I'm not sure if there has been a thread on this [i did a search and found nothing], but i need to know how to create multi-libraries in iTunes within a user account. Is this supported? I googled and found out that Windows iTunes supports this by pressing Shift while double-clicking the iTunes icon. It will then prompt for which library to use. I'm at work now and i haven't tried it on my Mac. I don't have iTunes on my Windows laptop to verify this. Is this true? How is it done on a Mac? Thanks!
