# NSExtensionServiceFinderPreviewIconName

The name of an icon for display when the extension appears in the Finder Preview pane and Quick Actions menu.

## Discussion

Discussion This key is used in conjunction with the NSExtensionServiceAllowsFinderPreviewItem key. Set the NSExtensionServiceFinderPreviewIconName key’s value to a system icon name or the name of an icon in the extension bundle. This icon should be a template image: a monochromatic image with transparency, anti-aliasing, and no drop shadow that uses a mask to define its shape. For design guidance, see Human Interface Guidelines > macOS > Custom Icons. If no icon is specified, a default icon is used.
