I am installing Snow Leopard on My Tiger computer. Backed up the files 1. I was wondering since I am on Tiger will I need to do a clean install or just an upgrade? (Dumb question but I need answers) I have the upgrade disk and I heard the upgrade disk is the exact same as the box set and I do not need iwork 09 cause I already have it and I don't need ilife 09 because I have final Cut pro, photoshop, and I have some HTML knowledge. Also, i have no interest in music making so I don't need ilife. 2. If I do need to do a clean install how do I do that? 3. Could I just do a upgrade?
