[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

If you have installed a macOS update recently, simply look for an APPLE folder inside the EFI folder. There you’ll find the Apple firmware file.

1) Doh.

2) Darn. Deleted it last week.

@CaseySJ @Elias64Fr I'm looking to play along. Where are you all finding the Apple Bios firmware? I've been tearing through macOS installers and can't get a hit.

Hi @NorthAmTransAm

another way, that you can find it on other MacOS websites, to have all models firmwares (Non T2 chipped) is to follow theses steps :

Spoiler: 1) Open MacOS Install file package

Spoiler: 2) Open SharedSupport.dmg file with DiskImageMounter

Spoiler: 3) Copy the long named file on desktop

Spoiler: 4) Extract this ZIP file and you finally have all firmwares you want on EFI folder (Discrete graphics, SSD, UEFI, Thunderbolt, ... )

That's all !

Booyah. Did it both ways.

Now to watch.

Hi Casey, thanks. It always fails on the final boot, the one that would take you to the initlal account setup. I think that's reboot #3 for Big Sur.

I just now reverted back to F9i and I'm going to try again. I'll edit this later on tonight.
Update: Ah ha! All signs point to a problem with BIOS F9k. I flashed back to F9i, installed Mojave, then updated to Catalina, then updated to Big Sur.

Glad to hear it.

Reminder to all: Please do not use BIOS F9k. Instead, use any one of these:

Hey @CaseySJ
opencore config set to 0.7.0 Release
here's my ACPI screenshot
what do you think boss?

That looks correct.

• What is the make/model of your Thunderbolt device?
• When did hot plug stop working?
  • When you installed modified BIOS F9i with latest microcode?
  • When you updated to OpenCore 0.7.0?
• Do you have other Thunderbolt devices?
  • If so, do they hot plug correctly?

You guys are always having so much fun over here. Glad I stopped in to see what is going on here.

I have the Z390M gaming motherboard with a flashed Titan Ridge card and Apple Thunderbolt Display. The only issue I have is the display doesn't turn on until about halfway through the boot process. Really not that big of deal, but always ready to do some hacking.

I have this is the Apple folder of my EFI. What do I do next? I am running Mojave if it matters. I am loading two SSDTs to enable the TR thunderbolt bus along with using the Z390 Designaire firmware on my TR card.

Hello @nottooshabby,

@Elias64Fr is still focused on the Z390 Designare. We will complete the experiment/test process on this motherboard and then decide what to do next. I expect that everyone with a Thunderbolt-capable motherboard will want this BIOS mod, so I need to set the expectation straight right now: Our priority is to perform the experiment only on the Gigabyte Z390 Designare at this time.

So, I have come to conclusion, that HEVC encode in Apple apps is completely broken on dGPU on Big Sur for now... Handbrake works (videotoolbox), but FCPX and quicktime does not

Any thoughts? Anyone? Does anybody have HEVC encode on Big Sur?

This was already asked by @NorthAmTransAm and replied to. Just jump back a couple of pages.

I guess by your post here: https://www.tonymacx86.com/threads/...700k-amd-rx-580.267551/page-3165#post-2256392

… that the answer is « yes » as you mention the need to modify 3 or 6 bytes. Am I correct?

Thanks,

Patrice

Yes, that's correct.
