I want to be able to use a macbook with external display with closed lid, but it cannot do that. As soon as I close the lid, there's no signal to the display and no amount of keystrokes on external keyboard or mouse can change that.
A few things which I tried (all totally useless):
caffeinaterunning in background
- disabling sleep:
sudo pmset -b sleep 0; sudo pmset -b disablesleep 1
Display is connected via HDMI.
Macos version = 10.13.6.
AC adapter is plugged in.
