Real chip temperature, no sudo
Reads the Apple Silicon sensors in-process through IOKit. No terminal commands, no admin password, no helper tool.
Brasa · Mac temperature monitor
BrasaKnow when your Mac is too hot.
Brasa is a light menu bar app for Apple Silicon Macs. It watches the chip, battery and SSD temperature, memory pressure, fans and the macOS thermal state, and tells you in plain words when to stop a heavy job.
Notarized download coming soon. For now, build it in one command (see the README).

01Features
A monitor that tells you what to do.
Numbers are easy to ignore. Brasa turns them into a state, a reason and a next step.
Four clear states
Safe, warming up, too hot, critical. The stone in the menu bar changes color, and the panel explains the risk and the next step.
Your limits, not ours
Defaults are 85, 92 and 100 °C for the chip. Change them in Settings; thresholds keep their order and each one resets to its default.
More than the chip
Battery and SSD temperature, memory pressure and swap, CPU and GPU load, fan speed, and the top processes heating the Mac.
Smart notifications
Alerts when the level changes and when it cools down, with a cool-down margin so it does not nag you at the edge of a limit.
Light and private
About 1% of one CPU core and ~55 MB of memory, read every 2 seconds. It makes no network requests and sends no data.
02How it works
Four levels, one stone.
The stone in the menu bar changes color with the state of your Mac. Open it for the reason and the numbers behind it.
Safe
Everything within normal range.
Warming up
Chip above 85 °C. Avoid starting a render or export.
Too hot
Chip above 92 °C. Pause heavy work until it drops below 80 °C.
Critical
Chip above 100 °C or macOS is throttling hard. Close what is heavy now.
03Limits
Your limits, not ours.
These are only the defaults. In Settings you change every threshold; they keep their order and each one can go back to its default.
85 / 92 / 100°CChip: warn, pause, critical
40 / 45°CBattery: warn, high
70 / 80°CSSD: warn, high
8GBSwap: warn
04FAQ
Quick answers.
Does Brasa need sudo or admin rights?
No. It reads the sensors directly from the app, so there is no password prompt and no privileged helper.
Which Macs does it support?
Apple Silicon Macs (M1 to M4) on macOS 14 or later. It is developed on a MacBook Pro with M4 Pro; sensor names can vary between chips, so reports from other models are welcome. Intel Macs are not supported.
Can it control my fans?
No. Brasa is a monitor: it shows fan speed and warns you, but it does not change fan curves.
Is it free and open source?
Yes. The source is on GitHub under the MIT license. If it helps you, you can support the project.
Does it collect data or use the internet?
No. Everything runs locally. The app makes no network requests and has no analytics.
How is it different from other Mac monitors?
Brasa focuses on safety: it turns temperatures into clear states with advice, keeps your own thresholds, and stays light. For full hardware dashboards or fan control, other tools are a better fit.
