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 choos what you'd like to share.
Issue: GlobalMeet does not have permission to access your screen
Why? The first time you start screen share on macOS Catalina or Big Sur (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.
- Click the Lock button to allow updates.
- 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.
