Apple likes their computers quite so they leave the fans off for as long as possible. This could harmful if you are doing intense work or gaming in a hot location. I use SMC Fan Control to kick up the fans before the system get’s too hot.

Sadly SMC Fan Control stopped working after the High Sierra update, on my MacBook Pro 2013. If you have the same issue then try to reset the System Management Controller (SMC Reset).

Once you reset the Mac SMC, then the SMC Fan Control App should begin working again.

  1. When your Macbook is shut down hold Option + Command + P + R and the Power Button at the same time.
  2. Wait for the Mac to turn on, KEEP holding the buttons, you will hear the boot sound effect and it will reboot as you hold.
  3. Let go of the buttons after you hear the second boot sound.
  4. It should now turn on as normal

Hope it worked! My MacBook Pro is finally running cool again, is yours?
