Hello Everyone, I just bought a new Macbook Pro, and I've started installing all my software and transferring all my files. I was wondering how the Snow Leopard Upgrade will work. There are two possibilities that I see: 1. I'll have to uninstall everything, create a backup, install Snow Leopard and then put everything back in again. 2. I won't need to backup anything, and Snow Leopard will install itself like an update. (Something on the lines of an iTunes update) Which one is correct? I don't want to move all my work to the new laptop and then remove everything after a couple of months.
