Smc Fan Control Mac Not Working iMac users who tweak their systems using 3rd party hard disks or solid state disks, are often surprised by an unpleasant aftermath: an annoyingly noisy hard disk fan. !!!You should execute this utility with root privileges!!!

This utility enables you to control your Mac's fans manually. So, this option is probably the most maintained option. Personally, I use the -SMC-enhanced option the most. Wait 5 seconds, then press the power button again to turn on your Mac. Plug the power cable back in, then turn on your Mac. Keep all four buttons pressed down for ten seconds, then let go. Hold the left Shift+Control+Option keys down, then press and hold the power button down. If that doesn’t resolve the issue, follow these steps: Choose Apple menu > Shut Down and wait for your Mac to shut down. Unplug the power, then shut down your Mac. You can cd build to check it out and use it. Press the power button again to turn on your Mac. The executable file is in the build folder.Xcode or Xcode command line tools should be installed.

Since I use this tool every day, I will continue to update it if I encounter bugs or I need more features. Therefore, support for other MacBook models is limited.

This tool is made only because I needed auto-fan-stop and manual fan speed control features on my 2018 15-inch MacBook Pro. So, a automation tool is needed and I created this tools. And if any monitored component tmperature reaches a certain threshold, I need the fans to turn back on. I need the fans to stop if everything is under control and the computer is idle. If I just stop the fans completely (which is made possible by this tool) and I forgot to turn it back on, the computer will overheat.

Due to the lack of auto-fan-stop feature, my 15-inch MacBook Pro is always taking in dust and debris even if the computer is idle, which results in the heatsink being blocked. That is to say, when the computer is idle, the fans automatically stops, like the fans on the 13-inch MacBook Pros do. Why I created this utility:Īs we all know, the recent 15-inch MacBook Pros do not have a auto-fan-stop feature. A nice little GUI and a icon will be placed on your menu bar (see here). You can use this tool with my-hammerspoon-config. You can edit the fan curve in the code yourself to make it work on other Macs (mainly fan speed limits).) Currently no support for other models is provided. (only applies to 15-inch MacBook Pros from 2016 to 2019 without the Vega graphics card. A small utility to control your MacBook's fans.
