In another post.. had a question about updating .. currently have 10.2.8. And I found out that I need to purchase the software to update any farther.. but curious.. i have the disks that came with another iMac of mine.. a new G5 with 10.3.6. Is it possible to use those disks to update my G4? Bad Idea? No good? Just curious... thought crossed my still-learning brain.
