Hello experts! I have an old G5 2,0Ghz (I think it's the Q37) and it runs with Tiger. I have to run an old scanner software that only works with Jaguar. I bought a Jaguar-Version on the bay and it does the restart, but cannot boot from the CD and therefore cannot start the installation process, either. The seller didn't mentioned anything, but I noticed that the back of the CD-shell says "2Z603-7378-A Mac mini Media Multilingual". Does that mean it isn't the full version but just a recovery disc for a mac mini? Is that the reason it doesn't work? Any other way to get the full version of Jaguar? Thank you very much in advance!
