I use my Mac a lot to show movies or play video games on a larger display without a keyboard or mouse attached.
How can I set up my Mac so that it continues to display to an external screen when closed without a keyboard or mouse attached?

There’s no easy way to avoid closed clamshell. Why not connect a mouse to get your functionality? – bmike Feb 09 '20 at 21:21

@bmike When going from place to place such as campus screens or a friends house, it doesn’t make sense for me to carry around an entire keyboard and mouse at all times. – Libra Feb 10 '20 at 00:47

You’re using the wrong tool for the job. Since this functionality is outside of macOS and part of the hardware, you have two choices: use a travel mouse as it’s small and cheap, or get a Mac mini. – Allan Feb 10 '20 at 14:52

@Allan There is definitely a way to do this, there always is. I understand now though that there is definitely no native way to do it – Libra Feb 10 '20 at 15:20

I would connect a Bluetooth keyboard and mouse if you can’t have physical cables connected.
This function is in firmware, so you’d need to engineer a solution to change Apple’s conditions for closed clamshell mode.

Bluetooth mouse and keyboard are still physical haha. I am open to third party software – Libra Feb 10 '20 at 00:43
