I need help. I have fallen heir to an old iBolok G4 running Mac osX Ver 10.4.11, 1.2 GH, 512 MB 5DRam. Don't know what all that means of course. Anyway, I'd like to sweep it all, and upgrade this little notebook, so I need install disks I guess and I just don't know what else. Can someone give me some direction?
