The feature that allows you to preview a file quickly on a Mac is Quick Look. Quick Look provides a convenient way to view the contents of files without needing to open the associated applications. By selecting a file in Finder and pressing the spacebar, users can instantly see a preview of the file, whether it’s a document, image, video, or presentation. This functionality makes it easy to check the content of files without interrupting the workflow or dealing with the overhead of launching an application.

Finder Preview is not a recognized term for a specific feature on the Mac, and while Finder itself is the file management application, it does not include a separate preview function distinct from Quick Look. Spotlight Search is used primarily for searching files and applications on the Mac rather than previewing their contents. Mission Control is designed for managing open windows and desktop spaces, not for file previews. Thus, Quick Look stands out as the definitive feature for this purpose on the Mac.
