I have an iTunes playlist on the old iMac. I was going to use Migration Assistant, but I'm afraid it might remove the files from the old computer because that's also the family computer and my sister's iPod is synced to that computer. I only want to move over the one playlist. Can I do that and will it completely remove those files off the old computer? Also, how do I sync my iPhone with my new MacBook, it's synced to the old iMac.
