Hi There,
I have been experiencing same issue on multiple Macbooks in our company, where MacOS fails to accept the password to authorise System wide changes in System Preferences.
We didnot upgrade from catalina or any other version since our Macbooks came with Big Sur out of the Box.
The same Admin account works fine to login to Mac but when it comes to make any changes in System Preferences it wont let me(even to update the MacOS version to Monterey). when I enter the admin password it shakes the windows and does nothing. Please do note, wiping and or erasing is not an option at the moment.
I tried to search the issue on Google, and found some many other Mac users have this issue too and only few of them have this thing resolved by resetting their SMC, which is not possible because all we have in our school is M1 macbooks, which doesnot have any support to reset the SMC.
I would appreciate any quick support on this issue.
Thanks
