Happy New Year to all.... I need some help. Here is the setup: 2 iMacs, 1 MacBook Pro, several Expresses around the house for AirTunes, and 1 2TB WD drive attached to one of the iMac's via Firewire 800. I want to have a single source of music, movies, (everything for all iTunes on all Macs), on the WD external drive. I do not want to copy anything locally to any of the computers. I also do not want iTunes arranging any files, I have them structured the my PC world as well. Will anyone please give me a quick step by step on making sure I have this setup, and how to make sure new music is seen in all iTunes, (everytime I update a new album or folder, I keep getting duplicates and triplicates). Thanks to all... By the way, I have had these computers for about 2 months now, and am JUST NOW setting these up, ahh children!!!!
