As long as your default mode is sleep it'd be ok. I touch my PCs power button only when it crashes so horribly that a forced shutdown is the only way out...

Unless your computer has issues, can’t you just power off from within macOS?

On the bottom, in the back...

Hahaha I thought this was the onion and the button was the big fugly thing that covers the whole bottom

I really hope this is one of those tactile hit it from the top and it'll trigger from the bottom designs. But more likely they just never expect you to use it.

This is more like a "power button" in that case lol
