What is a .MPKG file?
An MPKG groups several macOS installer packages into one.
- Did you know
- An MPKG lets one installer run a bundle of separate packages.
- A meta-package is an installer that bundles several individual .pkg packages, letting the user pick which components to install.
- Inside it a Distribution.dist XML document lists the sub-packages and any scripts the macOS Installer should run.
- What Analyser reads
- Open more archives, packages and installers: macOS XAR/.pkg/.mpkg installers (member list), Windows .msu updates (CAB), Snap SquashFS packages, Flatpak bundles, StuffIt (.sit/.sitx), lzop (.lzo) and Brotli (.br) streams, Java Web Start (.jnlp), and the .tlz/.tbz/.tz compressed-tarball shorthands.
- Depth of analysis
- .MPKG is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .MPKG file
- Drag a .MPKG file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
