I'm unable to reproduce this, you're certain that the external monitor was "focussed" here? Because there's currently a bug where the external monitor will not be controlled if internal is "active/foccused" (when you click in it).

I've spotted this issue - only affecting the brightness keys, via the icon it still works - but I didn't need terminal to be in focus.

Seemed to me to be that when Terminal is running (but does not necessarily have an open window) and Secure Keyboard Entry is enabled in Terminal, then brightness keys only affect built in Mac monitors.

Turn off Secure Keyboard Entry and it works again, so I assume it's caused by the fact Secure Keyboard Entry is meant to prevent key loggers etc and so MonitorControl is unable to receive the key presses?

@clheppell That makes a lot of sense, I'll try it out to confirm when I get time 😃

I just tested and Security Keyboard Entry was it!

Thanks
