Reset SMC MacBook Pro

If your MacBook starts acting up, you should probably run through some standard troubleshooting procedures. Some of these include restarting it and running Disk Utility as well as doing a Safe Boot.

You can also try zapping the NVRAM if none of those work to eliminate otherwise inscrutable problems in this case! In this article, we will go over how to reset SMC MacBook Pro

What is the System Management Controller (SMC)?

The System Management Controller (SMC) is an essential component of your Mac that assists in power management, temperature monitoring, and fan control.

Problems with the SMC can lead to many issues, including excessive loud noise coming from fans or slow performance even though Activity Monitor doesn’t show CPU being overtaxed.

What Does the SMC Manage?

The SMC is responsible for managing behaviors related to these features:

  • Power, including the power button and power to the USB ports
  • Battery and charging
  • Fans and thermal-management features
  • Indicators such as sleep status, battery charging status, and others
  • Sensors such as the ambient light sensor, keyboard backlighting and, sudden motion sensor
  • Behavior when opening and closing the lid of a notebook computer

Apple states that you should first try other troubleshooting tasks, like force-quitting problematic apps and restarting your Mac before resetting the SMC.

However, they don’t specify any adverse consequences of doing so. I’ve done this many times with no apparent adverse effects, and on occasion, my problems were resolved by performing these steps as well!
