Hi everyone, I am interested in upgrading my PowerBook G4 from 10.4.11 to Leopard. I have listed my specs below: Machine Name: PowerBook G4 15" Machine Model: PowerBook5,4 CPU Type: PowerPC G4 (1.1) Number Of CPUs: 1 CPU Speed: 1.5 GHz L2 Cache (per CPU): 512 KB Memory: 1 GB Bus Speed: 167 MHz Hard drive: 120 GB My questions are: Should I upgrade to Leopard? Will my machine be able to handle it? 1 GB RAM is the max it can take right now as my lower RAM slot won't recognize anything I put in there. If I do upgrade to Leopard, what's the best way to do it? I have read that a clean install is the way to go instead of Archive and Install. I keep a bootable backup of my current drive, so would I just be able to copy that information over if I do a clean install? Thanks for any help you can offer!
