Hi, thanks. I did it (again). Extrange is if i enter a value in config.plist->UEFI->Audio->Pciroot(0x0..... and my AudioCodec28, then in SystemPreferences (Finder) -> Output I get my internal Speakers shown. But no Bluetooh conections are possible. If I delete the Audio Device entry and codec in config list, then I get no internal speakers shown but I can connect to my external Bluetooth dongle! Suggestions??alc1.zip

Hi Mald0n, I have now a working USB dongle that works well but only if the internal USB is deactivated, which only happens when a choose another System Product Name in the Platform Info. This in turn deactivate the internal speakers of the laptop, so i can only use the Bluetooth way That's why I would like to ask you to deactivate the internal Bluetooth in my DSDT.aml. Would you please do that for me (SendMe attached)? Send me emilis-MacBook-Pro.zip

UPDATE: I performed an installation from the scratch and I must say it works much better though not so fluid as under Catalina. Extrange too that when deleting VRAM the boot path on the SSDg gets lost and I must enter it again(!) Another thing: Can you recommend a Bluetooth USB dongle/stick that works well under BigSur?

Hold in. I'll perform a new installation. May its then gone.

windows, mouse and keyboard work or move slow. Colors may be wrong and fonts may disappear because turning from black to white. Somehow better with OC 6.4 but not satisfying. The effect does not appear under Clover. Take a look at the screenshot.

Here you go. Send me MacBook-Pro.81220.zip

Thanks. I can boot now from the SSD. Extrange. What can I do to accelerate the graphics? They are really, really slow.

In the past for clover you had to define the path in the Bios : something like efi/clover/cloverx64.efi. Is there anything similar for OC? I don’t understand it myself neither but just copying doesn’t work! Any idea what can it be? Anything wrong with the boot sectors of the SSD?

Sure. That’s what I do. But it won’t be found. The Computer insists in using only the USB.

Incredible! ??. Now How do I boot from the SSD. Just copying the EFI folder to the efi partition doesn’t do!?

Not quite understood. Can you be more explicit? Is t all just a matter of choosing the right smbios?

For several daydnalready trying to install BigSur (latest Olarila image on latest Opencore and Clover ) on my IvyBridge Asus Laptop (Intel(R) Core(TM) i7-3610QM CPU @ 2.30GHz). Lately I got pretty far and after several new starts when it seems the installation is done and I should boot from the recent installed disk I get the error above. Needles to say I tried several Bios descriptions but no luck.config.plist.zip . Any suggestions?

Thanks but since I get a kernel panic if I install in the Opencore kext folder should I install under System/Library/Extensions? and if so how? I cant change the system and the kext Utility does not help neither...

Anything regardind Bluetooth?

Thanks. The USB ports appear to work well now (though I dont habe USBports.kext but USBinjektall.kext. Bluetooth does not yet. Any idea? Muito obrigado pela sua ajuda?

Send me141120.zip Bluetooth again down despite new NVRAM (no I do not want to go crazy!!!). The graphics are generally still unstable (breaking windows) and slow.

UPDATE: Bluetooth seems to work now. Still: USB problem

Appears to be Intel. Ins'nt it? Look at the attached file.pcidevices.txt.zip

The build-in one appears to be Atheros Communications. I never got it working, neither under clover. So bought a stick-in one. This second one works well under clover and mostly (!?) under OpenCore. This one is a 0x0A12 Cambridge Silicon Radio Ltd. I do not really know how to check if usb3 is intel or not. IOregistry shows only the device attached but not the USB vendor. Or am I wrong? Atheros.zip CASiRa.zip

Thanks done. Bluetooth and USB still not willing...

Send me131120.zip Thanks.

Tried 3times with XhciPortLimit checked inthe config.plist and XHCI-unsupported.kext, USBInjectAll.kext. Removed all in Hackintool and connected all USB Ports first with a USB2 dongle and then with a USB3. But nothig happens on the one side of my laptop : no light gehts on or appearance on the desktop. Only on one side. Of course I cleaned the VRAM everytime. Extrange. The graphics is slow. Probably w/o acceleration. And should I keep Nullcpupowermanagement in the kext folder? Am I missing anything?

I know. Sorry. Didn't mean so. But I was unsure, because the config.list check said to NOT put dsdt,aml under OC/ACPI. And I try to save you as much as possible from asking you stupid questions ☹️.

Hi Mald0n, thought Dortania's instructions warns no to put any dsdt under OC/ACPI I think that's the place where you want me to try it.So I did and it works pretty well. The biggest issue thougt is the USB port problem, as only half of the ports work. Can you have a look at this? Thanks
