If your camera is supported, and you followed all of our setup instructions, and Dragonframe can’t seem to talk to it… it may be a permission issue. There was probably a point, when you first ran Dragonframe on macOS Catalina, that it asked if Dragonframe could access Photos… and you said ‘no’.

Dragonframe doesn’t actually access your Photo library, but for some reason macOS Catalina requires that permission in order for it to talk to your camera. To resolve the issue, go to the computer’s System Preferences and open the Security & Privacy section. Click Photos on the left, and then find Dragonframe on the right, and make sure the box is checked to give Dragonframe that permission.

If that doesn’t work, please try the 4.2 development build.
