If you are running macOS Catalina — version 10.15 — or later, you must grant access to the new Screen Recording Permission in order to share your screen during a dscout Live session.  Changing this security setting requires you to restart the Chrome browser, so be sure you complete this and any other readiness checks more than 24 hours before your session.

How to grant access to Chrome Screen Recording Permission

1. Manually open System Settings
2. Click on Privacy & Security
3. Scroll down and choose Screen & System Audio Recording in the sidebar
4. Click the box next to Google Chrome or Microsoft Edge (select the browser you'll be using for your session) to allow screen sharing for your dscout Live session. 
5. A pop-up should appear indicating that Chrome or Edge will need to be quit before it is able to record the contents of your screen.  Click "Quit Now" to exit out of all running instances of Google Chrome.
6. Reopen your browser and finish your Live To-Do List!

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