Fixing missing Application in Catalina's Privacy Protection settings

Slack and Microsoft Teams did not show up in Catalina’s Privacy Protection settings, thus, I could not grant permission to capture the screen. I could solve the problem for both applications by completely removing the application and resetting Catalina’s internal settings.

Here are the detailed steps for Microsoft Teams on Catalina 10.15.7:

• Uninstall Microsoft Teams

• Delete any Microsoft Teams leftovers:

  1 2 3

  rm -rf ~/Library/Caches/com.microsoft.teams rm -rf ~/Library/Caches/com.microsoft.teams.shipit rm -rf ~/Library/Application Support/Microsoft/Teams

• Reset Catalina’s internal Privacy Protection “Screen Capture” settings. This will reset any screen capture permission that was granted to any application. In my case, other applications just asked again for permission without a problem.

  1	tccutil reset ScreenCapture

• Install Microsoft Teams again as normal

• After attempting to share the screen in a call, the Screen Capture permission requested should show up automatically
