Extensions

macOS provides a customizable way for the feature-set of applications to be extended via plug-ins called “Extensions.” Typically, extensions are Apple-provided, or come from 3rd-party developers. However, starting with macOS Mojave (v10.14), users can make their own macOS extensions by using the “Quick Action” Automator template to create workflows that are automatically installed as macOS extensions when the workflows are saved.

By default, user-created “Quick Actions” are auto-saved into the Services folder in the user Library folder and may be managed by the user in the Extensions system preference pane in either the Touch Bar or Finder extension categories.

To access the Extensions system preference pane, open the System Preferences app by selecting “System Preferences…” from the Apple menu (), and then choose “Extensions” from the app’s “View” menu.

Touch Bar Quick Actions

Installed Quick Actions for the Touch Bar can be managed by selecting the Touch Bar category in the extension categories list on the left side of the preference pane window.
