UninstallPKG is a free Mac application designed to completely remove unwanted packages (file extension .pkg) and their installed contents from your system. It's particularly useful for reclaiming disk space by removing unused functionality, such as printer drivers or applications you no longer use. The app can also clean up leftover files from partially manually removed applications.

Key Features

UninstallPKG allows you to remove all associated files of a package at once, such as the 37,290 files associated with Office 2016, or entirely uninstall plugins like Java or Flash. It ensures a thorough removal process by also deleting application-generated files, removing the application from the Dock and Login Items, and erasing related preferences.

Safety Considerations

While UninstallPKG is designed to be safer than other uninstallers by avoiding the removal of files used by other packages, uninstalling packages is inherently risky. Users are warned to only remove packages corresponding to applications or functionality they no longer need.

System Requirements and Availability

UninstallPKG requires macOS 10.14 'Mojave' or later and is available in English, Simplified Chinese, and partially in German. The application is free to download and use, with a size of 3.2 MB.

Usage Instructions

1. Download UninstallPKG from the official website.
2. Move the application to the Applications folder to avoid a quarantine warning.
3. Launch UninstallPKG to view installed packages, including their identifier, filename, installation date, size, and version.
4. Select a package to view its contents and choose 'Uninstall Package' to remove it.
5. Confirm the removal in the subsequent warning dialog to complete the uninstallation process.
