Questions
Do I need the Helper?
Not for most of Stat Sentry. The Helper reads temperatures, fans and power, other users' processes in the top lists, CPU and GPU clock speeds, and a week of history; everything else works without it. Read what the Helper adds.
Why can't Stat Sentry show my Wi-Fi network's name?
macOS shows Wi-Fi names only to apps allowed to use Location Services. Click Show Name in the Network panel and allow it. Stat Sentry never reads your location.
Some temperatures are missing or have no name.
Temperatures come from the Helper, so without it the Sensors panel asks you to turn it on. With it, Apple doesn't document which sensor is which, so names come from a table per chip. Send a report from Settings › Support: it lists every sensor your Mac has, which is what I need to name them.
How much CPU does Stat Sentry use?
Usually around 1–3% of one core with the panels closed. Hidden menu bar items and panel sections aren't measured at all, and a longer update interval in Settings › General lowers it further.
Can it control fans?
No. Stat Sentry only reads. Writing to the Mac's system controller isn't something an App Store app should do.
Which Macs are supported?
Macs with Apple silicon, running macOS 26 or later.
