DMG2IMG is a command-line tool that converts Apple compressed DMG (disk image) archives to standard HFS+ image disk files. The tool supports multiple compression formats including zlib, bzip2, and LZFSE compressed DMG images. The utility provides various operational modes through command-line options including silent mode, verbose output levels, debug mode, and partition listing capabilities. Users can extract specific partitions using the partition number option or convert entire disk images. The tool requires specific development libraries for full functionality: zlib1g-dev for zlib support, libbz2-dev for bzip2 support, and libssl-dev for vfdecrypt functionality. LZFSE decompression support requires the separate LZFSE library installation. DMG2IMG operates through standard input/output redirection and supports both interactive and batch processing modes. The converted output files can be mounted or opened using platform-specific methods as detailed in the documentation. The project is maintained as an open-source solution with ongoing bug fixes and security enhancements, building upon the original work by vu1tur.
