I recently upgraded my Mac Pro from Yosemite to Sierra, and whenever I plug in my iPhone 6s, both iTunes and Photos will open as they should. However within Photos (and Image Capture), I get a "please unlock iPhone" message. When I unlock my iPhone, everything proceeds. While I do not get the "unlock phone" nag from iPhoto, however, my photo library has been converted to use Photos.
As per discussions at the Apple forums, I've reset my iPhone's network settings. This prompted a fresh "trust this computer" dialog on my iPhone, for which I clicked "trust". Unfortunately, this had no effect on Photos or Image Capture, which are still asking me to unlock the iPhone.
How can I get Photos and Image Capture to recognize this iPhone and stop asking me to unlock it?
- macOS Sierra 10.12.3
- Photos 2.0
- iPhone 6s running iOS 10.2.1
