My iMac (2019) downloaded Ventura but in the last stage of black screen and encryption bar it got stuck with less than a minute to go
Am afraid to turn off and turn on.
iMac 21.5″ 4K
How long has it been in this state ?
Minutes, Hours ?
Depending on various factors like would version of macOS was previously installed ?
An iMac from 2019 may have come originally installed with macOS 10.15 Catalina and upGrading to Ventura may require patience
Patience as in Ventura needs to finish installing
If the delay has been more than 1 hour.
Force Shutdown the computer by holding the Power Button until it turns Off
Pause 30 seconds
Unplug ALL External Drives ( Optional "
Restart the Computer in Safe Mode.
This may or may not allow the Installation to complete, hopefully successfully
