How can I configure Apple Mail to always open calendar invites in Fantastical 2?

Typically in OS X dialogs, you'd:

  • Right click on file
  • Select Open With...
  • Choose the application
  • Select Always open files of this type option

However, this option isn't available in the Mail dialog.

How do I set this preference?

The OS X Default calendar app preference is set in Calendar.app's preferences. If you select Fantastical there it should yield the behavior you are looking for.

Calendar.app > Calendar > Preferences > General > Default Calendar App

    It doesn't "take" for me. I have set this but every time I close calendar.app and re-open it, is has changed the default back to itself.
