Can I upgrade my iBook G4 to run Leopard?
It's a fairly old machine that originally came loaded with Tiger. It has a G4 1GHZ processor and 512 MB of RAM. I have the Leopard OS discs that came with my iMac but they won't install on the iBook, presumably because the version of Leopard on the install discs is optimized for the Intel processor in the iMac?
