Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Andy,
Thanks for coming back to us. Please also make sure the **Media (Camera, microphone, speakers)**button via your profile button on the top right -> settings- > permissionsin Teams is checked:
Meanwhile, does Teams listed under Cameratab of Security and Privacy? If the problem persists, you can also try to upgrade your Mac OS version to see if it can help.
Best Regards,
Sylvie
