Software Update not recognizing Admin Password
When I try to update my MacBook Air (M1 2020) from 11.2 to 11.3.1, I receive the following message in Software Update: "Software Update is trying to authenticate user. Enter password for the user "MyUserName" to allow this." I enter the correct password (which works in all other circumstances) and the window shakes as if it is invalid.
I have tried the following:
Restarting the Computer
Shut down, Close Lid, Wait 2 mins, Restart
Create new Admin Account
Change Admin Password
This is a computer that uses a network account to log in. However, we have also tried to use the local account that set up the network account, and it has also failed.
MacBook Air 13″, macOS 11.2
