I see a lot of questions on the internet on “how do I control monitor brightness on macOS?” and a lot of “just use Control+Brightness Up/Down” answers from people not realizing that only Apple vendored monitors support that. And that’s only possible because Apple implements a proprietary USB protocol inside their monitors for changing brightness so they have smooth transitions and be sure it works every time. I’m pretty sure they’ll never touch DDC/CI for that, and rightfully so as it has very spotty support, especially with these new Thunderbolt hubs/adapters and smart monitors. I’m glad Lunar works for you!

This was documented here: https://medium.com/@parttimeben/mac-it-just-works-horribly-c98fd9be4001 https://medium.com/@parttimeben/mac-it-just-works-horribly-c... I personally blame Apple for not supporting CEC. I have over 19 apps running in the background to “fix” macOS.

  I'm not an Apple fan, but I've tried to use CEC a bunch of times, and I can't blame them for not supporting it. It's not a good protocol.

    People end up using third party apps to do this anyway. That's actually less secure than if Apple did it.

    I don't know the protocol, but when it works it's really great as a end user.
