How to fix screen sharing in Microsoft Teams on a Mac

Sharing screen in Microsoft Teams is a powerful tool that allows you to hold presentations, share important notes or distribute useful audio files with colleagues.

In this guide, we’ll walk you through how to screen share in Teams on desktop or mobile devices.

Trouble with Teams sharing your camera, microphone or screen?

Occasionally, neither Microsoft Teams nor macOS prompts to share your camera, microphone and screen. That means Teams cannot access the camera and microphone and cannot screen share. Without these permissions in place, your Mac may show a spinning wheel in Teams. You can manually set up access by following these steps.

How to enable Privacy Settings on Mac
