Update procedure to Monterey 12.5.1 does not accept user password
I am trying to update Monterey 12.5 to 12.5.1. Clicking on System Preferences>Software Update>Restart Now, brings up a small window (see attached picture) that asks for my user password. I enter the password for my user and press enter, then the window shakes and nothing else happens. This window remains.
I've tried restarting the Mac, but the same thing happens. Is there a way to correct this problem?
Thanks.
