How do I fix the prohibited sign after logging in?
I have a MacBook Pro that will turn on and allow me to input my password at the log in screen, but after putting in the correct password, after a minute or so I get the prohibited sign. How do I fix this? I can not find the OS cd, and I opene it in safe mode and ran a dianostic of the hard drive and it tells me the mapping is okay.
