Finding a corrupt photo so I can delete it
When I try to sync my iPhone 6S to Photos on my Mac, 2 (possibly) corrupt photos cannot import. Under the "New Photos (2 photos)" label I can see 2 gray squares that contain a default photos icon (2 overlapping rectangles).

Any clues about how to find the offending files and delete?

The error in Photos says "Unreadable Files: 2" and the error panel says "The operation couldn't be completed. (co…". Unfortunately the panel cuts off the rest of the error text.
