Question: Multiple guest accounts reappear
After the upgrade to Mac OSX 10.13.1, and then rebooting, I get my disabled guest account to reappear on the login screen.
What's interesting is that there is TWO guest accounts appearing on the login screen. One of the guest account icon has bad graphic artifact.
I visited System Preferences, hit "Users & Groups", unlocked the padlock, then unchecked the box to 'Allow guest to log in to this computer'. Then rebooted.
After the reboot, I still find ONE guest account displayed. And repeated the same unchecking the box to 'Allow guest to log in to this computer.' Then rebooted.
The guest account APPEARED again on the login screen.
So, I went back into unlocked 'Users & Groups" in the System Preferences and did right-click over 'Guest Users' an 'Advanced Options' then changed the 'Login shell' to '/sbin/nologin'.
What is going on?
