Hi all, I will be getting a MBA soon and wanted to know how to prepare for it. I also got a 3tb Seagate external HDD from costco. I currently use an old 2006 white macbook so I have no idea how to setup automatic time machine backups. I want to use that HDD for itunes and photo librarry along with backup and want to know how to do it. Also, what apps should I delete to have more space? and is there an guide as to hwo to do it.
