If Microsoft Teams prompts you for access
Upon first time use, Microsoft Teams may request access to your camera, microphone and screen.
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.
- In the top-left corner of the Mac Desktop, click Apple menu then select System Preferences.
- The System Preferences window appears. Click the Security & Privacy icon.
- The Security & Privacy window opens. Click the Privacy tab.
- In the lower left of the window, click the padlock icon to make changes. Enter your Mac's administrator username and password.
- In the left column, click the Accessibility section. If Microsoft Teams is not listed on the right side, click the plus sign and add Microsoft Teams. Then check the Microsoft Teams checkbox.
Click the Camera section. Check the Microsoft Teams checkbox.
Click the Microphone section. Check the Microsoft Teams checkbox.
Click the Screen Recording section. Check the Microsoft Teams checkbox.
- Close the Security & Privacy window.
Quit Microsoft Teams and reopen Teams to enact these changes.
