can't stop working.

Hello.

Run openmv ide 2.0.0 on macOS 10.14.1.
If click start button and run the example(find-barcode) file, it will start normally. but if click stop button, the camera(M7) LED will light up in white and ide and camera is freezing.
Removing openmv ide and reinstalling a new one is the same phenomenon.
What should I do?

And fails to update the firmware.

This issue is related to some USB commands being joined when sent to the camera. I can cut another version of the MAC IDE that may fix the issue. I can do this tonight if needed. Otherwise, if you have a windows or linux VM things work more smoothly on that. We’ve noticed a small percentage of Mac machines join USB commands going to the OpenMV Cam causing problems.
