the iMac screen is internal and doesn't use DDC, so ddcctl
doesn't support it.
Same for MacBook screens.
I guess you need to use both tools? I know that sounds weird, but they both are using two very different and finnicky APIs that Apple semi-supports.
I'm excited to see an active project dealing with command line controls for displays on macOS. I use https://github.com/nriley/brightness to retrieve & set brightness in a lab of iMacs (Retina 5K, 27-inch, 2017). While this tool works well on my Mac Pro (5,1) with two Apple Cinema Displays, when run on one of the iMacs I get: I: found 0 external display
Just wondering if there are shortcomings with iMacs displays that would prevent this tool ever working?
