WhateverGreen tiny Issue regarding Backlight Registers Fix

[schrup21]

Hi @ALL and sorry if you find my question wrong placed.

I got a really tiny issue with the Backlight Register Fix: I'm running 13.7 and 15.3 on the same machine and according WEG FAQs at 13.4 and up the alternate blr fix is needed (I'm using the DevicePropertie "enable-backlight-registers-alternative-fix").
Against the FAQs the alternate fix isn't working on my Ventura but on all above (14.0 and up) - indeed I need to activate the "previous" enable-backlight-registers-fix to prevent the 3 minutes blackout even in the latest version of Ventura.

This is a bit annoying because I can't load the right fix depending on the kernel version (at least I don't know of any way to do that). So all I can do is change the DeviceProperty before loading the other macOS (which I of course regularly forget to do).

My idea / question is: would it be possible to "move" the blr fix from DP to the WEG Kext, e.g. info.plist? Because a Kext of course I can load in dependence of the kernel version.

Btw.: the issue is the same when using boot-args.

I guess I got this, because my laptop has a whiskey lake cpu (i7-8565U) which aren't natively supported by macOS (correct me if I'm wrong - a whiskey lake Mac was never released). Btw. another even tinier #issue is a weird blinking, when the display switches from UEFI driver to iGPU...

So again: this is not a bug report, because everything works - just not as well as it could.

Please note this has been fixed by Apple in 13.5 and enable-backlight-registers-alternative-fix or -igfxblt is no longer required on macOS Ventura 13.5 and later

Thank you for your reply but I have to disagree.

If I deactivate the backlight register fixes, both OS (13.7.3 and 15.3) getting the "3 Minutes blackout". As I said above:

• on 13.7.3 I have to activate the Property enable-backlight-registers-fix, to prevent the issue
• on 14.0 and above (in the meantime I'm using 15.3) I have to activate enable-backlight-registers-alternative-fix
