MY brother gave me his old powerbook G4 about 6 months ago, and a few weeks ago i turned it on and it tells me "some apps may not work correctly because date is before may 21st 2001 or something" the date was 12:00 december 31, 1969
so i called my brother and he said it was some sort of system crash, and to start saving files on isks and to reconfigure the computer somehow....does anyone know how to do this? Do I reinstall OSX or what? Please help
thankyou
