  2. Once it’s completely off, hold down Shift + Control + Option on the left side of the keyboard. As you’re holding them down, press the power button and hold them both for 10 seconds.
  3. Release the keys.
  4. Press the power button to turn your Mac on.

I did this a couple of days ago for my 2010 15″ MBP. It was working properly until I updated to High Sierra. When it went through the process, it failed. So, I asked @applesupport for assistance. To make a long story short, I did the SMC first. It did not work. Then I did NVRAM. Somewhat worked. I had to do a First Aid on my MBP per @applesupport. It turned out that my disk is shot.

Why does it take 3 pages for such a short and simple article ?

Is TMO taking to this style of publishing simply so it can show 3 sets of adverts ?

Would you rather pay for the article yourself? MacObserver has to make money to stay in business just like everybody else.
