I got that for the GM candidate. The problem turned out to be a corrupted EFI partition. It's an MS-DOS formatted little slice that's needed when updating the computer firmware.

If the update fails, the installer won't proceed. I booted inoto rescue mode, checked the partitions with 'diskutil list' and 'verifydisk' (terminal), and fixed the EFI partition. 'diskutil repairdisk '. You can find more details of the error in the ia.log file, in the installation directory.

Look for lines related to firmware, it might refer to inability to mount the MS-DOS EFI partition. That's what I had.

But I don't have the logs anymore. Folks, you can try this even without rescue mode in terminal: 'diskutil verifydisk disk0'. Should work with those Macs with just one SSD inside. If you've got a more complex machine, check the location of the EFI partition with 'diskutil list' first. Could be disk1 as well.

It's going to check your disk, where the EFI partition lies. Takes a few seconds. Like noted, I had this issue, and it was a problem with that little partition that's needed for firmware update.

Macbook 12' 2017. Click to expand.I 'fixed' it somehow and got High Sierra working last night.

• went to disk utility and ran first aid, got a message saying there was an error. • rebooted into recovery mode and ran first aid in disk utility.

• the same error message did not pop-up • ok??? • rebooted back into regular mode and ran first aid again. • no errors this time • reopened HS installer and after 30 minutes it was done and working. I don't know what I did but it seems to have worked, maybe the first aid in recovery mode just fixed it without telling me.

Hi there, what worked for me was to restart in Safe Mode (Hold Shift while restarting) and then run the app upgrade. The OS was somewhat slow in Safe Boot but the upgrade went smooth (approx 40min) from the app store. Also AFPS file system was installed on the system disk, whereas Bootcamp partition (NTFS) on the same disk was kept intact as well as ExFAT file system on my other SSD. Works fine so far (48hrs of testing), earlier installation of Windows10 is booting also flawlessly from Bootcamp. MBP 15' mid-2010 Samsung SSD and Optibay (Kingston SSD) hope it helped. Solved Had the same issue.
