I am running 10.2.5 on an iMac 800, G4. I started with Jaguar 10.2 (CD version) and kept downloading the new versions as they came out. I have had it with 10.2.5. It sucks! I've had nothing but trouble with it and want to ditch it and go back to Jaguar. 10.2.4 gave me no trouble at all. How do I go back? Can I go back to 10.2.4 without the CD version of it? Do I have to go back to 10.2 since thats the only version I have a CD copy of? And if so, how do I do that? Thanks Jerry
