What is Apple disk image?
A macOS disk image; extraction depends on its filesystem and compression variant.
Server processing uses engines we host. Availability depends on the deployed engine and supported file variant.
Technical details
DMG commonly uses Apple's UDIF disk-image container, which stores a block map and may compress or encrypt image data. [1]
Background and compatibility
Apple disk images are commonly mounted as virtual volumes on macOS; a DMG may wrap a filesystem image rather than a file-by-file archive. [1]
