Got an iBook G4 with the following spec: 1.07Ghz PowerPC G4 1.25GB DDR SDRAM 27.82GB HD (9.6GB free) OS X 10.3.9 Bought a Family Pack upgrade to Tiger, the Power Mac G5 upgraded with no issues: Insert disc, click icon, reboot & upgrade sailed by. Not with this iBook though: Insert disc, click icon, reboot, click through various dialogue boxes, installation media is checked, installation starts, about 30 seconds in: "There were errors installing the software. Please try installing again." So I tried installing again... four times again. Same thing each time. Is there an install log somewhere I can take a look at, cos I have no idea how to proceed? Or if you've any suggestions I'd like to hear 'em. Thanks for your replies.
