times without any joy, I just took a screwdriver and put the old HDD back in temporarily (there are good guides on ). Turns out it was the aftermarket SSD I had installed pretty much as soon as I bought it.

The easy fix is to verify your backup and then erase the volume and run the installer against a blank / erased main storage drive.īecause the APFS requires support from a new version firmware, your mac's firmware will have to be updated to the latest version during the installation of High Sierra.Īfter the first restart, the installer prepares the latest version firmware which suitable for your mac model onto EFI system partition of your main disk with bless command.
