Question: How do I remove user account with UID=0 (except of root)
While updating Parallels I got a :
ERROR: 15476. Cannot install Parallels Desktop because there is a non-root user account with the UID 0 in your system.
How do I change the 0 UID of Guest or delete it ? Another Guest user is Guest1 UID 201.
Guest1 nor Guest show on login screen.
