I've been using iPhoto for years and to delete the photos from the iPhone there was a delete button that I would click and like magic the photos would delete off the phone. Now I have the terribly named Photos app (how useless is that app name when you are trying to find answers online?) and although I have checked the box saying "delete items after import" but it only deletes the most recent photos imported. I want ALL 1500 PHOTOS deleted. Where's the delete button? iOS 9, 10.10.5 I know I am not the only person who's ran into this problem but like I said about Photos terrible name, searching online for answers about "Photos" is endless.
