BBB MacOS Security & Privacy Settings

If the first time you use BigBlueButton with a MacOS computer microphone, camera or screen sharing does not work, this may be due to incorrect security settings.

Security & Privacy Settings in MacOS Catalina for BigBlueButton
Settings => Security & Privacy

Check that the browser you are using is checked so that your microphone works for a BigBlueButton conference. To use the camera, check the settings in the "Camera" menu. If you want to share your screen, the settings under "Screen Recording" are decisive.
