Problem can be marked as solved. I preferred to go with the solution @Jake Lo provided. Now everything is working as expected.

Hi folks. I'm currently using @Jake Lo's Big Sur bootpack with modified SMBIOS to MacBookPro12,1 due to the Big Sur regression with older MacBookPro. My integrated webcam is not working now... (with Catalina it did) Is it because of the SMBIOS?

I can give you my "CLOVER" Folder... I generated new Serial Numbers for you. My 7440 is fully working. You just have to mount your EFI partition, remove/delete you clover folder, and replace it with mine. It would be nice to know some more of your system specs... WiFi, etc... CLOVER.zip

Hi. Which VoodooPS2 kext are you currently using? Never mind... You could try to replace your "ApplePS2Controller.kext" with the kext i attached for you. VoodooPS2Controller-R6Bronxteck.kext.zip

Hello forum members. In a german hackintosh forum i found some code snippet to correct map the brightness keys for a Latitude E7440. # _OSI(WIN7) is needed for brightness keys into method label OSID code_regex _OSI\s+\(WIN7\) replaceall_matched begin LOr(_OSI(WIN7),_OSI("Darwin")) end; #syscl_fixBrightnesskey_VoodooPS2 into method label BRT6 replace_content begin If (LEqual (Arg0, One))\n {\n Notify (LCD, 0x86)\n Notify (^^LPCB.PS2K, 0x0406)\n }\n If (And (Arg0, 0x02))\n {\n Notify (LCD, 0x87)\n Notify (^^LPCB.PS2K, 0x0405)\n }\n end; How and where do i have to implement this? And, is this compatible with the VoodooPS2 kext modified by @Bronxteck

Hi. Please provide full system specs, and a more detailed description of what you have tried so far. (e.g. what installer you tried, kexts, EFI folder.....) Thx. ... BUT ... i would not even recommend you to use that machine for a macHack... your dGPU (that RTX2070) has zero driver support for macOS ... so you would go with disabling it and using the iGPU (Intel UHD 630) of you CPU ... you will loose all the graphics power for what you paid so much, when you're running macOS instead of Windows or Linux.

@Hervé Yep, there is no dGPU built into that system. I'll try to disable "PluginType", and see what happens. EDIT: Another question... Is it necessary to inject the graphics card? Or ist ok to let Clover + WEG do the work automatically?

Hi there. After some weeks of using my "MacBook E5540" i think it's time to max out the performance of my system (mostly battery life)... Unfortunately i do not know how i can do this and succeed at 100% ... So, is there any person who may check my "debug" for stupid/bad/unnecessary configuration? I'm very interested in the "ACPI" part of my "config.plist" Thx in advance to everyone who is digging/crawling through config. debug_29750.zip

You have to enable "KernelPM" in Clover Configurator. I have added it for you. Just replace your "config.plist" with the attached "config.plist" inside your CLOVER folder. config.plist.zip

Well... so far i'm at the end of my knowledge... I now have no more ideas why your screen remains black after awaking from sleep...

Sad... Anyways... which config are you using in clover for booting your system, "config.plist" or "config 2.plist"?

@ftrela I guess, that i know your answer... but did you tried to adjust the backlight with somewhat like that "Fn + xx" shortcut?

Umm... i do not see the "SSDT-PNLF.aml" required for "AppleBacklightFixup.kext" in your "/CLOVER/ACPI/patched" folder... Try a fresh download from here. Put the kext into /C/K/other and the *.aml in /C/A/patched. Maybe this should finally solve your problem.

Could you post a actual debug ? There is only the one in the first post on this thread. Sorry... i've found the second one.

As i can see from your "kextcache_log.txt" you have that "IntelGraphicsFixup.kext" still in the kext-cache. Remove that KEXT from from /L/E and type/copy the following in terminal: sudo chmod -Rf 755 /S*/L*/E* sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo chown -Rf 0:0 /L*/E* sudo kextcache -i / Reboot and check if your problem is solved.
