UninstallPKG 1.2.2 (the current 2026 iteration) is the definitive utility for Mac users who need to scrub “package” installs (.pkg and .mpkg) from their systems. Unlike standard app cleaners that look for app bundles, UninstallPKG digs into the macOS receipt database to identify every single file an installer placed on your drive—including hidden printer drivers, plugins, and deep system background processes.
As a grounded peer, I have great news: UninstallPKG is now 100% Freeware. While it used to be a paid application, the developer (CoreCode) made the software free of charge starting with the 1.2.x branch. Any site offering a “crack” or “license key” for this tool is distributing unnecessary and potentially malicious files. You can download the full, unrestricted version safely and legally directly from the official source.
Key Features:
-
Deep Package Inspection: Scans the internal macOS “receipts” to find every file associated with a specific
.pkginstaller. -
Safety Safeguards: The engine is designed to never remove files that are shared by other active packages, preventing accidental system instability.
-
Space Reclamation: Ideal for removing bulky, unused printer drivers, legacy Java versions, or Flash plugins that occupy gigabytes of hidden space.
-
Leftover Cleanup: Detects and removes “orphaned” files (preferences, caches, and logs) from apps you previously deleted manually.
-
Login Item Management: Automatically removes uninstalled background processes from your “Login Items” to speed up your Mac’s boot time.
What’s New?
-
macOS 15/16 Full Compatibility: Specifically optimized for macOS 15 (Sequoia) and the early 2026 builds of macOS 16, ensuring the receipt database is read correctly.
-
Modernized Search Heuristics: Improved logic for identifying files generated after the initial installation (like dynamic library updates).
-
UI Performance: A smoother, faster scrolling interface when dealing with systems that have tens of thousands of installed packages.
-
Freeware Transition: Version 1.2.x officially removes all trial limitations and payment prompts, making the “Pro” features available to everyone.
