This article shows the solution for Screen Sharing Issues related to Security and Privacy Settings on Mac OS Catalina.
To enable screen sharing on a Mac (OS Catalina) the user needs to change to the setting directly in the system preferences for security and privacy, then click the “privacy” tab.
After clicking the padlock on the bottom left to make changes, scroll to the screen recording settings. Check the box next to the preferred browser to allow the browser to access screen recording (to allow Collaborate Ultra to access your screen). Check the box next to Kaltura Capture to allow the recording application to access your screen.
