How can I make all of my devices use the same iTunes library?
I have an iMac, Macbook Air, Macbook, iPad, iPhone and an iTouch. So, as you can imagine, I have many devices that need to be on the same page at all times. I take my Air to campus with me and use it for classes, along with my iPad, so I usually plug my iPad into my laptop for updates, dowloads, transfers, charging, etc... The same with my iPhone. However, when I get home and I plug my iPad or iPhone into my iMac, it does this whole (This iPad is currently synced to another library, would you like to Erase & Sync to this library). No. I want my Air and iMac to be the same so I can plug my devices up to either of them without having to worry about erasing or adding anything that I don't want erased or added.
How, if at all, can I accomplish this?
Thanks!
