Every time you connect a camera to your Mac, or insert a memory card, the new Photos app opens automatically.
That’s great if you use
the new Photos app. But what if you still prefer iPhoto, Aperture, or
Lightroom because they have more features? In that case, Photos popping
open all the time is just an annoyance.
The
solution: Once Photos opens, look for the “Open Photos for this device”
checkbox in upper left. Turn it off. You have to do that for every
memory card and every camera, but only once apiece. After that, Photos
will keep its peace.
(Note:
If you’ve never opened Photos before, you have to click past the
Welcome screens, and from there to the Import tab, to see the “Open
Photos for this device” box.)
