Trying to update from Big Sur to Monterey .
Downloads ok, goes through the update process . After an hour it then opens the Home Screen and says do you what to upgrade to Monterey.
I can keep doing this all day, but doesn't change to the new system.
iMac 21.5″, macOS 10.15
Are you running any VPN, Anti-Virus, or Cleaning apps?
Try it in Safe Mode...
Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions.
Tried that, but just the same.
