@blazinsmokey Hi, I wanted to know if your guide and attached EFI is also compatible with a MB ASUS Maximus VI Formula (1150 Z87) ?

-my configuration has an i7 4790K and a RX580 N+ 8GB

Maybe, I'm not sure of the nvram situation on 8 series boards, my efi might work you'll just have to try and find out

seems to work without problems, do you think the ACPIs need to be reconfigured or can I use them as you configured them?

-the only thing that doesn't seem to work is the wifi, but I'm already working to correct the problem.

- Could you please tell me if there are any known problems I should be aware of or should I check in my system ?

You'll def need to map your own USB ports but if power management works, guess it's all good.
 
I got this to work for an ASUS Z97M-PLUS. No USB Flashback on this board, the patched BIOS had to be updated the hard way. Finding a way to flash the modded BIOS was a drag. I ended up flashing it from within a running Windows 10.

For those who wondered (I did :)): using an old and ancient BIOS with a working NvramSmi driver didn't do the trick. At least not for me. Not sure why.

Behaviour before patching:
I could start the installation USB with OC 0.6.5 I created using the Dortania guide, format my destination drive using Diskutil from the MacOS installer, then start the installation of Big Sur. When the slider was down to apprx 12%, the system rebooted and there was no bootable "MacOS Installer" entry for the freshly installed MacOS on the destination drive when I entered the OC boot menu again (the menu options were exactly the same as before the installation). I guess the installer somewhere crashed and didn't finished the first install pass in full.

What worked for me:
  • Download the Z97M-PLUS-ASUS-2903.CAP and Z97M-PLUS-ASUS-2202.CAP file from the ASUS website. 2903 is the latest BIOS, 2202 contains a working NvramSmi driver.
  • Use the older UEFITool_0.21.5_osx (as the latest NE A58 can't save) to patch the NvramSmi driver, as described by Blazinsmokey in the first post of this thread.
  • Install and boot Win10 on a SATA SSD attached to the Z97M-PLUS.
  • Use the 'procedure' part in this old post by Fernando to flash the BIOS. I used the part: B. Methods for ASUS mainboards without USB Flashback support, Using the AMI tool AFUWIN.
    • For this, I removed the encapsulation from the patched 2903.CAP file using UEFITool_0.21.5_osx.
    • I used AFUWIN64 tool v3.05.04 to first flash the standard 2903.CAP (without options), then the patched 2903.rom (with /GAN option).
    • After flashing the patched rom version, I rebooted.
Behaviour after patching:
I did the same installation as before. After the first reboot, two extra boot options were visible in the OC boot menu: MacOS Installer and Recovery. The MacOS Installer was the default boot option, so the installation automatically continued as it should.


Thanks Blazin, for this thread! Saved me from tossing away this board and replacing it with a new one!

YOU ARE THE MAN!!!!! Serial Port Disable fixed it! I was regretting switching from Clover for the last couple weeks but you were able to help me fix my NVRAM and Sleep which were my only issues.

Thanks so much for you help!
Hello!
I made EFI for Big Sur update, but it didn't work...
My computer specification is very similar to yours, so I'd like to refer to EFI, could you share it with me?
Thank you!

My Hackintosh Build :
i7 4790K
ASUS Z97-A
GeForce GTX 780 3GB
Catalina 10.15.6 Clover -> Big Sur 11.2 Opencore(test - not boot)

Wanted to give a little update. Today I updated to MonteRey with an in place/direct upgrade (no clean install).

Went fairly smooth. Mostly some RTFM/stupid things.

For future reference:
  • Created a USB bootable drive for testin/experimenting
  • Copied current EFI from boot drive to it
  • Updated OpenCore to 0.7.5 manually (should have used OpenCore Configurator though...)
  • Updated relevant drivers, kext and open core files
  • downloaded and started the Monterey install from the app store
  • waited, rebooted, waited and waited some more
  • Monterey booted nicely but there were boot issues with BT, WiFi and Audio which resulted in errors like:
    • kernelmanagerd stall for BCM20702A0 and pci14e4,43b1
    • and resulted in 240s (3x 60 sec) timeouts after which it would boot
  • Everything boiled down to not having installed the correct kexts or having kexts which shouldn't be there
  • Used OpenCore Configurator to update present kexts (excluding cpufriend)
  • Read through https://github.com/acidanthera/BrcmPatchRAM for details / issues with the BT/WiFi and settled for the kernel config as seen in attachment
  • Did a lot of trial and error rebooting and reverting to the USB drive which contained a "surely booting" EFI
