macOS system permission

Some users on macOS may experience issues when attempting to share their screen on Chrome, as the capture stream can be blocked by system permissions. Sometimes, even after permissions are reset, screen sharing may still fail. To fix this, you’ll need to reset certain permissions and settings.

Granting permissions

Follow these steps to enable screen sharing on Google Chrome:

1. If AirSync is unable to cast, the browser displays an alert page with a link to System Preferences.
   
   
   
   
   
2. Follow the link to launch the Security & Privacy page under System settings. 
   
   
   
   
   
3. On the left panel, select Google Chrome to grant permission to record the contents of your screen. 
   
   
   
   
   
   (Optional) Make sure all other browsers that you are using with AirSync are also included and checked in the list.
   
   
   
   
4. Click Quit now to apply the changes. Note that the system will force-close the browser.
   
   
   
   
   
5. Re-launch the browser again and check if you can now successfully cast to AirSync.
