What does the status bubble in GPGMail indicate?

In Mail.app > Preferences > GPGMail at the top you find a colored bubble indicating if GPGMail is running fine. Clicking the bubble will take users to this very KB-article.

Green: Everything is groovy - all systems up and operational

Red: MacGPG 2 not found - please reinstall GPG Suite

Orange: GPG not working as expected

To resolve this, open Terminal.app and execute the following commands one after the other:

launchctl unload /Library/LaunchAgents/org.gpgtools.Libmacgpg.xpc.plist; sleep 5;
launchctl load -w /Library/LaunchAgents/org.gpgtools.Libmacgpg.xpc.plist

Should your problem persist, open System Preferences > GPG Suite > Send Report and describe your problem in as much detail as possible. We recommend to include the Debug Log. We will then help you out getting your setup fixed.
