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. |

UPDATE: Apple actively prevented 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. |

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?! |

I see that you managed to fix native xdr , however im unable to update to pre-release even after checking that box. |

What fix are you talking about? |

Sorry, this is probably a misunderstanding. There was a pre-release that fixed the native XDR upscaling in 26.3 beta1 and 2, but then Apple decided to counter that (or make further changes due to unrelated reasons, who knows...). So right now native upscaling is not available, macOS will remove any preset that is out of bounds and this protection cannot is something we have no way of overcoming (in a reasonable way that is suitable for an app geared for normal users). |

It would be nice if you provided a SIP off version that would tweak the frameworks needed to be tweaked so it could work again, for more advanced users who want to do the extra step. |

I second this! I disabled SIP (or parts of it can't remember) in order to disable a bunch of unwanted system frameworks. If you could still provide the native XDR brightness upscaling when SIP is disabled, please do! |

The thing is, if I'm not mistaken, that even if he eventually find a way to disable the preset validations on ProDisplayLibrary.framework and/or other frameworks and make native XDR upscaling work again, because this will happen by modifying those frameworks that are inside the dyld cache file, which is signed by Apple if I'm not mistaken, every macOS update would brake it and the patch will have to be applied again. Personally, if that's the only way to have back this amazing feature that truly upgrades my MacBook, and if the way to patch it after every update isn't that hard, I totally accept the trade off! |

Has this been solved ? |

So you mean that you found another way to increase brightness apart from the HDR overlay we currently have with the software XDR upscaling, and that workaround works on your M3 MacBook Pro? Does this affect actual HDR content like the overlay does? |

Yes, this is a different approach, not used by the app yet (or any other app afaik). However it works best when the display is not on EDR mode, so if I implemented this I'd activate a preset that disables EDR altogether. Anyway, this is not something I am working on right now, I just did some superficial testing and seems to work fine. But I think I'll then introduce a terminal-only command to enable this in an upcoming version so it flies under the radar but can be useful for those who really need it for any reason + to gather some feedback. (note: just a minor correction, software upscaling - using color table - does not use a full screen HDR overlay, but must switch the display into EDR mode - the only standard way is to have some - even invisible - HDR content on screen). |

Looking forward to that update man! |

@Simos805 I agree completely. There really should be an ambient light sensor on the BACK of the display, not the front, because that's what our eyes are seeing! I constantly need to work in an environment where I'm right in front of a bright window, and so I need the high brightness, even more so than the 1000 nits that a newer Macbook would allow stock. @waydabber If you have found another way to implement native brightness upscaling that behaves the same way it did before (not messing up HDR content), please let us test it! |

Ironically, the new Studio Display XDR (which I ordered yesterday!) has ambient light sensors both front and back! |

I can't seem to make even software brightness upscaling work on the built-in display of my my M4 Macbook Pro (14”); BetterDisplay seems to falsely think the built-in display doesn’t support HDR, and tap out at 100%?

Something seems to be off indeed. The "Supports HDR - No" is fine for the XDR display (this is reported as Yes for HDR capable third party external displays), as the EDR range seems to indicate that the display is otherwise EDR compatible (so it can show HDR content). But it is weird that Apple Display Presets are reported as unsupported. Did this ever work? Which app version are you using and what preset is configured for the display? |

this issue was observed on the most recent app version (Version 4.2.2 Build 48115) but after updating to the later 26.4 beta (beta 4) and restarting my laptop it seems to be detecting correctly; idk if it was a beta issue or just needed the restart? it has worked in the past too, yeah

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.

The following info is now outdated and does not work since 26.3 beta3:
You need to upgrade to the latest pre-release version (enable Settings > Application > Updates > Receive pre-release updates and then do a Check for Updates).
The release is available here to download:
https://github.com/waydabber/BetterDisplay/releases
Configure the XDR upscaling feature here:
