PKGDMG

PKGDMG is a software utility designed to streamline the creation and distribution of macOS installer artifacts by bridging the PKG (package) and DMG (disk image) formats commonly used on Apple platforms. It provides a unified workflow for producing installer packages (.pkg) from application bundles, scripts, and resources, and for packaging those installers into ready-to-distribute disk images (.dmg) suitable for direct download or managed deployments. The tool targets developers, IT teams, and system integrators who require reproducible packaging processes.

Key features typically include packaging automation, integration with standard macOS tooling, and options for signing and verifying artifacts. By coordinating pkgbuild, productbuild, and hdiutil or their equivalents, PKGDMG aims to minimize manual steps and reduce human error in building distributable installers. It often supports scripted workflows, allowing continuous integration pipelines to reproduce builds across macOS environments.

On the format side, PKGDMG handles the creation of .pkg installers and the assembly of .dmg disk images, including options for compression, encryption, and partitioned or sparse-diff disk images. It may expose a command-line interface and optional programming interfaces to facilitate customization, license handling, and post-installation actions. The project emphasizes compatibility with Apple's packaging conventions and strives to provide consistent results across macOS versions.

In practice, PKGDMG serves as a resource for software developers and IT operations teams seeking standardized, auditable packaging workflows for macOS software distribution. As packaging requirements evolve, PKGDMG may evolve to support new formats, signing standards, and deployment scenarios.
