One of my friends has a Mac laptop. She can't remember the admin password and was asking if there was a way to retrieve it. I know on a linux box I could just do a 'linux single' at the LILO/Grub prompt (assuming it wasn't locked out). Is there anything similar she can do, or is a format/reinstall the only option? I wish I could help her, but I barely know how to turn a Mac on.

Thanks!
