MacBooks are high-end computers that generally “just work.” However, over time, users might begin to notice their laptop starting to slow down, function oddly, or maybe exhibit battery drainage.

Luckily, there’s a simple trick (most MacBook users have never tried) that can fix all of these issues in just one go. All they have to do is reset their MacBook’s System Management Controller (SMC).

The SMC controls low-level functions on Intel-based MacBooks like battery management, thermal management, presses of the power button and more. While it seems unrelated, resetting the SMC on a slow performing MacBook (even with low CPU-utilization), could make it run like new again. Here’s how to do it.

How to Reset a MacBook’s System Management Controller (SMC)

These are instructions for MacBook models without a removable battery and without Apple’s T2 chip, like the 12″ MacBook and early MacBook Air models. T2 chips are found in new MacBook Air models (introduced in 2018) as well as MacBook Pro models (introduced in 2018). For instructions related to those devices, skip toward the bottom of this page.
