How to Grant Access Permission for TeamViewer on macOS

1. Open the TeamViewer app.

2. Go to the Menu bar > "Help" > "Check system access".

3. Give permissions for all the settings that are "Denied" one by one.
4. You can check the example below to see what it means.

5. After that, the “Security & Privacy” window will pop up. Make sure you have the “Screen Recording” setting open.
6. Click on the lock icon in the bottom-left corner.

7. You may be prompted to enter the admin password. Enter it and press "Unlock".

8. Tick the checkbox for TeamViewer.

9. If a pop-up appears, press "Later". 

10. Go back to the "Review System Access Page". Now the "Screen Recording" setting is green ("Allowed").

11. You need to repeat the same process for other "Denied" settings. Once every setting is "Allowed", quit TeamViewer and open it again to apply the changes.
