Hi there, I recently acquired a PPC G5 to run Pro Tools 7.3 on, but the G5 had OSX10.5.8 installed which is incompatible with that version of Pro Tools. It had previously had 10.4 installed and came with the according DVD but I have been utterly unable to install this OS. Whenever I try to boot from the disk I end up at a kernal panic text screen and have to power down when the fan goes crazy. I connected my G4 ibook to run the G5 in target disk, wiped the drive and installed 10.4. The installation and registration completed and runs fine as the boot drive for the ibook but then whenever I power the G5 up to boot from it's newly wiped and OSX installed internal drive it goes straight back to the kernal panic screen. . . Please help, I've been driving myself nuts with this for 2 weeks now! Many thanks.
