About:
dmg2img is a command-line utility designed to convert compressed Apple DMG (Disk Image) files into standard, mountable IMG images. It effectively handles the proprietary compression algorithms used by Apple, allowing users to access disk image content on non-macOS systems. This tool is essential for data extraction and forensic analysis of macOS-generated disk images in Linux environments.

Key Features:

Converts compressed DMG files to IMG format
Supports various Apple compression types (ADC, Bzip2, Zlib)
Lightweight, fast, and command-line driven
No dependencies on macOS libraries

Use Cases:

Extracting files from macOS disk images on Linux systems
Forensic analysis of DMG files without access to a Mac
Converting legacy DMG archives for use in virtual machines

Alternatives:

hdiutil – Native macOS tool; requires a Mac, whereas dmg2img runs on Linux.
dmg2img – The original tool; dmg2img is a fork with bug fixes and modern compiler support.
