If you're a Windows or Linux user, you can probably safely skip reading this post. If you're an Apple user, however, you know exactly how annoying it is to see the OS X Photos app open every single time you plug in a camera or a smartphone. It's ultra-simple:
• Launch a 'Terminal' session
• Enter the following line: defaults -currentHost write com.apple.ImageCapture disableHotPlug -bool YES
It’s the “Yes” that turns off the feature, so if you replace it with “no” it will start popping up every time again.

And for the record, I actually think OS X Photos is a pretty solid program for basic photo flow, but I almost never import directly into it and having that dialog pop up every single time gets pretty tedious.
