DMG2IMG is a tool which allows converting Apple compressed dmg archives to standard (hfsplus) image disk files. This tool handles zlib and bzip2 compressed dmg images. USAGE: dmg2img [-l] [-p N] [-s] [-v] [-V] [-d] [] or dmg2img -i -o It is derived from dmg2iso v0.2c by vu1tur NOTES: 1. An equivalent command under Mac OS X would be: hdiutil convert -format UDTO -o 2. Under linux, the image disk file can be mounted with the commands modprobe hfsplus mount -t hfsplus -o loop /mnt [normally, only 'root' might be able to do this] 3. Windows users should be able to open the image disk file with UltraISO. Jean-Pierre Demailly COMPILATION: The default included Makefile is for Linux/gcc. The development files in zlib-dev and libbz2-dev are needed to compile dmg2img, and those in openssl-dev are needed to compile vfdecrypt. CHANGELOG: 1.0 3 August 2007 * Initial version 1.1 4 August 2008 * Fixed segfault bug occurring when decompressing certain dmg files beyond the actual end of the file (due to not correctly setting the size of the compressed parts ...) * Added slightly modified vfdecrypt utility from Weinmann-Appelbaum-Fromme in order to decrypt encrypted dmg files. 1.2 17 September 2008 * Fixed segfault bug due to buffer overflow (buffer sizes incorrectly set, resulting in insufficient memory allocation). * Fixed most compilation warnings - remaining ones are irrelevant with standard compilers. 1.3 19 September 2008 * Further fixes which (hopefully) enable dmg2img to work on dmg archives of arbitrary size, while reducing RAM usage a lot. * A lot of thanks to Alfred E. Hegge and Randy Broman for testing and reporting bugs. 1.4 5 April 2009 * Applied patch from Vladimir 'phcoder' Serbinenko which brings correct handling of 64bit integers in koly signature and plist data, and should enable dmg2img to work on huge archives > 4GBytes (tested by 'phcoder'). * Added support for dmg archives involving bzip2 instead of zlib compression (this has not received much testing yet, as those archives are still unfrequent). * Many thanks to Pierre Duhem for useful hints. 1.4.1 6 April 2009 * Fixed a bug in writing the output file that caused some DMG images to convert to a broken unmountable IMG image. 1.5 8 April 2009 * Fixed a bug in parsing plist for image partitions. * Added support for ADC-compressed dmg images. 1.5.1 11 April 2009 * Added missing zero block type. * Small fixes and clean up. 1.6 15 April 2009 * Added support for dmg images that only have binary resource fork but no XML plist. * Refined koly block processing. * Fixed a bug in finding the offset for the next compressed block when offsets are defined relative to the current partition. * Fixed broken progress indicator. * Added detection of images with GUID Partition Table and respective mount commands in linux. 1.6.1 12 August 2009 * Fixed a bug in handling large files on win32 systems. 1.6.2 24 March 2010 * Fixed a bug in processing a terminal block type. * Added periodic flushing of debug log file. 1.6.3 07 April 2012 * Added option -l to list partitions * Added option -p to extract only specific partition * Added support for a rare case scenario of koly block being at the the beginning of the image (thanks to Friik) 1.6.4 25 April 2012 * Compilation bugfix (Linux) 1.6.5 23 July 2013 * Fixed a bug in handling some types of dmg files 1.6.6 06 February 2017 * Fixed a crash on invalid block signature (thanks to Peter Wu) http://vu1tur.eu.org/dmg2img
