[Success][Guide] OpenCore Gigabyte Z490 Gaming X i7 10700 (Big Sur 11.2)

[vietxitin]

I've got a similar setup but cannot get hardware acceleration to work. I've got a Gigabyte Z490 Vision G, Intel I7-10700K, and 580 GPU. I've mapped my usb's, tried SMBIOS 19,1, 20,1 and still cannot get my monitor to give me different resolutions or hardware acceleration to work. Any ideas?

Please try SMBIOS iMacPro1,1. I used this SMBIOS it work smooth than iMac 20,1

Using the iMac Pro SMBIOS is fine when you have a CPU that lacks an IGPU, i.e. ’F’ type Intel CPU or AMD CPU. Alternatively when you have completely disabled the IGPU in the BIOS.

It is not the best choice when using a compatible and enabled IGPU. The presence of the IGPU messes with the system in macOS.

If the iMac 20,1 SMBIOS is causing graphics issues it probably means you have not set the graphics properties correctly.

OpenCore 0.6.5

I attached the updated EFI folder for OpenCore 0.6.5 in this post... still needs some testing (it is working for me, files are up-to-date but I had to use 064 config.file to get it to boot). Remember to edit the config.plist and put in your own MLB, SystemSerialNumber and SystemUUID.

Update Jan 15, 2021: Working OpenCore v0.6.5 attached in the 1st post.

Release Notes: https://github.com/acidanthera/OpenCorePkg/releases

@Railgun not booting on my side. Getting loading image file error and after that error, restarting auto and getting boot menu. This steps repeats.

 

[Railgun]

Please try replacing the config.plist with your previous working EFI config file.

I will have to test some more.

 

[lifteri]

@Railgun replaced my old config.plist and system booted. Will wait for your updates.

Thanks

Also i applied boot menu theme

Update: OpenCore v0.6.5 working... Attached in the first post.

With new changes and per Dortania's OpenCore Install Guide, I am now able to boot with iMac20,1 SMBIOS (recommended for i7 10700 and below).

I had to remove a new entry called "MaxBIOSVersion". I did not find documentation on this in the 0.6.5 release notes nor in the guide. I found info regarding it being for OpenCore 0.6.6 which is still in the works.

* New version of ProperTree is out today.

**Remember to edit the config.plist and put in your own MLB, SystemSerialNumber and SystemUUID. I used latest version of GenSMBIOS to generate iMac20,1 info and checked the serial number with https://checkcoverage.apple.com remember if it says invalid, you can use it.

***If you have trouble with iServices, you may need to use your own ROM. It is explained here (look at the ROM section of the page): https://dortania.github.io/OpenCore-Post-Install/universal/iservices.html edit the section in the config.plist file under platforminfo.

ProperTree issue seems to be known by the developer. Here is the verbiage from the ProperTree Github site:

• ProperTree crashes on Big Sur (macOS 11)
  This is due to the default python installs on macOS leveraging an older tk version - which lacks support for macOS 11. To solve this, you can download and install the latest python 3 version from https://www.python.org/downloads/mac-osx/ then leverage the buildapp-python3.command from ProperTree's Scripts directory to build a .app bundle that will leverage that python version.
  If you already have python 3 installed via brew or another package manager - it is likely still linking to the system tk version, which will still have issues unless linked against a newer version.

I updated my Python install to 3.9.1 (latest release) and still have the issue that ProperTree won't open. I deleted the ProperTree app I had built from the Applications folder, rebuilt the app with the latest ProperTree release, so the old system tk version would not be used.

However, the same issue arises, I still can't open plist files with ProperTree on Big Sur 11.1.

Python 3 installed via brew. Running command:

python3 ProperTree.command /path/to/config.plist

command working, using Big Sur 11.1

@Railgun updated to latest efi with latest config.plist with my custom boot menu theme modifications, now its working.

I am using iMacPro1,1

Also i updated my bios version to latest, F20a

Still my sleep wake problem continue.

Update Notice: I have re-written and updated most of the guide.

1. Now reflecting only macOS Big Sur install instructions.
2. Added use of EFIAgent an easy little app for mounting EFI partitions.
3. Instructions on how to use GenSIMBIOS for fixing iServices.

The attached EFI files are OpenCore v 0.6.6.

Release Notes: https://github.com/acidanthera/OpenCorePkg/releases

Hi, Railgun,

Thanks for the guide. I read through your thread and Open Core set up as well. I followed the instructions there and went so far. The Opencore loads up a bunch of stuff and then I can see it's restarted. But it went to blackscreen and stay there. Here is my log file and EFI zip file. Please take a look at it at your earlier convinience.

Thanks.

I have not been able to get the internal UHD630 to work on Big Sur. You may only be able to get going with a dedicated external GPU. Have a look at:

[lifteri]

Updated bios version to F20b
Updated EFI folder with latest OpenCore v 0.6.6 EFI (after applied boot menu theming)
Updated to macOS Big Sur 11.2.1

Sleep wakeup still not working for me, but other things working well.

@Railgun do you have any idea about 6800 XT works on this setup ?

I am using 5700 XT and i want to switch to 6800 XT.

Do you have any idea ?

 

[DigiAU]

Thanks for your suggestion, dkjackson. I'm installing Catalina, not Big Sur. My last build is Z390 system and it went through very smoothly. Really stuck on this Z490 build for myself.

Do I have to buy a video card ?

Any other suggestion is much appreciated.

 

[Railgun]

DigiAU, in your config...

• ResetLogoStatus = Yes but should normally be No
• AAPL,ig-platform-id = 00009b3e - iGPU may not be set correctly. Please read the DeviceProperties Docs
• You can remove the OpenShell.efi (optional)

This was checked by OpenCore config.plist Sanity Checker: https://opencore.slowgeek.com a great tool to use for checking and catching issues.

Thank you very much for your reply. I'll give it a try after work tonight.

Finally, I have Catalina installed successfully with a 580XT video card. Audio and sleep are working but no Ethernet. I can't see the network card.

Does any one have the similar issue? How to fix it, thanks.

Your motherboard uses an Intel 1GB Ethernet controller. So try adding IntelMausi.kext to your bootloader‘s kext folder.
