I need help over here. My mom has a powerbook G4 17" that runs 10.2.8 and I want to upgrade it to 10.4. The problem is, the CD/DVD drive is broken ( Once you put in a CD, it ejects it after ). Will it work if I put in my Macbook's install CD in it? I kinda doubt that coz I know they re-wrote everything for the Intel Processor. I also have with me my dads 10.3.7 disc but it's only the first install disc. Will that still be sufficient? Thanks in advance!
