Can't change my account on App Store login prompt
There - I have a friend who has an M1 MacBook Pro previously owned by her parents. On opening App Store, a login prompt popped up. However the username (which is her parent's) couldn't be edited.
(Note though, in the System Preferences, the device has been re-logged in with the friend's own Apple ID)
I tried my device (MacBook Pro 15" 2017) but I didn't have this problem. Seems like some funny viruses or bugs stuck in my friend's device...
Anyway, could anyone please tell me what's wrong?
