Yesterday I restarted my MacBook Pro and it started installing updates after I logged in again. The problem is it does not complete. It fills up to 100 %, then hangs for like 10 minutes and ultimately shuts down. When I power on the MacBook Pro again the same happens cycle is about to take place.
I tried to reset the NVRAM and also to check the disk using CommandOptionPR. It seems I have DataVault enabled and I am also unable to unlock the drive. When I try to reinstall OS X/macOS – where I have already accepted data loss – I can not complete the task because of the locked drive. When I unlock the drive using my correct password, the main drive disappears.
I have tried to fire up the MacBook Pro in safe mode and also logged in as a guest user. The laptop just can not complete the login process for my user.
What can I do to resolve
