Screen sharing from the Mac desktop app appears to be working correctly to you, the person sharing, but others see a blurry, still image of what you first shared or possibly the screen where you choose to what you'd like to share.
Issue: GlobalMeet does not have permission to access your screen
Why? The latest version of macOS introduced more stringent security checks. The first time you start screen share on macOS Catalina (for example, after a system update), you're prompted to allow GlobalMeet to record your screen. If you're like many of us, you saw "record" and dismissed the alert - you were just trying to share, right? Unfortunately, you won't be asked again.
Resolution: Enable app permissions for GlobalMeet
You can update permissions in System Preferences.
Note: The desktop app has to restart to apply the change. If you're in the middle of a meeting, restarting will kick you out of the meeting. When the desktop app restarts, join the meeting again.
To allow GlobalMeet to access your Mac screen:
- Open System Preferences and then select Security & Privacy.
- Click Privacy and scroll to Screen Recording.
- In the list of apps, select GlobalMeet.
- When prompted to close GlobalMeet, click Quit Now.
- Restart the desktop app. Now you can screen share in meetings you join from the desktop app.
