Hi guys, Just got my Snow Leopard disk... awesomely excited! Never done this before so need to ask... what's the best way of going about the upgrade? I currently have Leopard installed with Time Machine external HD running for backups. Should I stick the disk in and upgrade? then restore from Time Machine? Should I do a clean install, formatting first then installing, then restoring from Time Machine? Or what? I'd appreciate some direction. Just need to break the newb barrier Thank you!
