I recently setup a brand new MacBook Pro M1 and the first thing I did was to update to the latest version of Big Sur. After the download completed, I was asked to enter my Admin password in order to restart the device. For some reason, entering the password seemed to do nothing so I just restarted the computer via the Apple menu. (I don’t quite get why it is asking you for a password to restart but I guess its a way of making sure the computer doesn’t restart when the user doesn’t want it to).
Anyway, once I restarted and wanted to enter my password on the login screen, it would not accept my password. I found some stories on the net about a bug in Big Sur that makes it forget which account is an admin account (or that account’s passord? Or both?). Anyway, since it was a brand new MacBook with nothing to loose, I reinstalled MacOS and, strangely, I did not even need to create a new user but the old password for the old user worked again.
So that was two or so weeks ago.
Today I wanted to update to MacOS 11.3 and it looks like the exact same thing is happening again. The update is downloaded and available to install but when I click on restart now, it asks me for my password and when I enter it the notification that “some updates could not be installed” pops up and that’s it. Here you go:
So I’m thinking: maybe I shouldn’t force a restart via the apple menu this time, because I have a sense for what’s going to happen then.
I can add that my password still works fine in other places (e.g. unlocking privacy features in system settings).
Any idea what to do instead?
