Hello, I will be getting snow leopard this friday and I wanted to know if I should do a clean install if it's possible. I know that I can upgrade straight from leo to snow leo, but I want to erase everything since my Leopard has started to act weird lately. I currently have Leopard installed, so should I: 1. Make a clean install of Leopard and then afterwards install Snow Leopard 2. Erase the partition and install Snow Leopard In case of #1 and #2, will i be missing iLife 09 which came already pre-installed on my iMac? How do i get it back? Thanks in advance.
