Note: If you later disable the Screen Recording permission from System Preferences on your Mac, you'll need to re-enable it again in the future. You should now be able to share your screen. Open your browser and rejoin your call in the classroom. Note that when you click Quit Now, you’ll quit the classroom as well and will be disconnected from your tutor or student for a couple of seconds.

across the Messages On macOS, you can share your screen with a third party, provided they use a Mac and are signed in to iMessage with an Apple ID. The easiest way to share your screen or request another user’s screen display is to use the Apple Messages app.

You will not be able to share screen until you quit and restart your browser. Use the Messages app to share screen on your Mac. You may need to click the unlock icon in the bottom-left. In the Screen Recording section click the checkbox next to Your Browser Icon to allow screen sharing during your lessons. If you don’t see the screen above and still can’t share your screen, manually open System Preferences on your Mac, click the Security and Privacy icon, and then choose Screen Recording in the sidebar. When you see the following screen, click Open System Preferences.

When you try to share your screen during a lesson on macOS Catalina 10.15 or later, you’ll be asked to enable Screen Recording for Google Chrome by your computer.
