On the old version, iPhoto, this couldn’t be stopped without breaking out the automator and making a more complicated fix. Â Fortunately, Photos has made this much easier to stop.
How to Stop OS X on a Mac from Opening the Photos App Whenever an SD Card, iPhone, or Tablet is Attached
- Connect the device or memory card to the computer that brings up Photos.
- When Photos pops up, go into the program (you may have to click the “Getting Started” stuff if you’ve never used it)
- At the top-left of the Photos window, you’ll see a box that says “Open Photos for This Device.” Â The box is checked by default. Â Uncheck it.
- Done!
- Now you’ll have to follow this same process for each device that opens photos. Â So if you unchecked it for an SD card, you’ll also have to go in and uncheck the box the next time you connect your iPhone, tablet, etc. Â It takes a few minutes, but once you’re done, it’s done forever. Â Phew!
You’re welcome 🙂
