GUIDE How to Enable Antelope, PreSonus, Slate Digital, Focusrite and Apogee Audio Interface on macOS

[EliteMacx86]

Hello! I am in desperate need of some help getting my Antelope Discrete 8 Pro SC working over TB3 with my hackintosh. I have a UA Apollo that I have tested hotplug with (and it works), but have not had luck with the Antelope. I've enabled Vt-d and TB in my BIOS, but I'm not having any issues with networking.. So do I still need to do the DMAR section? Also, I'm still not seeing the Antelope interface.

Yes, but not always.

Hello This is my first post here so sorry if I'm doing something wrong but i have a question, at the end of your post you say the for AMD systems I have to use the second workaround but i can't seem to find this second workaround, I did test this method on an Intel System and it works flawlessly but on AMD I have enabled SV-T and IOMMU but i get no DMAR table to edit and I'm confused now...
On the news page you have said that AMD Systems are now supported so am i missing something here?
BTW I do not use a thunderbolt card I use a pci-e firewire 800 card with texas chipset (the same card that i used on the intel system which was fixed with your solution)

Hello This is my first post here so sorry if I'm doing something wrong but i have a question, at the end of your post you say the for AMD systems I have to use the second workaround but i can't seem to find this second workaround

The second workaround suggested in the guide was to use macOS Sierra.

I did test this method on an Intel System and it works flawlessly but on AMD I have enabled SV-T and IOMMU but i get no DMAR table to edit and I'm confused now...

This is because the AMD does not have VT-d. Its simply not supported by the AMD processors.

On the news page you have said that AMD Systems are now supported so am i missing something here?

The process is quite complex and this is why it was never documented.

BTW I do not use a thunderbolt card I use a pci-e firewire 800 card with texas chipset (the same card that i used on the intel system which was fixed with your solution)

And what problem do you have with this FireWire Card?

Hey sorry for the late reply... war 'n stuff happened ))...

On catalina there is no problem on any system but the Problem starts with FireWire card/audio devices on AMD System:
Card gets recognized soundcard gets recognize but the device malfunctions (no sound, inputs work but no output signal (I have the same Focusrite Saffire card that you guys showcased)
On Intel System:
It was exactly as the AMD system but per your guide enabling VT-d fixed everything
On VM's (QEMU -machine q35):
The card is seen by macos but there is a problem that it cannot list any devices and nothing works.
QEMU -machine pc:
is the same as the AMD system

Thing that i have tested:
-Different Firewire Cards (one via chipset one texas chip supposedly OOBE on macos)
-Different Sound cards (Focusrite Liquid 56, Focusrite Saffire 24, Mackie Onyx Blackbird... all dice chips)
-As mentioned above different platforms (Intel, AMD, VMs)
-Different machine type and cpu models on QEMU (Penryn, Haswell, Cascadelake, Host-passthrough)

P.S. I know that Firewire support was dropped on Monetary, needless to say these cards all have third party drivers which makes them work and as mentioned above i know they work because there is no issue on the Intel Hackintosh with VT-d enabled and one more thing my issue is present (on problematic systems) even in BigSur.

Is there any chance you could maybe share the undocumented complex AMD method with me?
I'm no programmer/coder but I know my way around OC and macOS and hardware...

Well, recently had a system with FireWire running macOS Sequoia and works pretty fine with the FW LaCie drives. Did not test any Audio devices though.

That never got fully implemented due to the several issues. Although, we managed to get it working on a couple of systems.
