New Update OC 0.6.7 macOS 11.2.3 Prerequisites: *Nvram and MsrsE2 patched BIOS. If no MsrsE2 is patched then set AppleCpuPmCfgLock and AppleXcpmCfgLock Booleans to TRUE in Kernel\Quirks. *Generate your own SMBIOS. The whole process took 7 minutes and 3 reboots. Good luck.

Hi. Post install can vary a lot from one system to other. My first step will be to map usb ports. checking if you actually have an unlocked Msrs. You can use the check tool on picker. Double check the dortania opencore guide looking for little things you may have missed.

Hi again, I did some edits to your SSDT-RTC0-RANGE.aml RTC name is RTC LowPinCount path is LPC0 PCI path is PCI1 This is the V1 EFI with Write Flash set to false. If it fails try enabling it. Hope this helps. Please also check your BIOS settings. Disable Fast Boot Secure Boot Serial/COM...

Hi again. Please try this 2 EFI folders. They are as clean possible. The difference between them is that V2 has Flash Write enabled. If none of them work for you, please dump your DSDT and post it here. It could be that your motherboard version needs some SSDT edits. Good luck

Hi. Try this one as it is.

Hi. Today I successfully Updated to OpenCore 0.6.6 and flawlessly updated to MacOS 11.2.1. My specs: Asus X99-A Intel I 7 5820K 4x 4GB ddr4 3200 Asus Radeon Vega 56 BIOS Asus X99-A Version 4101 with patched Msrs and Nvram (Attached below)

Hi every one. Today I successfully updated my hackintosh to OpenCore 0.6.6. My EFI folder works perfectly fine with Catalina and also with Big Sur. Please note that my Mother board is an Asus X99-A (no X99A-ii, deluxe, WS, etc) And my CPU is an Intel I7 5820k.

Maybe you typed it wrong the first time during setup. It can happen that the keyboard layout varies from setup to working system. Try inserting the same password with different typos. Also check that your keyboard is set properly for your language.

Hi Opencore is frequently updated and focuses on security. and now easy steps to install catalina with opencore. 1 create your catalina usb installer. 2 mount the EFI partition using EFI mount. 3 copy my uncompressed EFI folder to your usb installer. 4 boot from usb. 5 choose install catalina...

You basically have my same machine except for the video card which is a Kepler GK106 (Not fully supported I guess). I am using OpenCore not clover. You can take my EFI folder as it is, and that should make most of the work, but if it fails you are going to need a different Video card. Please...

Try this flags: -v -no_compat_check npci=0x2000

You can try this EFI. When you first boot with it, Use the CleanNVRam tool. Then, start installing Or upgrading Good luck.

Works perfectly fine also with catalina. And sadly the only way to know if the bios is well patched, (at least for us mortals) is to flash it and hope the motherboard boots. Or learn from Win-Raid forum how to mod a bios like a pro.

Hi hellowe. Yes of course. The first and most important thing should be patching the bios to unlock nvram whitelist.This can be done with uefipatch (not recommended) or manually. Sadly manual patching of the bios is really hard for newbies, me included. I first did it with uefipatch and later on...

Success Flashed a patched bios for X99-a provided by Win-Raid forum user dragonsun252 and your EFI folder edited for my machine Thank you very much.

Hi every one. I finally manage to install Big Sur on this machine. It took a lot of time. The help of tonymacx86 @jin.artemis which gave me his EFI folder and @dragonsun252 from Win-Raid Forum which provided me with an nvram patched bios for my motherboard X99-a. (WARNING- DANGEROUS STUFF...

So. today I mange to patch and flash my X99A 4101 bios. Complete of microcode, MSR 0xE2 register and Native NVRAM whitelist. And again I still rebooting on stage 2. This thing is driving me nuts. I suspect it can be something with my EFI. Would you mind share your EFI folder? I attach my...

I found very impressive that you manage to install Big Sur Using an Nvidia card. Also the link for the microcode update is offline since at least one year. Please explain me how.
