Free macOS tool

tempfandock

A tiny native widget that shows your Mac's CPU and GPU temperature and fan RPM at a glance – read straight from the SMC, with live gauges and a rolling history. It floats quietly on your desktop, no Dock clutter.

  • Native macOS – PyObjC / Cocoa
  • Reads SMC sensors via IOKit, no kernel extension
  • Always-on-top, accessory window, no Dock icon
  • Signed and notarized by Apple

v1.0.0 – Intel Macs – macOS 13 Ventura or later – free.
