Use only external Monitor on MacBook Pro When in my office, I want to disable the internal display of my 16" MBP 2019 since it's disturbing and uses extra resources.

The Windows solution would be pretty simple: WIN + P > external display only

I cannot figure out how to do the same on MacOS

Not a fix is


Just turning down the brightness


it keeps turning back on
the monitor is still used and everything is rendered on two resolutions
even though it's very dark, you can still see the contents

Closing the lid


I want to be able to use trackpad, touch-id, keyboard, touchbar

Using a magnet


couldn't figure where to place the magnets



I already wasted hours trying to find a solution and it seems to be such a trivial problem to solve ...
At the risk of being publicly wrong, this isn't something that's easy. macOS just wants you to close the clamshell to put off the screen. I understand you understand and reject this solution, but it's the only practical one we know of today.

I believe that people that used to do that at work with space for two large displays now may work from home and we'll see lots of changes as a result of common pain points, but there will need to be a change in the operating system to make this easy.

The closest you could get is using bluetooth / usb keyboard and trackpad but you'll lose the physical trackpad / physical Touch ID and the task bar when you close the lid.
