okay, I got an iPhone 4, an iPhone 5, a MacBook Pro (2.6GHz Intel Core 2 Duo)
When I go to iCloud Account Setting and check out the devices I see different things:
on my Macbook, I see only the MacBook and the iPhone 5
on the iPhone 4, I see everything (including devices I have not listed above), but NO Macbook.
Everything runs my Apple ID. Everything runs the latest OS it can.
I expect the iPhone 4 to see the Macbook. I expect the Macbook to see the iPhone 4 plus the three other devices I have (again, not mentioned for brevity's sake).
What did I do wrong? If the 4 can see things but the Macbook cannot, then the problem must be with the MacBook, right?
