So I'm getting ready to restore my MBP. Was wondering if I can just stick the Snow Leopard disc in to install OSX or do I have to install Leopard and then Snow Leopard? Also, believe it or not this will be my first time restoring from a backup. When I reformat the computer I can just plug my external in and pick and choose the things I want to put back on the computer right? Dont have to do a full backup?
