... and need HELP! Can't work out how to replicate / change some of my processes. Assuming that the 2-3 macbooks will be mobile and not stationary, I need some advice on how to do the following: 1. Music / TV / movie purchases, ripped DVDs, are all stored on the iMac so that I can sync with the iPhone / iPad and for streaming to an Apple TV. If I don't have a dedicated Mac, how can I share the content amongst my devices and ensure the Apple TVs can stream (has to work for music, TV and movies)? 2. Time Machine backs up everything on the iMac. My biggest concern is photos. I have a lot of them and want to make sure they get backed up. How can I back up the Macbook (that has my photos) without constantly having to connect an external drive? Does Time Machine work over WiFi to an Airport Extreme? Any suggestions for how I can get a similar setup but without a stationary PC? Cheers.
