I have a Mac Mini. When I launch Terminal, the user name is not what I have in the Account (System Pref.) The prompt shows as "XXXXX ~Mac Mini:" Mac Mini is the name of the Admin User that I log into the system with... but not sure where that XXXXX comes from. (It's not XXXXX but actually a name of another computer that used to be in the home network before I bought this Mac Mini) When I try to change user in Terminal, by typing SU SUDO, it asks for password, but my admin password is not accepted. What's going on?
