hi all, those that use their MacBooks as a companion computer to their desktop, let me know some tips on how you keep things in sync. I have the new iMac retina (1TB fusion drive), macbook retina (256GB), and old MBP (256GB). I will use the iMac mainly for browsing, word-processing, lightroom, and photoshop. I use the macbook on the go at work. My wife uses the MBP as her main computer. I want to try to centralize things like music and photos, either on the iMac or possibly even a NAS. What do you guys do? Thanks!
