First and foremost thanks in advance for all replies! I just purchased my first MAC,Powerbook G4 (12inch), from a friend and am trying to load my personal information on as the owner. Previos owner erased all of his docs and personal information but for some reason when I change my name as Admin the "Short Name" field remains the same, with his account name? How can I change this? In addition is there anyway to "format" all of his "hidden: files but still keep the applications whole the and music in iTunes that got granfathered in the purchase of the G4? Any link to a "clean up" of a used MAC would begreatly appreciated. Once again thanks to everyone for their help.
