I have a PowerBook G4 (12", 1 Ghz PowerPC G4, 1.25 GB DDR SDRAM) running OS X version 10.3.9. A friend had his PowerBook destroyed (it fell off of his deck into the swimming pool) and has since purchased a new MacBook Pro. He gave me his OS X 10.4.10 disk to update my PowerBook to Tiger. When I try to install it my PowerBook locks up and displays several lines of messages. One of them is "unable to find driver for this platform: PowerBook6,2" Does this mean these disks were made for my friends powerbook and will not run on any other mac? Is there anyway to get this to install on my PowerBook?
