Unable to Log in to Guest user or restart Laptop
I noticed that Guest User is logged in on my Mac Book Pro, but I can't log in to Guest User as I don't know the password. Furthermore, when I try and restart my laptop I get the message:
"Restarting may cause other users logged into this computer to lose unsaved changes. To avoid losing unsaved changes, log out of all users before restarting. To continue without saving changes, enter an admin name and password and then click Restart"
This has never occurred before when I log out otu restart my laptop from my regular user profile.
However, when I enter my Admin Name & password it says the name is incorrect. But, the name and password are identical to those in User & Group Preferences. Therefore I am currently unable to log out or shutdown.
