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

[jiffyslot]

OpenCore 0.7.1 is expected next week. I'll make the EFI folder compatible with Monterey. Intel i211 Ethernet port (driven by SmallTreeIntel kext) does not connect (Monterey).

If you can keep your special 0.7.1 recipes compatible with Mojave, I'll be forever grateful.

That is to have a fully functioning (or as close to a real mac as possible) Thunderbolt. Unlike UAudio's Apollos which use onboard DSP to achieve low latency, most of Thunderbolt audio interfaces out there, require direct access to memory (DMA) typically reserved for virtualization (VT-d). I have helped a good half dozen people setting this up for a range of audio interfaces, from MOTU, Slate, Presonus and others.

I believe (I could be wrong) that in order to have a fully working Thunderbolt implementation, the following need to be true:

1. Enable VT-d in BIOS (assuming Thunderbolt devices are already enabled with 'no security' in BIOS)
2. Remove dart=0 (Boot>Arguments in Clover / NVRAM>Add>boot-args in OC)
3. Disabled SIP (if the installed driver doesn't produce a security prompt to allow driver to function)

Puzzled as I own a fully functioning Presonus Quantum 2626? I guess I could make the changes and see if there is a performance difference but I’m curious about your statement? I run Mojave so it won’t do any harm anyways…

Thanks,

Patrice

I've used a few different TB audio interfaces without VT-d and with dart=0 with zero problems. Also still on Mojave.

@brousseau6933: let me know if you notice a difference with VT-d and without dart=0.

Well, I guess because I'm still using Clover 5099 and a patched OCQuircks EFI driver (old method), I can't see any Apple VT-d entry in IORegistryExplorer. If Im not mistaken, I would have to use a more recent version of Clover while implementing the quirks in the Config.plist. Not worth the hassle now... sorry!

**EDIT: confirmed by looking at Dortania guide that I should tick "DisableIOMapper" be it in Clover or OC. Only way to completely benefit of Apple VT-d in conjunction with removing Dart=0 and enabling VT-d in BIOS.

If ain't broken, don't fix it in my case then

What are the interfaces?

I ALWAYS had to have VT-d enabled to have a fully functioning VRS8 as well as a friend's Quantum on his machine. I use the Designare, he uses an Asus ROG Maximus IX with a Alpine Ridge AIC. A disabled VT-d in BIOS was NEVER an option for me on any system. This has been true since Clover versions 4XXX. I'm not sure if/how you got around this issue, but it may be key to having a working Antelope interface without VT-d enabled. A few posts back I referenced my experience with the VRS8 and point to a post that leads to another thread on this forum where @joevt was instrumental in helping me figure this out. That thread was started by and eventually abandoned by someone who owns a Persons Quantum but had similar problem and couldn't get it to work. Worth reading through the first 20 pages or so.

Presonus Quantum 2626 in my case. Running fine since October under Mojave. Hence my question why DMA and VT-d would be needed…

Will look for the post ´cause I’m curious but my 2626 (not the original Quantum TB2) works flawlessly.

@luckyal ,

@loloduarte owns the TB2 Quantum, not the same as the Quantum 2626. The post referenced someone not being able to have a working Quantum, right? Strange indeed…

**EDIT: it looks they have problems but not on the same board. They are on Z170 and 270.

**EDIT #2: looking at this post: https://www.tonymacx86.com/threads/...io-interface-help.226705/page-10#post-1900936

In your specific case, VT-d was a must. In the case of the 2626, it looks, at least on Mojave, that VT-d isn’t needed for proper function.
