User not visible on Users & Groups
I have a very odd issue. I use Mac OS Mojave and have two users set up. My user (admin) and a standard user.
The other user is not shown, when I go to "Preferences" - "Users & Groups" But the user can log on and is also visible on the logon screen.
Very odd is also that the users home folder is located /Local/Username where my user is at /Users/Username
For now, it works and there is no real issue besides that I can't administrator the account, BUT I tried to update now to Big Sur and then I was not able to log in to the account. I always got the wrong password, but I know it is correct. And because I can't administrator the account I can't change the password, even with the terminal it did not work. So I restored the Mac to a previous state. Tried it again with the same result.
How can I fix the user account without setting up everything from scratch?
Thanks for the help.
