"Approval Request Sent" Message
I recently upgraded my iPhone 5s to iOS-9. I now receive (on my iPhone) a message as follows:
Approval Request Sent. To continue using iCloud on this iPhone, approve it from one of your other devices using iCloud or enter your iCloud security Code.
Sadly, I'm clueless as to what this is about. I suspect I've changed an iCloud setting in my iOS upgrade install. But I don't know what it's asking. I have a MacBookPro Retina (late 2012) as my main Apple device. But when I go there, (it's on OSX 10.10.5, I've no clue what I have to do to "authorize" what the iPhone is asking. So I worry, is this message from Apple, or is it some kind of malware?
MacBook Pro with Retina display, OS X Yosemite (10.10.5), 16GB RAM, 5GB Solid state "drive"
