New MacBook Pro 13” w/M1 SOC - turned on and Migrated data from old iMac (OK)
Used old Admin OK - was data missing from Admin user so
Tried Migration again on the Admin user only and Big Sur backed up Admin User
then Migration started but did not complete, possibly because Admin was
now not available, canceled, then Big Sur no longer will allow startup because Admin user
is unavailable.
How to get and reload, or fix, Big Sur O/S?
MacBook Pro 13″, macOS 11.0
This has been resolved
How was this resolved? I have the same problem, after Migration Assistant caused all apps to not being able to do File > Open (no dialog box appears). Apple Care instructed me to go into Recovery, erase my drive and reinstall Big Sur. Problem is, Big Sur says there's no authorized users, so it won't continue. Now I'm forced to go to Apple for them to install a fresh MacOS, after waiting days for my appointment.
Thanks so much. This resolved my problem too, after doing it a 2nd time. The first time the install didn't see my Untitled drive.
I searched for days, looking for this solution. Now I know to search Apple Support.
