Hello, I'm new to MAC, and i have a MBA 13'' i5 256GB. I also use Time Machine. I was thinking, if one day i decide to do a clean install, what is the best way? I have some things that i want to keep (Music, images, documents and some apps). If i restore using Time Machine i can't select what files that i want to recover, right? It is a good ideia to do 2 partitions in HDD? One for OSX and other for documentos, music, images?
