Why convert DMG to IPSW?
A .dmg is a distribution container for macOS applications and installers. An IPSW is a ZIP-based firmware archive for iPhone, iPad, Apple TV, and other Apple devices - it contains the iOS or iPadOS operating system image, signed per device model and firmware version. These two formats serve entirely different platforms and purposes with no overlap.
