Currently have iPhone 4S (7.1.2) and 2012 Mac Mini (Mountain Lion). Any tips or suggestions on whether I should update the Mini to Yosemite before receiving the iPhone 6 in the mail? I figured I'd back up the 4S on Mountain Lion, then update the Mini to Yosemite, then crank up and restore the new iPhone 6 via Yosemite. Any thoughts welcome...including that it doesn't matter! Thanks!
