I built MacGlow - A MacOS app to sync brightness across your Mac and all connected Monitors.

Supports every Macbook Air, Pro, iMac and Mac Mini models ever released running MacOS 12.4 and above.

Nice demo. Seems useful.

Thanks

It would actually be super useful if this could be extended to work with Universal Control. I have a 24in iMac and a MacBook Pro. Being able to sync the brightness across devices would be great.

Interesting thought, thanks for your input. I will look into it and add this feature. Just to clarify, you would like to control the brightness of your iMac from Macbook Pro and vice versa from the MacGlow app. Did I understand it right?
