Turned off iMac during Sierra High installation update - wont load now
My friend accidentally turned off their iMac during the macOS Sierra High Update 10.13.3 and now the system won't load. It must of been during the system restarted and was installing Sierra High from the previous Sierra.
Is there any way to recover from this fault without losing any of the personal files on the hard drive?
Just wondering if a reinstall of Sierra won't wipe the personal data as trying to get it back to work and have never ever come across this problem.
Any suggestions much appreciated. Thxs
