history
Project history and usage
dmg2img is a small command-line converter for turning Apple compressed DMG disk images into standard HFS+ image files. Its package-manager appeal is that it gives Unix and Windows users a narrow, scriptable way to inspect or convert macOS disk images without Apple's Disk Utility.
Project history
The original project is published from the vu1tur.eu.org tools page, whose dmg2img page describes the tool and carries the upstream changelog. The maintained GitHub tree says it imports the original dmg2img code and tarballs, while Peter Wu's maintenance branch adds bug fixes, security fixes, and other enhancements.
Adoption history
dmg2img became useful in packaging and recovery workflows because DMG files are common distribution containers for macOS software, but package builders and Linux users often need ordinary image output. Its small C utility shape makes it easy for package managers to ship alongside tools such as vfdecrypt.
How it is used
Typical use is a one-shot conversion from a .dmg input to an .img output, followed by mounting or extracting the resulting filesystem image with platform tools. The maintained README also documents optional build support for newer compression handling such as LZFSE.
Why package nerds care
Package nerds care about dmg2img because it is the boring glue that lets non-macOS build and forensic environments handle Apple's disk-image packaging format without a large desktop stack.
Timeline
- 2017: The upstream changelog lists dmg2img 1.6.7.
- 2020: The maintained GitHub tree records imported upstream code plus maintenance fixes.
Related projects
