I just purchased a G4 iBook with OS 10.4.11 that came from a high school. It won't allow me to upgrade the OS, see more info in "about this mac" or enter system preferences. It seems to be a scholastic version of the OS or maybe parental controls are simply enabled. A menu option available I've never seen before is "Student Logout". When I select this it requires a username and password. Neither the seller nor the school admin will give me any answers. When I Firewire it to my other mac with disk utility the HD doesn't show up. Any clue how can I wipe this HD and reinstall a fresh OS?
