hi, i have 2 G4 desktop computers. The older runs on OS8.6 while the newer runs OSX. Im in the process of cleaning off the old G4 and wanting to install OSX on it - if possible. I tried putting the OSX CD into the old G4 but it rejects the disk everytime, giving me a message to reformat the CD or Eject. Is this not possible or is there a different way I can do this? Any help would be much appreciated. thanks!
