Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Thank you!
dp/hdmi audio still don't work.
Here is my system info and connector. But i don't know if this has issue.
...

This is one of many reasons why we do not recommend using iGPU. An AMD GPU is strongly recommended.

 

[CaseySJ]

here it is.

Are you using the Z490 Vision D? If so, please mount EFI partition of the macOS SSD, expand the files/folders in the EFI partition, and post a screenshot (do not take a photo with your camera).

A screenshot can be captured by pressing CMD-SHIFT-5 and moving the mouse on top of the window to be captured. The capture file will be saved to the Desktop.

I created that SSDT originally for Z390 Designare, but it does not work in Z490 Vision D. Fortunately there's no need for it on this system. Its purpose is to hide the Intel CNVi WiFi module from macOS.

In my case im using a Asrock Z490 ITX TB3, and i replaced the original wifi card with a BCM94360CD since CNVI is unlocked. So this is something I shouldn't use at all I guess.

Thank you!

These are good points that I hope future versions of OpenCore will address:

• It should be easier to hide EFI partitions without having to create custom entries for Windows.
• Regarding Catalina Backup drive, it would nice to have the ability to hide specific drives. In my case, the bootable backup disks are mostly 2.5" SATA SSDs mounted in a US$9 external USB 3 enclosure. When the enclosure is not connected, the drive of course won't appear in OpenCore Picker.

Agreed! It would be nice to not have to create custom entries for any of this! Having said that, this morning I succeeded in hiding my Backup drive. Just need to figure out why it is defaulting to the generic hard drive icon now

You raise a valid point in that maybe I don’t need to have my backup drive installed in the machine. I just found it handy that I could also store the clone of EFI on that too, meaning if anything goes south, I just boot from that efi/drive and clone everything back to my main install.

I have a potentially stupid question - do I need a copy of my EFI folder on every HD with a mac os install on it? For example I have in my system 3 SSDs - Catalina (startup disk), Catalina Backup, and Big Sur.

Thank you so much for all the help. Maybe not the right place, but if I may ask:

After watching this I became a little confused if I should use the iMacPro1,1 or iMac20,2 SMBIOS.

I'm using a 10900K with a dedicated RX5700 XT

As you can see from this graph, with the iMac SMBIOS, a dedicated GPU and using the iGPU in headless mode, the rendering times are just away too long when compared to the iMacPro1,1 (no IGPU supported, only using the dedicated GPU).

Correct. It may not work on ASRock motherboards because it’s looking specifically for an IOReg device called CNVW.

Bootable backup drives MUST by definition contain a copy of the EFI folder. It is the EFI folder that makes the drive bootable.

The OpenCore Zip file in this thread accommodates both Catalina and Big Sur so one EFI folder can be used to boot both operating systems.

I was just thinking as my backup drive is installed internally, and I can use the same EFI for all 3 drives, could I (and would it be reasonable to) have a small USB stick plugged into the Hack at all times, with that EFI folder on it, to save me having to copy the EFI folder between all the drives every time I make a change?

We discussed this chart by Peter Paul Chato soon after the video first appeared. This is why the Z390 Designare build guide provides this chart:

You're welcome to experiment with both iMacPro1,1 and iMac20,2.

That's not recommended because:

• Carbon Copy Cloner can run EFIClone.sh to back up the EFI partition automatically. This is something a human might forget to do.
• Bootable backup drives should ideally be 100% self-contained.
