MacSentinel

Monitor Mac performance and inspect storage use

Meet MacSentinel

MacSentinel is a native macOS utility for examining system performance and storage use. It displays live CPU activity, memory pressure, disk information, network traffic, and other measurements, with treemaps that help explain where resources are going. It supports both Apple Silicon and Intel Macs.

Its storage tools inspect application leftovers and development caches, including material associated with Xcode and Docker, so users can review cleanup candidates. Integrations can expose live information to supported AI assistants, with approval before changes. MacSentinel is useful for developers and other Mac users who want to investigate a slow machine or understand disk usage from a single desktop interface.
