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

[CaseySJ]

hello casey me i flash the thunderbold firmware on designare z390 and i would like to know if i am this brocedure if i will see a change and if it will work

Hello @Lkevin30,

All real Macs have AppleVTD. Even if you flash the Thunderbolt firmware, enabling AppleVTD has these additional benefits:

• Antelope Audio Thunderbolt devices will connect and work (only with AppleVTD)
• Apple Thunderbolt-to-Gigabit Ethernet adapter will connect and work only with AppleVTD in Big Sur and Monterey
• If you search for posts by @luckyal, you'll find examples of low-latency audio devices that require AppleVTD
• There are probably several other devices that will only work with AppleVTD...

Sorry if this has already been asked but is USB 3 hot plug still a no-go for flashed GC-Titan Ridge cards on 11.3+?

If you flash the modified Designare Z390 NVM33 file to the GC-Titan Ridge, USB-C ports should work just fine. However, we cannot use some recent BIOS releases that contain support for Resizable Base Address Register (Resizeable BAR). This, however, varies from board to board.

That totally sounds like a plan! Thanks — will try shortly. I'm using it on Monterey and looks like it fixed the issues when AirDrop Continuity Handoff, Connection to AirPods Pro, RSSI stopped working after wake-from-sleep If Apple gives us back Bluetooth API in next Monterey versions I can...

Warning:

• The attached SSDT is only for Gigabyte Z390 Designare only.

@CaseySJ,
After opening up my DMAR tables in MaciASL, I was able to confirm the register base addresses on Aorus Master matched the Designare! After loading the ssdt and delete DMAR portion to my config.plist, all is well!

On a side note, during this VT-d experiment, I discovered that the ethernet port on my Caldigit TS3+ dock was not working- I just never needed it so I wasn't aware. Now, that port is working over Thunderbolt as well!

Again, awesome job @yosoyoco! And @CaseySJ, thanks for cultivating such a resourceful group in this forum!

Yup ASUS X299 is definitely more finicky. Tried the latest resizable bar BIOS and the one prior and same results.

What works

• USB 2.0 cold/warm boot
• USB 2.0 hot-plug
• USB 3.0 cold/warm boot
• USB 3.0 hot-plug
  • Only works if a USB 3.0 device is plugged in prior to boot

What doesn't work

• USB 3.0 hot-plug (after boot)

Just something to watch out for

Just something to watch out for

• Is this with Designare NVM 33 flashed to the GC-Titan Ridge?
• Is this with Big Sur?
  • Same on any other macOS version that you've tried?

** Apple Thunderbolt Display and LG UltraFine Thunderbolt Volunteers Wanted **

Update 7 JUL 2021:
Due to data collection procedure being a bit complicated, we have switched to Plan B.
More information in 2-3 weeks.​

We haven't given up on you...

• We know your monitors may not be turning on during BIOS and OpenCore.
• We know you might be using a ghost plug or second monitor as a workaround.

If you have more than 75 posts and own either an Apple Thunderbolt Display or LG UltraFine Thunderbolt Display, we would like to send you:

• Z390 Designare modified BIOS with Apple Thunderbolt PEI/DXE drivers
• Straightforward procedure to collect UEFI driver data and logs (from UEFI Shell)

If you previously volunteered for the modified BIOS, you're already a step ahead.

@Elias64Fr is graciously working on this challenge. We cannot make any guarantees, of course, but we can make an effort...

Upgraded to Big Sur without any problems. However, I'm unable to use the HackinDROM tool to upgrade from OC 0.7.0 to 0.7.1.

My main system drive has my default EFI, and my backup EFI resides on another identical NVMe. As you can see, the backup EFI which resides on drive called: "Corsair Storage" has the option to update to 0.7.1, but my main "Mojave" drive does not. Any reasons as to why this might be?


I also noticed that after upgrading to Big Sur from Mojave, it appears that the EFI partition was modified and an "APPLE" directory was added, which includes subdirectories called "FIRMWARE and EXTENSIONS."
