shut down button gone, short cut?

Hi there, barbaraok!

Thanks for reaching out to the Apple Support Communities! That’s a great question you have about turning off your MacBook Pro. Check out this article for How to turn your Mac on or off. This article will give you the steps to locate the power button, depending on which MacBook Pro you have. The article will also provide you a link to an article with keyboard shortcuts to shut down your MacBook Pro.

Have a wonderful day!

The "booklet" is online in the form of various articles such as the ones linked to you. No booklet - less paper/money to print, I guess? Also, presuming you had a Mac before hand, the shut down button hasn't moved in macOS in at least a decade (in all the time I've had Macs). Always been there, same spot.

But, as for short cuts, here's a long list of short cuts you may find helpful in the future :) :

The shutdown button is still there.

My apologies, when I think 'button' I tend to think something you can click - not the physical key. Yeah, that looks different now. Sorry again!
