In your Clover config.plist, please try deleting DMAR as shown below (i.e. remove that line), then reboot (VT-d must be enabled in BIOS). Does AppleVTD now appear in IOReg?

Holy cow! @CaseySJ , you're an evil Genius! They should bronze your brain when you're finished with it! AppleVTD showed up and the Antelope device works thru Thunderbolt! Game-changer!:clap:

The only caveat is that I can't daisy-chain my UAD Apollo and my Antelope. When I do, they disappear and Thunderbolt Bus shows up. I'm gonna go get a second TB3 -> TB2 adapter today and try to run them from both ports... AFTER I play with my AFX2DAW effects. :headbang:

Asus X299 Prime Deluxe II
bios 0802
4x16GB G.Skill Aegis 3000 (2) 3200 (2)
Clover 5122
macOS X 10.13.6 (17G6030)
Wifi -> working
Ethernet -> still out, 1G and 5G

Update: Shutdown and started back up in Windows 10 to confirm all devices were attached. Shutdown and booted to macOS X and BOOM, FULL Thunderbolt with both devices daisy-chained!

Not to be a bother but did you have a chance to try activating PTT @CaseySJ? I tried resetting CMOS and enabling PTT before touching any bios settings but it still comes back disabled. Wondering if there could be a problem with my 9900K, or if it's somehow still related to my bios screwup (seems a bit unlikely as I flashed the full chip using your bios).

Hello @SardusX,

It's highly highly highly recommended (i.e. Just Do It :)) to install F9g or F9i. I would recommend F9i. Then unlock MSR 0xE2 just by doing this: BIOS Setup --> Boot --> CFG-Lock --> Disabled. As easy as that to unlock MSR 0xE2.
When you suggest updating with the BIOS version F9i do you mean the "official" one?
I downloaded the F9i version from Softpedia:
and compared its SHA-1 /256/384/512 signature with those of the file You linked in Your "Quick Reference to Mini-Guides and Micro-Guides": they coincide so I can think they are both verified files?

Use the same SSDT-UIAC... that you are using now. Copy that file into OpenCore's OC/ACPI folder and add a reference to it in config.plist --> ACPI section using OpenCore Configurator:

Please, i have two questions:
Is the use of the OpenIntelWireless Driver (and therefore of the SSDT-UIAC-DESIGNARE-Z390-V7D.aml) compatible with the use of iMac 19.1 sysdef?
When I made the first installation of macOS mojave by following your Guide you provided me with the SSDT-UIAC-DESIGNATE-Z390-FD-DEFINE-C-TG.aml file (which I attach to this post). Do you think it can still be used with OpenCore and Catalina/Big Sur?

Thanks in advance

Just walked 2.65 miles down the hill to nearest Starbucks. Will be back soon.

Yes that's the right one (official F9i).

Yes it's compatible with iMac19,1.

When I made the first installation of macOS mojave by following your Guide you provided me with the SSDT-UIAC-DESIGNATE-Z390-FD-DEFINE-C-TG.aml file (which I attach to this post). Do you think it can still be used with OpenCore and Catalina/Big Sur?
...
Yes this can be used with OpenCore and Catalina/Big Sur. It's best to use Broadcom WiFi/BT instead of Intel. There are still several issues with the OpenIntelWireless drivers so I cannot recommend them for day-to-day use.

Just enabled Intel Platform Trust Technology in BIOS F9i (w/latest microcode update from Elias). No problem booting macOS. Will go back into BIOS now to see whether PTT is still enabled.

Update: Yes, it is still enabled. I did not reset CMOS or make any other changes to BIOS. Just flipped PTT on.

Careful, that exercise stuff can kill you. I used to do a minimum 5 miles a day with 80lbs of gear back in the 80’s and 90’s when I was with the Corps. Now my knees and back are a mess.

It's a different equation when the only two things you're carrying are an iPhone and a latté! No stress on the spine.

@CaseySJ @Elias64Fr

...with my Z390 Designare:

I have installed one 16GB memory module (G.SKILL - F4-3000C16Q-64GTZR)in bank A1. Everything works perfectly!

With two, three or four modules the LAN / WLAN is deactivated. It does not matter in which slot the modules are inserted.
