unpkg

What is unpkg?

unpkg is a native macOS utility for unpacking Apple installer packages so you can inspect or extract their contents without performing an installation. It is published by Tim Douglas and is designed for people who want to look inside .pkg and .mpkg files, pull out a specific app component, or examine package contents before deciding whether to install them. The app uses a simple drag-and-drop workflow and saves extracted files into a regular folder instead of placing them around the system. That makes it useful for troubleshooting, software inspection, and recovering individual files from installer archives. unpkg is a focused desktop helper rather than a package installer, so it is best used when you want access to package contents without changing your Mac.

Key features

• Open and extract .pkg installer packages without running them
• Extract .mpkg metapackages and nested package contents
• Use drag and drop to unpack packages quickly
• Save extracted files into a normal folder for browsing and copying
• Inspect installer contents before deciding whether to install software

Safety overview

Status: Mostly safe

unpkg is intended to read installer packages and extract their contents to a folder you choose, which is a normal use case for this kind of utility. It does not function as an installer, but the files you extract may include apps, scripts, extensions, or other components that should be treated with the same care as the original package. Use it to inspect or recover files, and only open or install extracted items if you trust where the package came from.

Recommendation: Keep unpkg if you sometimes need to inspect installer packages or pull out files without installing them. If you never work with .pkg archives, you can remove it without affecting macOS beyond losing that extraction convenience.
