EasyDMG is a native macOS utility that automates installing applications distributed as DMG disk images. Once configured as the default DMG handler, it mounts disk images and copies applications to the designated installation folder. The application performs macOS Gatekeeper security checks before installing software. Verified applications can install automatically, while unfamiliar developers trigger configurable warnings. After installation, EasyDMG unmounts the disk image and can move the original DMG to the Trash. Users can choose installation destinations, progress notifications, and application launch behavior. Existing applications can be replaced automatically or updated with confirmation. For complex installers containing packages or multiple applications, EasyDMG falls back to manual handling. It also supports automatic updates through Sparkle.
