PLATFORM 1How hot, and which sensors
Thermals
How hot your Mac is running, right in the menu bar.
The CPU die temperature sits next to the clock. One click opens a split-flap board with every sensor, your cores, fans and memory, and the apps behind the heat.

PLATFORM 2Who is making it hot
PLATFORM 3Where the memory went
Sample readings, heating up and cooling down, played back at four times speed. The app reads your own Mac's sensors.
TICKET MACHINE
-
Install with Homebrew (or download the zip and drag Thermals to Applications)
brew install --cask radkode/thermals/thermals -
Open Thermals. It lives in the menu bar, with no Dock icon. Choose the temperature, the load or both for the menu bar, and °C or °F.
-
Click the reading when the Mac feels hot. ⌘1, ⌘2 and ⌘3 switch between the HEAT, CPU and RAM boards.
Runs on
Apple Silicon Macs with macOS 14 or later. Intel Macs aren't supported yet.
Readings
Temperatures come from the same Apple Silicon sensor source Stats and iStat Menus use. A reading it can't get shows as unavailable, never a guess.
Distribution
Signed with a Developer ID and notarized by Apple, outside the Mac App Store, since the sandbox can't read sensor temperatures.
