How to close MacBook and Use Monitor (Clamshell Mode)

I think there is a way for me to connect a monitor to my MacBook, then shut the MacBook and use the monitor on its own. I believe it's called Clamshell Mode for your Mac, but I don't know how to do it.

So the mode:

Clamshell mode (Lid Closed)

for MacBooks [Intel or Arm] is entered automatically, if you have connected:

[1]-keyboard, [2]-mouse, [3]-display... and [4]-power...

And also, there is NOT any specific setting for this...

All correct?

My caveat about clamshell mode is heat. Some Macbook Pros draw cooling air in through the keyboard. In this article:

Apple says, "Don’t put anything over the keyboard." 



To me, closing the display puts something over the keyboard!


If your Macbook Pro has side vents, this is less of a problem. However, not all Macbook Pros have side vents.



Another common mistake that people make when using clamshell mode is to put the closed computer vertically like a book on the workstation to get it out of the way.


Therein lies the problem. If you place it vertically with the hinge down, YOU BLOCK THE CRITICAL EXHAUST VENTING! High heat can cause premature failures.


If you must do this, place the computer with its hinge UP.
