Activate GPG Keychain expert settings

Important: Please only proceed, if you really know what you are doing. The settings that can be activated are hidden for a reason. We don't want you to be stuck with a non-working version or unusable keys or insecure settings!

To activate expert settings open Terminal and paste the following line and press enter:

defaults write org.gpgtools.gpgkeychain showExpertSettings -bool yes

To deactivate expert settings again use

defaults write org.gpgtools.gpgkeychain showExpertSettings -bool no

This activates the following expert settings

  • Algorithm Preferences
  • allows removal of last self-signature
  • allows revocation of last self-signature
  • allows import of non-self-signed keys
