I got a Macbook Pro to replace my Windows laptop and want to sync my iPhone to it. Most of you will know that when you try to do this, the new machine will say that it needs to format your iPhone before it will sync. I copied the iTunes folder from my Music directory on my PC to an external HD. I didn't keep music in iTunes on my Windows machine, I kept it all separate. I have already imported all of my music into iTunes on the MBP though. What do I need to do to sync my iPhone to my MBP without having to format it?
