How do I put all my music and pictures from my macbook air to an external hard drive ?
My macbook air is already full - I transfered everything from my desktop as soon as I got home with my new laptop. As it is already full, I would like to put all my pictures and all my music on a external hard drive. I am unsure how to do that. I've 'slide' the file to the external hard drive, but now, my computer is bizarre. If I'm in iphoto, I can see photos, but they then dissapear, etc. It's just bizarre and I feel this is not normal.
MacBook Air (11-INCH, MID 2011), iOS 5.1.1
