Dear all, Before my rMBP, my old SR Macbook Pro died... the harddrive's stuff is mostly gone... I just received my iPhone 5. I also have a iPhone 4S where I want to transfer my music+playlist+other stuff in it. I did a search online and the answers always just tells you to copy the mobilesync data from the old computer over to the new one... This doesn't work for my case.. I was wondering how I can transfer my stuff, especially my music+playlist to my rMBP so I can have the music on my new computer, plus able to transfer it over to my new iPhone 5 without erasing all my stuff from my iPhone 4S? Appreciate your help!
