Benefits of Resetting SMC

Resetting SMC is one of the best options if you’re facing any issues with the MacBook. You can also reset SMC if your Mac says Wifi not configured.

You must be wondering what exactly the SMC does. Well, here’s an example. If you plug in the charger on your MacBook; the lights on the charger will turn on even if the device is completely shut down. This is what SMC does.

The other services SMC provides us are,

  • Respond while the power button is pressed.
  • Respond to the opening and closing of the Display Lid on the device.
  • Thermal and battery management.
  • Ambient light sensing.
  • Backlights of keyboards.
