I moved my playlists from my pc to my macbook by replacing both library.itl and library music .xml files in the itunes folder on the mac with the 2 files from itunes folder on my pc, itunes on the mac immediately showed the playlists. I tried going to Preferences->Advanced->Change then navigate to where I saved the actual mp3's and select the main folder but when I click on any song in the itunes library, it is asking me to locate the tune, help?
