Frequently asked
Can Airflow harm my Mac?
No. Fans never go below the lowest speed the hardware allows, and macOS keeps running its own thermal protections. If a sensor stops reporting, the fan curve fails safe to full speed.
What happens when I quit?
You choose in Settings. By default, fans go back to macOS's automatic control.
Why does it ask to install a helper?
Changing fan speed needs admin rights. The helper is installed once, after you approve it in System Settings, and only passes fan commands along.
Which Macs does it support?
Apple silicon Macs with fans, running macOS 14 Sonoma or later. On fanless models (like MacBook Air) it shows temperatures only.
Does it collect any data?
No. Airflow has no analytics, no accounts and makes no network requests. Everything stays on your Mac.
Is it free?
Yes. Airflow is free and open source under the MIT license. The code is on GitHub.
Stay cool. Work quiet.
Setup takes a minute, and you can hand your fans back to macOS any time.
