I recently bought a 12" G4 powerbook with OSX 10.3 loaded from two disks supplied with the powerbook: "software install and restore 1 of 2" and "software install and restore 2 of 2". I'd like to load OSX 10.3 on to my G4 dual powermac tower (currently running on OSX 10.2.8). Is this advisable? I've heard rumours that there may be compatibility issues. Please can someone tell me if it is safe to load up these disks.
