Table 1. Third-party support changes
Type of Software Previously supported version New version
Operating System Apple Mac OS Sierra (v 10.12) Apple Mac OS Catalina (v 10.15)
Note: When a leader launches the App client on a Mac OS Catalina v 10.15, and tries to perform AppShare, other participants can see only the leader's desktop. This issue is caused mostly due to security permissions of the operating system.
For AppShare to function correctly, you must enable Screen Recording on your machine as follows:
  1. Click the Apple menu.
  2. Click System Preferences > Security & Privacy > Privacy > Screen Recording.
  3. Click the lock icon to make your changes (you will need to enter your admin password).
  4. Click the check box next to the Cornerstone Classroom app client. A notification window appears prompting you to restart the app.
  5. Restart the app client.
  6. Try AppShare again.
