  • How to enable screen sharing on my Mac?

  • What would be the connection of an upgraded macOS system and issue with screen sharing/recording?

If you were able to share your screen before when using Therabyte but suddenly you’re unable to - it is likely due to the recent upgrade Apple has made for the macOS new security and privacy features. We have no control over the settings that Apple/macOS have implemented. 

In this case, if you are running a macOS Catalina version 10.15 or later - you must grant access to the screen recording permission in order to share your screen again.

Here’s a sample step by step instruction in order to enable “screen sharing”:

1. When you first join a meeting on macOS Catalina, you’ll be asked to enable the Screen Recording permission for Google Chrome.


When you see the following dialog, click "Open System Preferences".

If you do not see the dialog above or you are unable to screen share, manually open System Preferences, click the "Security and Privacy" icon and then choose "Screen Recording" in the sidebar.

2. In the Screen Recording section click the box next to Google Chrome to allow screen sharing for your video calls. You may need to click the unlock icon in the bottom-left.

3. Next, click "Quit Now". You will not be able to screen share until you quit and restart Google Chrome.

4. Rejoin your video call. You should now be able to screen share!

If you have any issues, click the chat icon in the bottom-right of this page to chat with us.



Note: If you disable the Screen Recording permission from System Preferences, you'll need to re-enable it again in the future.
