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

[CaseySJ]

Successfully updated to the latest Big Sur, and to OC 0.7.4! Also installed the 5700XT with no issues. It feels much faster than before, even before the new GPU install (I was running an RX580 pulse before this).

That's more like it! You have finally upgraded to Big Sur only to have Monterey coming out in perhaps a month or less! Fortunately that should be an in-place upgrade with no changes to EFI.

Something I noticed during the OC upgrade with HackinDROM:

What's that last SSDT for (SSDT-Z390-DESIGNARE-TB3HP-V4)? I'm just curious, since it doesn't look like it's enabled?

There are two Thunderbolt hot plug SSDTs:

• SSDT-TB3-HackinDROM --> which is enabled
• SSDT-Z390-DESIGNARE-TB3HP-V4 --> which is disabled

Only one can be active at a time, and the first one is also the latest one.

...
Where should I go from here? I think I'm all caught up? I was reading the table of contents of page 1 of this whole thread, and one thing stood out:

• Enable AppleVTD with No Impact to WiFi and Ethernet

Thoughts on this? You mentioned you'll roll in those changes into OC 0.7.2. I'm on 0.7.4, so I might already have them? I haven't done any Bios tweaks though.

AppleVTD is already configured in OpenCore 0.7.4. It's only necessary to change VT-d to Enabled in BIOS. After that, the setup is complete. Big Sur is awesome so take some time to get acquainted with the new OS.

Hello. I have an unclear problem. I have almost the same configuration as the machine specs in this article. (But GPU is RX5700XT) I'm planning to install Big Sur with OpenCore. After I complete "Spoiler: Quick Reference to Mini-Guides", do I need to make faithful changes to the following articles from "Spoiler: Post-Installation with MultiBeast 11.2.0"?

Also, isn't it recommended to use OC Gen X?

really thank you.

@CaseySJ,

Sorry to butt in, but would you mind clarifying:

My impression was that TB3-HackinDROM.aml is for those with flashed TB firmware, and the older one should be used for those who have not. Is that no longer true?

Thanks as always!

The full guide of Post 1 was created in 2018 and uses Clover. But today we use OpenCore, so we follow the OpenCore mini-guide(s) instead. Multibeast is for Clover, so it’s not used with OpenCore. OC Gen X is not needed either because an OpenCore EFI is already provided.

While it’s true that HackinDROM was originally created for the purpose of customizing the UID bytes of Thunderbolt DROM, it became the de facto standard for everyone regardless of flashed or original firmware. The HackinDROM SSDT is generally preferred for all users because it uses a motherboard-specific DROM instead of a generic Apple DROM.

Thank you for your reply.
I understood that.

I want to know more about the OS version of Big Sur.
Dortania's OpenCore commentary site says

CAUTION: With macOS 11.3 and newer, XhciPortLimit is broken resulting in boot loops (opens new window). We advise users either install an older OS (ie. macOS 10.15, Catalina) or find a 11.2.3 or older Big Sur installer
For education purposes, we have a copy provided here: macOS 11.2.3 InstallAssistant (macOS) (opens new window)
If you've already mapped your USB ports (opens new window) and disabled XhciPortLimit, you can boot macOS 11.3+ without issue.

Should I update the Big Sur OS to the latest version? Or should I stay at 11.2.3? Thank you for your cooperation.

once you have setup your usb ports correctly, you can update to Big Sur, Monterey etc

The OpenCore EFI provided in this thread has a proper USB map with 15 ports defined, and XhciPortLimit is not enabled.

@CaseySJ just dropping in to say thanks for the tip about clicking through sections of OCC to update schema. Using my previous Config.plist and just clicking through the sections in OCC has been a major time saver in the update process.

I manually put my hack to sleep when I get up, but it seems to turn back on after an hour. I have a feeling it could be a USB device.

I'd like to try this fix:

• Disable Wake from USB (Wake only with Power Button)

It seems to only be for clover though. Is there a comparable procedure with OC?
