A PC IT guy here at work just called with a question about a friend's Mac. Apparently when the guy boots up he "is logging into firmware and then is prompted to type mac_boot." After typing that in he's fine. This IT guy just called me 'cause I'm the supposed Mac-guru at our company - this is a new one on me though - anyone know what's up? My guess is that it's a hardware issue - but what kind? Any suggestions?
