Any suggestions for users to file a radar with Apple for this feature? For now, QuickShade is not a bad alternative. Looking forward to seeing if you get access to the controls on the M1. Yes, Apple vendored displays might still work as there is an alternative method implemented in Lunar that doesn't use DDC. I purchased a thunderbolt 2 display from a decade ago, that works nicely and has brightness control on the M1 - does need a thunderbolt 2 to usb-c adapter though 😂
