When I try to start screen sharing on macOS 10.15, the system prompts an error of no permission to record. What should I do?

Starting from macOS 10.15, some users may experience an issue with the sharing permission compatibility. It can be fixed in the following steps:

1. Go to System Preferences > Security & Privacy > Privacy.

2. Deselect the option. If you are using VooV Meeting, you will be asked whether to exit. Click Later, and then select the option again. If you are using VooV Meeting, you will be asked whether to exit again. Then, click Later and check whether the screen can be shared.

3. If the problem persists, try restarting the computer.

4. If the problem still persists, right click and select Show in Finder, delete the VooV Meeting app, and check whether the app is still displayed in the list.

• If yes, continue to delete until an unselected VooV Meeting app appears in the list, and then select it.
• If no unselected VooV Meeting app appears in the list after deletion, you can reinstall VooV meeting to fix the problem.

What should I do if the screen turns black or gray during screen sharing?

There are several causes of this problem:

Black screen caused by pause, with a message displayed in the center of the screen

Solution: the problem will be fixed when the sharer clicks Resume Share or maximizes the shared window. Check whether "xxx paused share" is displayed on the black screen:

If so, check whether the following message is displayed on the topbar:

• "xxx has paused screenshare"
• "Share paused. Bring your shared window to the front."
• If the sharer's topbar displays "xxx has paused screenshare", check whether the sharer clicked Pause.
  
  
• If the sharer's topbar displays "Share paused. Bring your shared window to the front." , check whether the sharer minimized the shared window.

Partial or full black/gray screen caused by window occlusion

Solution: the problem will be fixed when the sharer removes the occlusion of the shared window.
Check whether the shared window is occluded by another window. For some device models (for example, Windows 7 PC), the occluded part of the window will be displayed as a black or gray screen on the viewer's side.

At this time, the sharer's topbar will display "Window obscured. Bring your shared window to the front.". This helps determine whether the problem is caused by window occlusion, and if this is the case, the problem can be fixed when the sharer removes the occlusion of the shared window.

Black/Gray screen caused by other issues

If the problem is caused by other issues, contact Online Support for assistance.
