Apologies in advance for the stupid question. I have a 13" 2009 MacBook Pro, and I'm going to upgrade from Leopard to Snow Leopard this weekend. I was hoping to do a clean install and restore all my data from TimeMachine. So here is my question ... will TimeMachine backup and restore all my iTunes data (songs, apps, podcasts, etc) back to my MacBook after I do the clean install? Will my TimeMachine backup restore all files or does it leave out anything? Thanks in advance.
