Hi guys, I'm thinking of selling my 3 year old imac 27" and buying a mac air. Would I be able transfer all apps/music/photos via time machine onto the new Air?
Migration assistant to clone from your old Mac to your new one. Don't faff about using a time machine backup, just copy from one computer to the other. It's quick and it works incredibly well, I was surprised and very impressed when I did it from a Mac Mini to an iMac.
