When should I reset my SMC?
Resetting the System Management Controller (SMC) on your Mac can be a helpful troubleshooting step in various situations. Here are some instances where you might consider performing an SMC reset:
1. Fans running at high speed and making excessive noise: If your computer’s fans are constantly speeding up and creating a lot of noise, it could indicate a problem with the SMC. Resetting it can help resolve any issues related to fan control and prevent your Mac from overheating.
2. Keyboard backlight not working correctly: Sometimes, the backlight on your Mac’s keyboard may not function as expected. This can be due to a glitch in the SMC. Resetting it might fix the problem and restore proper functioning of the keyboard backlight.
3. Power-related issues: If your Mac is experiencing power-related problems, such as not turning on or not charging properly, an SMC reset might help. It can reset the power management settings and potentially resolve any issues related to power delivery.
4. System performance issues: In some cases, your Mac may start to exhibit sluggish performance or unexpected freezes. These issues can sometimes be attributed to SMC-related problems. Resetting the SMC can help refresh the system’s power management and potentially improve overall performance.
Now, let’s discuss how you can perform an SMC reset based on the type of Mac you have:
– Mac Laptop That Does Not Have a Removable Battery:
1. Shut down your Mac completely.
2. Connect your Mac to a power source.
3. Press and hold the Shift + Control + Option keys on the left side of the keyboard.
4. While holding these keys, press and hold the power button for about 10 seconds.
5. Release all the keys and power button.
6. Press the power button again to turn on your Mac.

Personal experience: I have reset the SMC on my own Macbook Pro when I noticed the fans running at high speed even when the system was not under heavy load. After performing the SMC reset, the fan noise reduced significantly, and the temperature of my Macbook returned to normal levels.
