Whenever I put in my SD card, the Photos app opens automatically. I can set it to not open on a per-device basis, but since I format my SD card frequently that doesn't really help.

How can I stop this? I don't really ever want to use the Photos app at all.


Image Capture manages which app is launched for a device. You can disable this functionality entirely by running the following then logging out:

defaults write com.apple.ImageCapture disableHotPlug -bool TRUE

    +1 but I so wish you could micro-manage these settings :/ RCDefaultApp can still do it for older device types, but doesn't cover modern devices like SD Cards. – Tetsujin Mar 5 '17 at 8:54
