DMG2IMG

DMG2IMG is a tool which allows converting Apple compressed dmg archives to standard (hfsplus) image disk files.

This tool handles zlib, bzip2, and LZFSE compressed dmg images.

Usage:

dmg2img [-l] [-p N] [-s] [-v] [-V] [-d] <input.dmg> [<output.img> | -]

or

dmg2img [-l] [-p N] [-s] [-v] [-V] [-d] -i <input.dmg> -o <output.img | ->

Options: -s (silent) -v (verbose) -V (extremely verbose) -d (debug)
         -l (list partitions) -p N (extract only partition N)

See the original README file for platform-specific instructions to open or mount the resulting output file.

Building

Required packages:

• zlib1g-dev (zlib support)
• libbz2-dev (bzip2 support)
• libssl-dev (only required for vfdecrypt, not needed for dmg2img)

LZFSE decompression support requires the LZFSE library which can be found at https://github.com/lzfse/lzfse/. As this library is not widely available on Linux distributions, it is not enabled by default.

To build dmg2img:

make dmg2img

To build dmg2img with LZFSE support:

make dmg2img HAVE_LZFSE=1

To build dmg2img with Address Sanitizer for debugging purposes:

make dmg2img CC=clang LDFLAGS=-fsanitize=address
