A Mac OS DMG file is a compressed disk image containing a specific Mac operating system installer, typically used for upgrading or installing the system on a Mac. Such a DMG file can be convenient if you want to upgrade macOS directly but can't download it using the Mac App Store or the System Update preference pane, or if you wish to create a macOS bootable installer.
