  1. Shut down the Mac and connect it to your MagSafe adapter and a wall outlet as usual
  2. Hold down the Shift+Control+Option+Power button at the same time for a few seconds
  3. Release all keys at the same time, then boot the Mac as usual

Do you still have the issue?

  1. Press the Power / OFF button once – this will bring up the dialog box which you can’t see
  2. Press the “S” button – this is the shortcut to sleep the Mac
  3. Hold down the Power button until a hard shut down is forced
  4. Wait about 15 seconds, then hit the Power button again to turn it back on
Customer: replied 1 month ago.
Do I keep holding the s down during the hard shut down?
Expert:  Josh replied 1 month ago.

No, you will only press the "S" key

Customer: replied 1 month ago.
