I only see a striped background when I use mmhmm

If you see our striped test pattern background instead of your presentation when you use Meet, Zoom, etc, mmhmm isn't able to communicate with the app you're using. Try the following:

  • Quit the app you're using (Zoom, Chrome, Firefox, etc)
  • Quit mmhmm
  • Start the app you were using
  • Start mmhmm

If that doesn't resolve the issue, open the Activity Monitor app and type "mmhmm" into the filter box. You should see two processes running, mmhmm and mmhmmAssistant:


If you don't see the mmhmmAssistant running and you're tech-savvy, you can start it by opening the Terminal application and pasting in the following, then pressing return:

launchctl load -w /Library/LaunchAgents/com.all-turtles.mmhmm.Camera.Assistant.plist
launchctl start com.all-turtles.mmhmm.Camera.Assistant

After running those commands, you can quit Terminal. You should then restart the app you were using with mmhmm (Zoom, Chrome, Firefox, etc) so that it can see our camera.
