I've been receiving the below error message for quite some time now. It occurs when I plug in my phone to sync. The phone is authorized to use the computer and I never changed any settings before the message began appearing. I don't recall the exact point in time the message began popping up, but it may have been when I upgraded to Sierra.
The message goes away when I unlock the phone, but that's pointless as I've never had to do it in the past. Any help?
I have already tried resetting dialogue warnings per this article, but nothing has changed
