I would like to share an iTunes library between my Mac Pro, which is in my studio and my MBP which is at home. Can I use one 1TB Hard Drive and move it between the machines, providing I keep all the iTunes library files on it as well as the media? If so does that mean that I can sync my iPhones & iPad to either machine providing it is connected to the library at the time? For historical reasons my iOS devices sync with my Studio Mac Pro. I don't like ripping DVDs on my MBP (in fact I can't because I have put in an optibay for an extra HDD) but use it to stream to my tv when home. At the moment I have to faff around with removable media to take it between locations. Any thoughts?
