Prevent Photos from opening when you connect an iOS device to your Mac

I connect my iPhone to my Mac for a number of reasons. Sometimes, I’m downloading an app from Xcode. Sometimes, I’m doing a backup, other times an iOS update. Sometimes I’m using QuickTime Player to create a movie, using my iPhone as a source.

When I plug my iPhone into my El Capitan driven Mac, I can count on one thing. Photo will launch. And if I’m doing a screen capture, Photos will keep launching each time I hit the end of a capture session.

Painful.

If you share my pain, read this, and suffer no more. Simple, but well hidden. Thank you Kirk!
