You want to show a video in a Teams meeting on your MacBook or iMac, but the others hear no sound. On a Mac, Teams has to install an audio driver the first time before it can share computer sound, and macOS has to give Teams permission to record your screen and system audio. Below you'll read how to set up both and what to do if it still stays silent.
Share computer sound
- In the meeting, select Share.
- Turn on Include computer sound.
- The first time, Teams asks to install an audio driver. Select Install and enter your Mac password.
- Choose the screen or window to share. The sound now goes along.
Only start the video after you've started sharing. That way you're sure the first seconds aren't lost. Button names may differ slightly between Teams versions; the general steps are also in share your screen in Teams.
Why a driver?
On Windows, Teams can capture your computer's sound directly; one switch is enough there, as you can read in share computer sound in Teams. macOS doesn't simply allow that. That's why Teams installs a virtual audio device, which you'll find as Microsoft Teams Audio in the sound settings. Teams sends your Mac's sound through that device to the meeting. You don't have to select it as output yourself: Teams handles that while sharing.
macOS permissions
Teams needs permission to share your screen. Go to System Settings > Privacy & Security > Screen & System Audio Recording and turn on Microsoft Teams. On older macOS versions this section is called Screen Recording. Then restart Teams. Recent macOS versions occasionally ask again whether Teams may keep recording your screen; confirm it when they do.
If the others only see a black area instead of your screen, this permission is usually missing. More causes are in black screen when sharing your screen.
Tips for good sound
- Set the volume of the video itself to a normal level. What you hear, the others hear at roughly the same volume.
- Wear headphones, so your microphone doesn't pick up the sound from your speakers a second time.
- Want to play live music through your microphone, such as an instrument? Use music mode in Teams instead of computer sound.
- Showing a video from YouTube or Stream? Share the browser window rather than your whole screen. That way the others don't see your Mac's notifications.
Still no sound?
- Check that your Mac isn't muted and that the video plays in the right app.
- Stop sharing and start again with computer sound on.
- Update Teams and macOS, and restart your Mac after installing the driver.
- Check in System Settings > Sound whether Microsoft Teams Audio is in the list. If it isn't, share again with computer sound so Teams reinstalls the driver.
- Suddenly hear nothing yourself after sharing? Select your regular speakers or headphones as output again in the sound settings.

For admins
Installing the driver requires admin rights on the Mac. If your users work with a standard account, the installation fails and the meeting stays silent. In that case, roll out the audio driver centrally together with Teams, via Intune or another Mac management platform. You can't fully pre-approve the screen recording permission: macOS lets the user confirm it. With a configuration profile (PPPC) you can make sure that users without admin rights are allowed to give that permission.
