So a couple of weeks ago I purchased my copy of Snow leopard and I was wondering if there are any tips or things I should follow to have a quick and safe upgrade. Once I can get my hands on an external hard drive I want to back up all my files on to it and then erase my mac and put it back to factory settings like when I got it with the Leopard disc. Then after giving it a quick set-up "fresh and new," install Snow leopard. Does that sound good? Not a major thread just wondering.
