Native XDR Brightness Upscaling in 26.3

[waydabber]

Please note that the Native XDR Upscaling feature does not work in macOS Tahoe 26.3 beta with the current stable (v4.1.1) version.

UPDATE: Apple actively prevents this feature from working in macOS Tahoe 26.3 beta3. This seems to be an intentional limitation going forward. No more workarounds expected.

Of course the standard (software) upscaling continues to work and it's a great option for most users.

Those who depend heavily on native XDR upscaling should avoid upgrading to 26.3.

Tested in M4 Pro - Problems above 30% brightness :)

Yes, indeed. I'll check to see what can be done about it. Let's track this further under #4929.

Yes , 26.3 Beta 3 . totally broke.

Right. Those who depend heavily on native XDR upscaling should avoid upgrading to 26.3.

I'll remove this feature going forward for 26.3+ installations. The message is clear from Apple, they don't want this anymore. The technique this uses might interfere with some future products (new displays or the OLED MBP maybe? - not sure). I am sure they have good reasons.

Ohh this is sooo bad! I installed macOS 26.3 today and was so disappointed that the native upscaling isn't working!! This one was one of the reasons I was so excited when I got my M3 Max MacBook Pro and Better Display maybe the first app I installed on it, and you're telling me that now it can't work?! Just with a f*ckin update?!
Isn't any hope you'll find a workaround? I mean, this is very serious...
