Hi, My roommate has an ancient PowerMac G4 / 450 Mhz that runs on 10.3.9. Recently, he installed an Airport update that came up in Software update. When trying to restart, the computer wouldn't boot anymore but got stuck on the grey screen w/ grey apple logo, without any error message. Does anyone have this problem, too? If yes, are there any easy workarounds? As of now, I am planning to boot from my 10.3 Install disk and try to restore the system, hopefully without losing any of his data. If you have any suggestions / comments, I'd be very grateful.
