Stat Sentry
Free and optional
Stat Sentry Helper
A small system service that runs with elevated permissions, so Stat Sentry can show information from every user on your Mac. It only reads, never changes anything, and only answers Stat Sentry.
What it adds
- Temperatures, fan speeds and what the whole Mac draws, in the Sensors panel, the menu bar and widgets, and the temperature alerts.
- Processes from every user in the top lists, including WindowServer and kernel_task, instead of only yours.
- CPU and GPU clock speeds, and how much power the CPU, GPU and Neural Engine use, in the CPU and Sensors panels.
- A week of history for the CPU, Memory and Sensors graphs, recorded once a minute even while no one is logged in. Off until you turn it on.
Everything else, including drive health and the other alerts, works without it.
Install
- Download the disk image and open it.
- Drag Stat Sentry Helper to Applications, then open it from there.
- Click Install Helper.
- macOS asks you to allow it in System Settings › General › Login Items & Extensions. Turn it on there.
- Stat Sentry connects by itself. Settings › Helper says “Helper is running”.
Uninstall
Open Stat Sentry Helper and click Uninstall Helper. It asks for Touch ID or your password, deletes the history, and removes the service. Then move the app to the Trash.
Safe by design
- Signed with a Developer ID and notarized by Apple, so macOS checks it before it runs.
- It answers only Stat Sentry and Stat Sentry Helper, signed by the same developer, and Stat Sentry checks the Helper the same way. macOS starts it only as the developer signed it.
- It never goes online, and stores nothing but the history, when you turn it on.
- It runs only while something asks it a question, or all the time while history is on; launchd starts it.
