Locked out of my own iMac
I loaned one of my imacs to a friend you who changed the admin and primary user passwords. She has now left the city and cannot be found. I now have a computer that i can get into as a guest but cannot do much like upgrade or update and so on. It never came with install discs... Have can i change the setting to regain control of my computer? Anyone? Bueller?
iMac, Mac OS X (10.6.8)
