I bought a computer from someone and it has foolproof installed. The seller do not know the password. I cant even make it boot from the floppy. I look other information which suggests using AppleScript. But applescript is disable. Some suggest boot from a floppy, but it won't let me boot from floppy. I only get to the happy mac, and then it reset itself. The shift key to turn off extensions can not turn off foolproof.
