Okay, here's my issue, I just got a new Mac Pro and I have copied my iTunes library to the new MP from my older Macbook Pro. I want to find an easy way to sync any purchases / additions to the new one when I get home without manually copying and pasting to the MP from the MBP. Also, I have a pretty long list of rules on some smart playlists to filter songs I don't want in it. Mainly by way of checked status in iTunes. This makes it easier to shorten playlists that I then sync to my iTouch. My question for this second topic; can I also sync the checked status of my entire library without copying and pasting from one machine to another? Thanks for any thoughts!
