Okay guys, I have a Mac Pro and a Macbook Pro. Both run on Maverick OS. The laptop is my DJ-ing laptop, so I tend to keep that iTunes library updated the most. A year ago I copied my complete music library from my desktop to my laptop in order to have both of the computers current on my music. I'm looking at the iTunes library on my desktop and laptop. The desktop has 7390 songs. The laptop has 6068 songs. Is there anyway to find out which songs were not transferred to the laptop? I can't think of any easy way to do this.
