Hello, So I have my main computer which is a MacBook Pro and I have a old MacBook Air with multiple hard drives attached for time machine etc. Is it possible (without signing up to Match) to auto sync the iTunes library's on both? This is because I have some devices such as my Airport Express's and Apple TV connected to my MacBook Pro but that means I always have to have it in the house and turned on. What I would like is if I rip a CD or download a song through youtube and add it to my library on my MacBook it auto syncs to my MacBook Air server? I would also like the ability to do the same the other way also, if I was to keep my Superdrive always plugged into my MacBook Air and rip a CD onto that library I would like it to also copy onto my MacBook Pro Library. Does that make sense? I would also like the album artwork to be copied etc also.
