MacSentinel for Mac

Find what’s slowing your Mac then clean it safely

MacSentinel is a native macOS performance monitor and cleaner designed to help you understand what is using your Mac’s resources and safely reclaim unnecessary storage.

MacSentinel provides real-time CPU and memory monitoring, process-level insights, and memory-growth detection so you can identify applications and processes that may be consuming excessive resources. Its visual monitoring tools make it easier to see what is happening on your Mac without relying on guesswork.

The built-in Smart Care system goes beyond generic cache cleaning. It uses more than 500 app-specific rules to identify unnecessary files and caches, including professional development and creative-work data such as Xcode DerivedData, iOS DeviceSupport files, Docker data, npm and Homebrew caches, and other application-specific storage.

MacSentinel is designed around a diagnose-before-clean approach. You can review what is taking up space before deciding what to remove, while the Custom Ignore List gives you additional control over files and locations that should be preserved.

The app also includes a full application uninstaller for removing apps together with their associated files, helping keep your Mac organized over time.
