No auto brightness on Thunderbolt Display (A1407)

[Jforte]

I bought a used Thunderbolt Display to Connect a MacBook Pro 15 2015.
My macbook has macOS Ventura 13.5 (with OCLP). I can adjust brightness, but i have no option regarding auto brightness.
the thunderbolt display is supposed to have an ambient light sensor and on “about this Mac”, under “adicional information- Graphics/monitors” i can see Thunderbolt Display information, and on “adjust brightness automatically” i can se “Yes”. I tried “lunar” and “monitor control”, but i cannot see the “auto brightness option” nowhere… do you guys know about a solution for this?

Wondering the same thing...searched for a solution...landed on your post.

I have found out that if I install the macOS Monterey (normal installation, since the MacBook model supports it) I have the auto brightness option. Looks like it is a OCLP "thing"...
