How to Reset SMC on MacBook Pro – A Guide by My Blog

Are you dealing with unusual or frustrating issues on your MacBook Pro? Is it acting up in ways that are driving you crazy? Don’t worry, there might be a solution to your problems. Resetting the System Management Controller (SMC) on your MacBook Pro can help resolve issues related to power, battery, and other core functions of your device. In this article, we will guide you through the steps to reset the SMC on your MacBook Pro and provide tips on when it may be necessary to do so.

Understanding SMC and Its Role

Before we dive into the process of resetting the SMC, let’s first understand what it is and the role it plays in your MacBook Pro. The SMC is a chip on the motherboard that controls various hardware components, power management, and system-level functions. It is responsible for managing fan speed, battery and power management, keyboard backlighting, ambient light sensing, display backlighting, and more. Basically, the SMC ensures the smooth functioning of your MacBook Pro, and resetting it can help resolve issues related to its hardware components and system-level functions.

When to Reset SMC

If you’re experiencing any of the following issues, it may be a good idea to reset the SMC:

  • Overheating
  • Abnormally high CPU usage
  • Poor battery performance
  • Charging problems
  • Sudden motion sensor not working
  • Keyboard backlighting issues
  • Status indicator lights not working
  • Trouble using Target Display Mode
  • Power management settings not working correctly
  • Ambient lighting sensor not working correctly

However, before resetting the SMC, it’s important to troubleshoot the problem to ensure that it is the right solution. For example, if your MacBook Pro is overheating, check for applications that may be using a lot of CPU resources and close them. If your battery performance is poor, adjust settings to improve battery life. Resetting the SMC should be your next step after you’ve tried troubleshooting.

How to Reset SMC on MacBook Pro

If your MacBook Pro is experiencing power-related issues, here’s how you can reset the SMC:

  1. Shut down your MacBook Pro by clicking the Apple icon in the top-right corner and selecting Shut Down.
  2. Press and hold the power button on your MacBook Pro for 10 seconds before releasing it.
  3. Wait a few seconds and then press the power button again to turn your MacBook Pro back on.

Note: If you have a MacBook Pro with Touch ID, press and hold the Touch ID button instead of the power button in step 2.

If resetting the SMC doesn’t resolve your issue, you can try resetting the NVRAM/PRAM by holding down the Option, Command, P, and R keys while powering on your MacBook Pro.

For MacBook Pro models with a T2 security chip, the process is slightly different:

  1. Shut down your MacBook Pro.
  2. Press and hold the power button for 10 seconds.
  3. Release the power button and then press and hold the Option, Shift, and Control keys for 7 seconds.
  4. While still holding those keys, press and hold the power button for another 7 seconds.
  5. Release all of the keys and wait a few seconds before turning your MacBook Pro back on.

That’s it! Resetting the SMC on your MacBook Pro should help resolve any power-related issues you may be experiencing.
