Ghost Buster Pro
A lightweight Mac App Store utility from Sascha Simon that scans for support files, preferences, and caches left behind after you remove applications—aimed at users who want a fast, consent-based cleanup without a full system optimizer.
Typical Mac workflow
You launch Ghost Buster Pro and the search starts immediately. The app looks for data tied to applications that are no longer installed, groups what it finds, and presents the results for review. Nothing is removed automatically: you choose which items to delete and which to keep, which reduces the risk of wiping data you still need from a renamed app or a portable install.
If a result is a false positive, you can add it to a blacklist so those paths are excluded from future deletions. Version 5.0 added the ability to ignore specific search results and manage ignored entries in Settings—a workflow that remains available in the 5.1 line. The interface stays deliberately minimal: scan, review, delete, done.
Privacy, platform, and version 5.1.0
Sascha Simon states that the app collects no user data and is built without third-party analytics frameworks. Ghost Buster Pro is sold only through the Mac App Store for $1.99, supports Family Sharing, and is localized in ten languages including English, German, French, Spanish, and Simplified Chinese. Version 5.1.0, released in early July 2026 per the App Store, focuses on bug fixes and stability improvements; it requires macOS 15.6 or later. It targets orphan leftovers from deleted apps rather than deep system maintenance, duplicate finding, or uninstalling apps that are still present.
