In the Apple macOS operating system, a package is a file system directory that is normally displayed to the user by the Finder as if it were a single file. Such a directory may be the top-level of a directory tree of objects stored as files, or it may be other archives of files or objects for various purposes, such as installer packages, or backup archives.
