High Sierra performs an EFI update to enable APFS My guess is I had a firmware password set and didn't disable it prior to installation, thus EFI update couldn't work. There was a problem that might have triggered this error. I ran into the same issue last night on my genuine MacBook 12" 2016. This shouldn't be too dangerous of a fix, but of course do have a backup first. If yours is not OK "diskutil repairdisk disk0" in Rescue Mode terminal (boot with CMD-R) fixes it. Started partition map verification on disk0Ĭhecking the EFI system partition's file systemĬhecking the EFI system partition's folder contentĬhecking all HFS data partition loader spacesĬhecking Core Storage Physical Volume partitionsįinished partition map verification on disk0 If you get this, then the partition is : diskutil verifydisk disk0 Like noted, I had this issue, and it was a problem with that little partition that's needed for firmware update.
It's going to check your disk, where the EFI partition lies.
If you've got a more complex machine, check the location of the EFI partition with "diskutil list" first. Should work with those Macs with just one SSD inside. Folks, you can try this even without rescue mode in terminal: "diskutil verifydisk disk0".
