Can't disable 'Local Guest' User.
Hi, I'm running 10.8 on a MacBook Pro Late 2011 model, and I took my MacBook in to get the display replaced. Ever since I got it back, a user 'Local Guest' seems to have been appeared. 'Guest' is shown as disabled in System Preferences, all checkboxes are unchecked. I just can't get rid of it. Thanks in advance!
MacBook Pro (13-inch Late 2011), OS X Mountain Lion (10.8.2)
