When mounted, it verifies the integrity of the installer using cryptographic signatures before the user can proceed. Unlike the seamless, delta-based updates delivered through the System Preferences panel, the DMG provides a portable, offline, and reusable installer. It can be written to a USB flash drive to create a bootable installer, archived on a NAS for a fleet of office Macs, or used to perform clean installations on multiple machines without re-downloading the 8GB+ file each time. In essence, the DMG represents user agency and control over the upgrade process, a counterpoint to Apple’s preferred “automatic” model.
