MacBook started card? Reset SMC can help you

Many small partners complain that Macs have slowed down over time, mostly due to hardware degradation or failure to keep up with the latest systems, and sometimes software problems.

One simple trick is to reset the MacBook's System Management Controller (SMC). SMC controls low-level features based on Intel's MacBook, such as battery management, thermal management, and pressing the power button. Although it may seem irrelevant, resetting the SMC on a slow-performing MacBook may also make it run like a new one again.

One, 12-inch MacBook and early MacBook Air

1. Press and hold the shutdown button and wait until the Mac is completely powered off.

2. Hold down the Shift-Command-Option three buttons on the left side of the keyboard, then press and hold the power button for 10 seconds.

3, release all the buttons

4. Press the power button again to restart the MacBook.

Second, the 2018 MacBook Air and MacBook Pro
