I've been using a G4 PowerBook until recently when I got a new iMac. The PowerBook is a G4 and the software is version 10.4.11 and the iMacs software is 10.5.4. My question is could I use the install discs the iMac came with and put it on my PowerBook? And if so, is it gonna be a hassle to do? tl;dr: Is my PowerBook old and busted, or does it still have enough in it to run newer software? I know it sounds like a dumb question, but any help would be greatly appreciated here.
