How do I reset my Mac, MacBook, MacBook Pro, etc?

There are a couple of steps to reset some of the underlying power controllers and firmware on a Mac Computer. This has become even more important to know now that batteries are internal and non-removable.

  2. On your built-in keyboard, press and hold all of these keys:
    • Shift  on the left side of your keyboard
    • Control  on the left side of your keyboard
    • Option (Alt)  on the left side of your keyboard
  3. While holding all three keys, press and hold the power button as well
  4. Keep holding all four keys for 10 seconds.
  5. Release all keys, then press the power button to turn on your Mac.
