Master your Mac's
thermals.
A native menu bar app to monitor temperatures and control fan speeds in real-time. Works on Apple Silicon & Intel Macs.
What's new in v1.3.0
- Settings Window — standalone macOS settings window with liquid glass UI.
- Status Bar Display Modes — choose None, Temperature, Power Usage (Watts) or Fan Speed %; Power now shows Watts when available.
- Stability fixes — SMC parsing fixes prevent crashes and improve robustness.
