I currently, and since 2007, have always sync'd and backed up to my iMac 27" desktop, and of course that resides at my home. I also have a MacBook Air that I use much more frequently these days, and I usually always have it with me. My 6S Plus will be delivered to my work office tomorrow. Can I sync my current 6 Plus to my Macbook Air so that when my new 6S Plus arrives tomorrow I don't have to wait until I get home to activate it? I would love to be able to sync my 6 Plus to my Air so that I can activate the new 6S Plus immediately. I've previously thought that it was not possible, but you guys are smart--is there a way?
