We have a Macbook Pro for pretty much everything except playing solitaire (that's what the ancient XP PC is for.) My wife is an iPhone user, so we have tied her AppleID to both the Mac and the phone. I'm looking at moving into the iPhone cult real soon now, and am wondering how the whole iCloud, iTunes, and iOtherThings works when two different AppleIDs use the same Macbook. I think you can set up family sharing and do everything underneath a single ID, but is it possible to keep two logged in users separate so I can see my own emails, calendar, photos, and music and my wife can see her own? My experience with Apple is the answer will probably be "Yes, it's possible...but it's tricky."
