Share content in a meeting in Teams
To share your screen in a meeting, select Share content 
in your meeting controls. Then, choose to present your entire screen, a window, a PowerPoint file, or a whiteboard.

When you're done sharing, go to your meeting controls and select Stop sharing.
Share content on a Mac
If you're using a Mac, you'll need to grant permission to Teams to record your computer's screen before you can share.
You'll be prompted to grant permission the first time you try to share your screen. Select Open System Preferences from the prompt.
If you miss the prompt, you can do this anytime by going to Apple Menu > System Preferences > Security & Privacy.
Under Screen Recording, make sure Microsoft Teams is selected.
- Go back to your meeting and try sharing your screen again.
Note: If you're using Teams on the web, make sure you've also granted screen recording permission to your browser.
Include computer sound
Sharing computer sound lets you stream audio from your computer to meeting participants through Teams. You can use it to play a video or audio clip as part of a presentation.
To share sound, select Share content 
in your meeting controls and then Include computer sound (it's the switch on the top right of your sharing options). All sound from your computer, including notifications, will be audible in the meeting.
For more info, check out Share sound from your computer in a Teams meeting or live event.
Give and take control of shared content
Give control
If you want another meeting participant to change a file, help you present, or demonstrate something, you can give control to that person. You will both be in control of the sharing, and you can take back control anytime.
Note: When you’re sharing an app, only give control to people you trust. People you give control to may send commands that could affect your system or other apps. We've taken steps to prevent this but haven't tested every possible system customization.
On the sharing toolbar, select Give control.
-
Select the name of the person you want to give control to.
Teams sends a notification to that person to let them know you’re sharing control. While you’re sharing control, they can make selections, edits, and other modifications to the shared screen.
- To take control back, select Take back control.
Take control
To take control while another person is sharing, select Request control. The person sharing can then approve or deny your request.
While you have control, you can make selections, edits, and other modifications to the shared screen.
When you’re done, select Release control to stop sharing control.
