If you are using a third-party program like Lightroom to manage your photos on your Mac, then you probably hate it just as much as I do when my iMac pops up the Photos app each and every time I put an SD card into the computer, or connect my iPhone to the Mac with a cord. It's one more thing you have to shut off before you can to what you need to do.
On the old version, iPhoto, this couldn't be stopped without breaking out the automator and making a more complicated fix. 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.” The box is checked by default. Uncheck it.
- Now you'll have to follow this same process for each device that opens photos. 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. It takes a few minutes, but once you're done, it's done forever. Phew!
You're welcome 🙂
