Apple's new security model requires admin access to use privacy related devices such as a camera or microphone.  We now have a PPPC (Privacy Preferences Policy Control) enabled in JAMF for all managed lab computers that allows a standard user to enable these resources.

When a student first sets up their account and launches the Zoom app and joins a meeting they will be asked to allow access. Please click "OK" to allow access. If you click "Don't Allow" you will need to follow the instructions below to enable access to the Microphone and Camera.

Open the System Preferences and open the Security & Privacy section.

This looks like this in Systems before Ventura - macOS 13...

Or it will look like this in Systems with Ventura - macOS 13...

Once in the Security & Privacy Settings select the Microphone section and ensure the Allow Check Mark / Slide Button is ticked next to Zoom.

If Zoom does not show up in this list, you will need to launch Zoom and join a meeting so the app requests to use the Microphone and Camera. 

Next select the Camera section and ensure the Allow Check Mark / Slide Button is ticked next to Zoom.

After making these changes, you should be all set to join a meeting with Zoom.
