        I have some ImageCapture software (connects to an external Canon Camera) that is not working under 10.15.

        Now under 10.15.2 Beta (19C32e) a call to requestOpenSession does not respond with device:didOpenSessionWithError:

         

        To be clear...

        the software runs under 10.14... camera connects, can take pictures on the camera and via the macOS software.

        the software does not run under 10.15 (from the earlier OS build) or out of xocde directly on 10.15. In addition looking through the viewfinder of my camera (Canon D650) it says "busy"... and the rear display is off (this is different to 10.14).

         

        Observation under 10.15.2 Beta (19C32e)...   deviceDidBecomeReady is no called either... probably a sympton of the Open not working?

         

        I can see the device from the device browser...

        Interestingly running the ImageCapture software built into macOS does show the camera and lists the images on the camera.

         

        Posting message here because I don't know what to do next. Any clues or advice welcome.

        Thank you in advance for suggestions.

          Update.

           

          I have subsequently performed a build for 10.15... this has changed the behaviour of the application and deviceDidBecomeReady: is now called.

          The call to "requestTakePicture" seems to have no affect. I am teathered to the camera.
