In order to properly use Vast Conference video conferencing on a MAC you must enable access for the camera, microphone, and screen sharing.
SETTING CAMERA AND MICROPHONE PERMISSIONS
From the apple icon on the top left corner of your screen, click on System Preferences. Then click the house-shaped icon called Security & Privacy.
A new Security & Privacy window will appear. Click the Privacy tab. From the left pane, scroll down until you see Camera. Highlight Camera. Find Vast Conference in the window to the right and check the box to allow the app access to your camera.
Follow the same steps for Microphone.
If your camera is still not being detected try the following options:
Closeout of any other applications that may be using the camera.
If you are using an external webcam with a USB cable, make sure it is securely connected to the port. Alternatively, try a different port.
Restart your computer.
MAC SCREEN SHARING PERMISSION
MAC users running Catalina OS or above are required to grant one-time permission to enable Vast Conference screen sharing.
When attempting to share your screen for the first time on Catalina, the following prompt will pop up on your screen. Click on Open System Preferences.
In the box that appears next, highlight Screen Recording and check the box next to Vast Conference to allow the app to record the contents of your screen.
MAC requires that you restart Vast Conference. Click Quit Now and your meeting will be restarted.
PARTICIPANT PERMISSIONS - Google Chrome
When joining a Vast Conference meeting from the browser, Google Chrome will need access to your camera and microphone so that the video conference runs properly. See above and choose Google Chrome for Camera and Microphone.
If a meeting participant using Vast through the web browser wants to share their screen they must also give Google Chrome access to Screen Recording.
