If your Mac has a removable battery, skip this step and go to step 2.

Choose Apple menu > Shut Down.

After your Mac shuts down, press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button.

Release all keys. Press the power button again to turn on your Mac.
