DMG Extractor

Purpose and scope: This tool provides programmatic access to the contents of Apple Disk Image (.dmg) files, targeting developers, IT admins, and security professionals who package macOS installers or offline archives. It supports encrypted and unencrypted images and yields a verifiable file tree for deployment, forensics, or data recovery workflows.
Conceptually, the tool parses DMG structures, decrypts volumes when a password is supplied, and writes extracted items to a destination. It generates a manifest of paths and preserves attributes where possible. Optional integrity Verification computes hashes to verify content.
Beneficiaries include software teams delivering macOS installers, IT operations performing offline deployments, and responders requiring rapid access to archived assets. The value lies in automation, reproducibility, and safe handling of encrypted images, reducing manual mounting errors.
Core features combine input validation, password handling, optional selective extraction, batch processing, and detailed error reporting. It does not mount volumes on host systems but outputs a structured directory for downstream tooling such as packaging or testing.
