So, I've been using image capture to upload photos and videos taken on my iphone, to my rMBP, and I've never had any problems. But since yesterday, whenever I plug in my iphone (to the usb on MBP), image capture loads the images just fine, but, for some reason.. all the images are just gone after about a minute, and I get a message saying 'no camera or scanner detected'! I've tried rebooting the iphone and plugging and unplugging the usb cable, but nothing is working. BTW, I have a mid 2014 rMBP and an iphone 6s plus. Can anyone please help?
