Why each option
On macOS, .dmg files are disk image files that must be mounted as virtual drives before their contents, typically applications or installers, can be accessed and installed.
.pkg files are installer packages that execute directly and do not require mounting; they manage the installation process themselves.
.zip files are compressed archives that are decompressed, not mounted, to access their contents.
.app files are application bundles that are executed directly and do not need to be mounted for installation; they are often dragged to the Applications folder.
.dmg files are Apple Disk Image files that act as virtual disk drives; they must be mounted by the operating system to access their contained applications or installer packages for installation.
