The licence
- One purchase lets you use Puff on up to two Macs that you own or use.
- It's a one-time purchase. Updates to Puff 1.x are included.
- Puff is sold by Paddle.com, our reseller and merchant of record, who also handles customer service for orders and refunds.
What Puff does to your Mac
Puff changes the speed of your Mac's fans, only ever within the limits your Mac reports for them, and returns control to macOS when it quits, sleeps or stops. It installs a small background service that you approve in System Settings and can remove from Puff's Settings at any time.
No warranty
Puff is provided as it is. We work hard to make it safe and reliable, but we can't promise it will suit every Mac or never fail. To the extent the law allows, we aren't liable for indirect or consequential loss arising from its use.
