I am using Solar Eclipse Maestro 1.8.5 (100) on macOS 10.12.5 with my Nikon D7200.
Launching SEM it does appear to detect the camera, as I can select (from the Camera menu) Live View, Available Properties, Battery Levels, Check Settings, Benchmarks, as well as the Exposure, FOV, and Sampling Calculators. Also the other items on this menu are greyed out (including Push Button). I can run all these items EXCEPT Check Settings. When I run Check Settings, the app appears to open a window showing a progress bar (similar in appearance to the Benchmarks window), but no progress is made and the app locks up.
Any suggestions?
