Hey, everyone. This has been a huge pain in the ass for me and I need some help! My friend has an old powerbook g4 6,2 with a clean install of 10.2.7. I'm trying to install 10.3 from the black install cds (there's three of them) and the computer is just spitting them out no matter what I do. My Macbook can read the install cds just fine so the cds are not damaged. As for the powerbook, the computer can read the grey cds perfectly. That's how the clean install was done. I have tried holding "c" when it boots, holding "alt/option" when it boots. It just spits out the disk. I don't have a mac that can run 10.3 to do the target disk mode install unfortunately. Any help would be awesome!
