Set default import program from camera in OS X
Forgive me if you all know this, but I didn't. There is an application in the Applications folder called Image Capture. You can set the default program for different cameras. I use Lightroom for an M9 and iPhoto for the X100. No doubt that too is crazy, I know. I was frustrated by iPhoto launching first everytime I connected the M9 card. Now LR starts up.
