Hello everyone I solved the problem to enable audio in Big Sur with Opencore, thanks to my friend gengik84 for solving the problem by applying DSDT activation of my motherboard .. Another mystery that has not been solved with opencore because using the "alcid" procedure it does not detect the audio card, while with Clover it does not happen .. Now it works in Fullprofilo Big Sur.

There you go, I removed my personal data (PlatformInfo) EFI.zip

Mine was already compiled after compiling OpenCore in the /OpenCorePkg/Utilities/ocvalidate/ folder.

I'm on a ryzen system mate.

No! Use OC utility ocvalidate.

Samsung Pro 950 should be OK right? I think its more related to some kext or boot args, maybe I'm wrong I don't know

Please share your EFI bro!

Open a terminal git clone https://github.com/acidanthera/OpenCorePkg.git Go to Opencore directory just create after "git clone" launch ./build_oc.tool Build results will be in subdirectory UDK/Build/OpenCorePkg/ -> DEBUG,NOOPT,RELEASE Unzip OpenCore-0.6.0-xxxx.zip according to your choice. Result will be in OpenCore-0.6.0-xxxx/Utilities/ocvalidate Fred

Doesn't matter as you booted to macOS.

I'm not Big Sur but, OK.. fine. BigSur-Sunset-Retouched-1080.jpg.zip

Not for my hack, I'll investigate when be back from vacations. Fred

I think the problem with BigSur installation is in procedure InjectKexts(...) which are developed years ago. It worked when prelinkedkernel is used . But probably it is not working when we install bigsur with KernelCollection file. Where to get such information? OpenCore is successful because it used other method to inject kexts.

Just use that app to generate a 0.5.9 config and then use OCBuilder app to compile 0.6.0 and update the config.plist with the changes from the Sample.plist.

Slightly off-topic, but as many folks are asking about dual boot. TL;DR: Yes, just don't patch ACPI.

FYI, I just compiled Opencore and now my boot drive is indeed macOS and no preboot anymore.

Good Old Day! Just installed latest macOS Catalina 10.15.6 on Toshiba Satellite L640 with Intel HD 1st Gen (Arrandale): 1. Using dosdude's Catalina Patcher app for creating Bootable USB Installer plus Post Install (rolling back deprecated Graphics kexts, OpenGL frameworks, Platform patch, etc) for unsupported mach << needs 2 x USB Boots for OS Install and then Post-Install 2. config.plist - Devices - FakeID - IntelGfx=0x12345678 for Pre-Install 3. To achieve QE/CI or Graphics Acceleration with WEG (+Lilu) installed, add Properties for Graphics on config.plist - Devices (plz refer to the manual, or see my screenshot & sample below. Thanks to GoldFish64). Remove IntelGfx FakeID on this case 4. For Native (ACPI) Brightness to works, patched DSDT is needed following old mnorthern's guide. Take a look attached DSDT below. For reference, find: LEVL, os-info, LGD018B, PNLF, _WAK. Also, replace DisplayServices.framework from 10.12.4 located on /System/Library/PrivateFrameworks/ and add Rehabman's IntelBacklight.kext v1.0.12 (attached) to \EFI\CLOVER\kexts\Other. On my case, Display Brightness Slider is working (or Fn + Keys if remapped already) with no longer need BergDesign incompat 32-bit app. If you have better idea, then let me know. #SomeHINTS: - Platform patch is needed when using unsupported SMBios (eg. MBP6,x) under Catalina. For me, simply change to MBP10,1 BUT.. hey, there will be few issues with PowerManagement, USB Ports, etc (though I've manually fixed them via ACPI) so.., DWYOR! - Use only one PNLF method, choose between Clover Patch, or ACPI (DSDT / SSDT) - Graphics glitch on some apps is known issue with Legacy OpenGL / Metal incapable Graphics under Catalina (and Mojave), but thanks to @AsentientBot for bringing QE/CI back to unsupported mach anyway (Oops, I have no idea with BigSur, my Beta1 download has not finished yet once later Beta was seeded #LOL) Good luck! config_devices_properties.plist.zip DSDT_Sample_Only.aml.zip DisplayServices.framework_10.12.4.zip IntelBacklight.kext_v1.0.12.zip

Hey @pkdesign. I use the icnspack utility from OpenCore. It takes a 128x128px and 256x256px PNG file, and writes them to a new file with the correct icns headers.

Write here as remind for myself. Since C++ I have only daylight theme (?). 2:964 0:000 === [ InitXTheme ] ============================== 2:964 0:000 use Daylight theme While Clover-5098 makes me Night.

Why ? Works better than open core, why emulate a mac on PC to boot windows? Just run it natively on the hardware. I had open core booting windows, right up to the point where I had to re-install windows. Now I just use the bios, not like I'm doing it everyday.

creepy ...
