mydiskdmgcdr

mydiskdmgcdr is an open-source, cross-platform command-line utility for working with disk image files in DMG and CDR formats. It provides creation, conversion, mounting, and burning capabilities to support macOS-centric workflows on Linux and Windows as well.

Formats and capabilities: The tool can create encrypted or compressed DMG images from directories or files, convert between DMG and CDR/ISO representations, mount images for inspection, extract contents, and burn images to optical media via integrated burning libraries. It also supports checksums for integrity verification and scriptable batch operations.

Implementation and design: mydiskdmgcdr is implemented in C++ with optional bindings for scripting languages. It relies on libraries such as libdmg for DMG handling and libburn (via libisoburn) for burning. The project emphasizes a consistent interface across platforms and aims to minimize platform-specific quirks.

Availability and history: The project was released in 2022 under a permissive license. Development is community-driven, with regular releases and an issue tracker for enhancements and bug reports. As of 2024, several stable releases exist and the project maintains compatibility notes for different macOS versions.

Limitations: Some DMG features, such as APFS-specific metadata or certain encryption schemes, may not be fully replicated in CDR outputs. Windows support is limited and certain macOS-only workflows require native macOS tooling. Performance depends on hardware and I/O throughput.
