This is my first post in this year. Sometimes the Mac computers located in public places. And many people coming there and do their job. But some of them may access administrator password, create own accounts, drop large files on desktop etc. Sure, the computer owner don't like it and ask trusted person to change administrator password and temporary disable such account. You ca ask - Why not simple delete it? The answer - we may not sure is there important files on user desktop. The good strategy to wait a little and if nobody ask - delete it permanently. There is one trick how to do it.
Don't forget to click OK.
Sure, you must have administrator right to do that. Now Click OK, and Log Out. You see that `badguy' user disappeared. Now login again and see in System Accounts this banned user. To enable it just do right click and change the shell to user default. That's it.
As for Snow Leopard (10.6) we have to fire up the console and give such command to enable this user from there.
$ sudo dscl . -change /Users/badguy UserShell /usr/bin/false \ /bin/bashEnter your password and this user will appear in System Accounts again.
