Tahoe 26.5 no longer lets you change the brightness of external monitors. 🥲
After upgrading to Tahoe 26.5, I can no longer change the brightness of my external monitor. The brightness control is always greyed out in the top menu and unavailable in the monitor settings, while the built-in display works fine.
Does anyone know how to fix this or report to apple? I am using betterdisplay app to control my external monitor’s brightness for now, but I would prefer a native solution if possible.
