Apple diagnostics

I've got a new Mac that has unexpectedly restarted a few times. I've tried to run diagnostics but can't get then to run.

Online it says to restart hold the 'd' key down and this will start the diagnostics. I'm taken to a screen that has a listing of languages and then two options at the bottom; restart/shutdoen.

If I use 'option-d' I getting a spiny globe with a message about internet recovery.

So how do I kick this off?

Rather do this:

Restart and as it chimes, hold down Command + S

Black screen and text runs down the screen.

When it stops type : fsck -fy and hit Enter/Return.

A diagnostic starts running for a few minutes. By the end it might say: System has been modified. If so, run fsck -fy again

If the second time  (or the first time) it does not say System has been modified, then type in: reboot.

If there are major faults going on you will probably get some text about it. You should then take the mac to the seller and talk it over with him.
If it is less than a year old it is still under warranty. Take it in to the Genius Bar at an Apple Store.

I just want to know how to run the diagnostics. I don't want to haul it to the genius bar.

Otherwise I would have posted a question 'How do I get to the genius bar?'

Restarting hiding down the d key is supposed to start the diagnostics. If it doesn't, you have a problem.
