Gather must request permission to use your mic and camera, and to record screens for screen sharing. Here's how to check your system preferences to make sure you have a smooth experience in Gather.
For Mac Users
Open System Preferences and select Privacy & Security.
Check both Camera and Microphone to see if the Gather Desktop App or your browser has been granted permission. Make sure the padlock is unlocked to make your changes.
If you want to screen share in Gather, in Privacy & Security, scroll to Screen & System Audio Recording.
This will show the list of applications available to record your screen. Again, make sure the Gather Desktop App or your browser has been granted permission to record.
For more assistance, please refer to these instructions from Apple for setting permissions on an Apple Mac.
For Windows Users
Go to Start > Settings > Privacy > Camera.
First, make sure you allow access to the camera on your device.
Next, scroll down to Allow desktop apps to access your camera. Make sure this is toggled On and that you can see the browser you're using to access Gather listed below.
