@fabiosunHah, ow, woops! I remember something going wrong there a while back. I'll stick to the account that actually has posts then 😄 Sorry for going offtopic. When all is ready, I'll jump on the B550 (Probably VISION D), 5900X, and 6800XT bandwagon. I got a feeling macOS support is going to be A-OK, so let's hope that holds up. @ckrueger99 There's indeed a good chance of Radeon VII's coming available, but the people who have them would sell them to upgrade, and seeing their price point and thermal limitations, I think most new userse would opt for a 6800 (XT) as well. Still, the VII's are great cards! @Jaidy This really is the drag between Apple and NVIDIA. NVIDIA writes all their stuff as closed-source as possible, so reverse-engineering an up-to-date driver for macOS, especially with full-feature support like CUDA, seems highly unlikely. AMD GPU's simply can't produce CUDA results, because they lack the specific cores in their architecture; it's NVIDIA-only as far as I know. AMD uses Stream Processors and Compute Units, which serve a similar function but are ran on OpenGL rather than CUDA. Besides, with the 6000-series AMD GPU's around the corner, there is little reason to prefer NVIDIA over its AMD counterpart.

@fabiosun I also could now passthrough the "USB" Audio Device, due to the updated kernel patch that we were looking for before. I'm still having trouble with the actual sound, it's loud screeches / scratches / noise, nothing you'd like to listen to. Did I miss something, or are you at the same point still?

@iGPU The MacPro7,1 also utilizes multiple GPU's (basically Radeon VII, the Radeon Pro Duo = 2x 40cu Radeon VII which has 36cu), but it's not CrossFire anymore. AMD's recent Pro cards have a variant of Infinity Fabric (like the SLI / CF connector, but $100-200). macOS doesn't mind multiple GPU's, and it sees them typically as separate units, but allows them to work in tandem if the application supports it. I'm excited to see your TB3 progress. I know the PCI-E / PCI ID layout can change drastically when changing components. This basically means that if you can't use the host to edit anything (like me, I'm always cut off and have to use the network web client), if you change a a part there's a chance LAN devices will switch names, and all that jazz. I've locked myself out a few times now, so I make practice to keep a recent backup of the few main files; it's easy to put them back if you have 'm written down. Initially I was able to reboot my system within the VM without running into a "macOS disk not found"-type of message in the macOS verbose bootlog. I changed NVME's around, so maybe that's the reason. I believe I had it in 01:00.0 first, and now it's in the other part, with 43/44:00.0. There's many iffy things to look at, and the struggle of changing around components when trying passthrough, especially when already configured, is a real pita. @fabiosun I can imagine using a supported USB or PCI-E audio card will get us ahead very quickly, compared to fighting against AMD's funky PCI-E/USB audio layout, ProxMox its layers, and macOS its unofficial kext support. With the TB3 card working (which is good news for any system that has TB3 and wants passthrough), I think our options of having a sound card are good. I see why you want to use the onboard though. Such a "simple device" should "just work", right!? To all, a general tip in addition to the fact that you can edit the Clover / Opencore ISO file when finally arriving in macOS: I keep a "failsafe" copy of the initial OpenCore.iso, so I can easily swtich back and forth between my edited EFI, and the failsafe EFI. Plus to that, I have zero trouble booting from the NVME disk its EFI partition, when all VM disks are disabled, and only my datadisk is passed through. QEMU finds the right EFI only then, as we know setting it as a primary boot device in QEMU doesn't really seem to work (or did I miss a memo?) PS: I have sucessfully upgraded to 6.2, but I can't get my VM to boot at the moment, so working on that.

@Driftwood Note I had a similar problem. I would seemingly randomly lose connection to the host. I have two NICs, one setup to passthrough, one dedicated to ProxMox. What happened? They changed device names. This maybe happened because I added a third (Thunderbolt) NIC which also took a name. In the end enp68s0 jumped to 69, 69 to 70, and there was trouble. This seemed fixable by adding in GRUB_CMDLINE_LINUX_DEFAULT "net.ifnames=0 biosdevname=0", or a variation of it. Anyhow, Predicatable Network Naming is a thing: https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ - I'm not sure if it at any point helped me, because after a while of using said GRUB line and having them renamed to Eth0, and Eth1, I manage to break the thing again by messing around with other network settings. After that I reinstalled and let normal names be used, and just make sure I don't add a third NIC. Also note I seem to need to use a RadeonVII ROM in order to boot past the last stage and enter desktop, but I'm using Whatevergreen.kext and no boot-arg (OpenCore) that could allow losing the ROM file. There may be a way. @iGPU It's great to see you're so headstrong on getting TB passthrough to work! If I can do a test, let me know. I'm currently a bit overburdened, so I can't invest a lot of time in this whole project anymore. I do read up, like now. @fabiosunI see you're trying to get the audio fixed. What I read in the links you supplied is that the audio device on TRX is not a typical device, but a two audio chips bridged over USB, which makes things overly complicated for VM passthrough. The FLR patch doesn't seem to work for my TRX40 Designare. Now I note that this is a snippet of the patch: +/* FLR causes Ryzen 3000s built-in HD Audio & USB Controllers to hang on VFIO passthrough */ +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_AMD, 0x149c, quirk_intel_no_flr); +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_AMD, 0x1487, quirk_intel_no_flr); But, my ID's are 148c(!), 149c, and 1487 (audio). 149c was already doing fine, and 148c seems to remain problematic: 03:00.3 USB controller [0c03]: Advanced Micro Devices, Inc.

Can someone hint me on how I can apply a modified FLR patch? I don't really understand whether I need to recompile the kernel or I can just "patch-in-place"? I can perhaps help solving the passthrough audio mystery 😉

@Driftwood - I'm responding here rather than in PM, as it hopefully adds something useful for future people. I was having a breeze the first install following only fabiosun's post(s) initially, but it soon became clear solutions to stuff I was looking for meant editing parts of that initial work. Their great writeup and development of ideas is very useful to read through, as a primary resource. Now, looking at Pavo's repository for quick patches, and Nick Sherlock's fine guides you'll find OpenCore.iso, use that for now it should work fine to start the VM. You will want to grab the Base_System.iso (conver .dmg file) which is 2GB in size. I never got the 9GB installer image to work, only the net download. Make sure you have some LAN connected via VM, because you're missing .kext support right now in OpenCore to passthrough use the LAN ports, probably.I can't tell any other problems looking at your 1##.conf. You can compare your VM config to mine, as I posted above. Just ignore all the hostpci parts for now. If you have the option you can also install macOS on a disk before you use this setup. It's much easier that way it seems to me, as you can skip all the virtual disks if you want, and straight-up passthrough the SATA / NVME drive, and have OpenCore.iso boot into it for you. Then, you can mount the EFI partitions and copy over the OpenCore.iso config, so you can edit and boot from your actual drive, and comment out the OpenCore.iso even, as a fallback if you mess up your editable EFI partition on the drive.

@iGPU Happy to be of service! Bloody, you can "only" pass through 16 PCI devices in ProxMox, hah! Note: I have had my LAN <> TB2 adapter + TB2 <> T3 adapter passed through directly (no other TB-parts, only defined in vfio.conf) as a PCI device.

It's my next task, besides some system overclocking and finetuning 😉

@fabiosun Thanks for all your help already! I believe I'm at about the same spot as most of us. The VM is working well, but I have trouble with two USB controllers, Thunderbolt, and audio. I will look into using the TB card with flashed firmware and see if I can provide some feedback on it, hopefully. @iGPU I can really recommend the Radeon VII, besides that I've used it for many builds, the card passed through perfectly fine. I'm using a rom from the Techpowerup VBIOS database. I can test later whether it's even needed. I have no reset / restart bug related to GPU. Oddly enough, after remaking my VM, I now have the problem that I can't reboot otherwise it will get stuck booting around APFS/HFS, and claims my passed through disk (43:00) isn't accessible anymore and I have to >reset the system< rather than the VM. I didn't have this problem before, but due to other issues I had to remake. In other words: I was using a Radeon VII and a passed through 1TB 970 EVO without problems restarting, before this remake. The difference is that I am now passing through the entire NVME Controller (43:00.0) rathern than /dev/disk/by-id, which you can see in my previous post. Perhaps there lies the difference. I saw some talk about passing through WiFi+BT. macOS doesn't accept Intel WiFi cards, period. You can get a Dell DW1820A for about €20-25, and use only BrcmPatchRAM (Injector + Data + PRAM3), then it's like having native Airport and BT. I'll post more when I know more, and try to keep the questions limited.

Thanks for your quick and elaborate response. I appreciate it a lot @fabiosun! I missed your QEMU-UEFI fix, cheers! What type of misbehaviour do you mean, when all args are deleted? Do you reckon it's CPU TSC related, so stuttering? Perhaps VoodooTSCSync.kext (set your core count -1 in its info.plist) or it's modern alternative TSCAdjustReset.kext (no modification needed) could help reduce this, as well. From what I understand the -args section enables CPU features, so it's surprising that macOS runs without and Cinebench actually scores better!? If the patch for seeing Threadripper is none more than visual it's not worth the GPU slowdown, imo, yes? How did you run the Broadwell topology though? Do you have virtualsmc.kext enabled for this? Right now I can boot without this kext, but I didn't test it when changing topologies around. I think I already saw a few tips and ideas in pavo's repository, so thanks for that link!

Heya! First answers: 1/ The initial line or "args" wasn't copied properly. It's complete, as far as I can tell. 2/ Fixed, only passing through vmxnet3 at the moment, will fix later 3/ Sockets 3x16 is still necessary to boot past the OpenCore picker (menu), otherwise it gets stuck at the screen between this and the macOS logo / verbose. Maybe some OpenCore setting can fix this. My best guess is that the CCX setup of our chips (24c vs 32c) are different, and that our bootloader has difficulty launching with an odd setup of cores/CCX, or something. Note that the 3960X has 4x 6-core CCX's (with 2 cores disabled per CCX), whereas the 3970X has full 8-core CCX's. Perhaps it's also related to the VM CPU topology (will research). With OpenCore 0.5.8 I can now use 120GB of RAM in the VM. All works well, though, with 13564 points CB R20, 1274 / 22198 GB5. 4/ NVME passthrough succesful, besides QEMU-UEFI not saving boot selection. My questions: 1/ Can you tell what you did to achieve higher CineBench scores? You noted "I found something" but not what you did? Did you turn on XFR / PBO in the BIOS for higher boosts? Noted here; 2/ Can you tell how you have macOS / Cinebench the CPU type as our Threadripper rather than Penryn? Is it only a visual edit in macOS, or are there performance implications? I noticed this post on CPU topology. I set my CPU topology to "host", but macOS still thinks of it as Penryn. if I change the "args" line from Penryn to Broadwell (your example) I boot into a black screen in macOS (1x 48 with or without NUMA never works regardless of topology). I'm probably missing something important here. 3/ I'm having trouble passing USB / Thunderbolt PCI devices. I can only pass my 2x USB2.0 (48:00.1) and 1x USB 3.1-A + 1x -C PCI device (48:00:3). Other controllers show "waiting for device, timeout" in Syslog. Is there anything specific that needs to be done to pass more USB devices? I currently have the BlueTooth (USB) part of my chip passed through like usb0: host=7-5, because of the problems with passing through other USB controllers. I have switched the Intel chip for a DW1820A, which is perfectly supporting in macOS by using BRCMPatchRam (BTInjector + Data + PRAM3). WiFi works OOB, but to be sure I use AirportBrcmFixup for fixes. 4/ I recall having my Thunderbolt Titan Ridge AIC passed (partially?) when I was testing Manjaro KVM in December, but right now all PCI ID's related to the TB AIC give the same problem as the USB devices that aren't working (timeout); 5/ Can you give a hint on where to look for sound support? I understood a straight passthrough for the ALC chip doesn't work properly; 6/ I understand that ProxMox / QEMU-UEFI has trouble booting from passed through disks, like I did with my NVME drives. Only solution is a QEMU EFI? Or is there a way to force booting from the NVME. It works fine if I do it manually in the QEMU-UEFI. Did you get an answer to your question?. It's no drama to manually select, but it would be nice if it boots on, otherwise I have to reset the system if I fail to interrupt the wrong boot...

Cheers @fabiosun EDIT: I was quite sure I tried this last night, but after removing the VMWare monitor my problem is basically gone. There is no Console output anymore, but I can use the system as it is now. Sorry for the confusion, the simple solution was to remove the default VMWare monitor.

I didn't properly check which network adapter is actually providing connection, so I have all four options enabled.

I followed @Imanol5700XT description for my Radeon VII, and it seems to work. The problem is the ProxMox Console gets stuck at the last line while starting macOS (IOConsole etc.), and the monitor(s) connected to the Radeon VII will turn on. macOS is setup as "extended displays", so my two physical monitors are empty, and the main display is not properly opening in Console. Is there a way to fix this? I would like to either only use physical monitors, or have a working console monitor.

EDIT: My question is solved (for now, will have to check performance) here with 3x16 rather than 48. Link: Hiya, I have some issue relatively early, pre-install, during Clover boot. I'm an experienced hackintosher, and the information I found was that it's a memory allocation issue, which people solve by moving RAM sticks. I changed the assigned RAM from 125GB to 64GB to no avail. It turns out Clover 5007 may have this issue, but a newer version doesn't. I would like to use OpenCore straight away, or the most recent version of Clover. How do I attain a .iso file that can be used as such? I'm not sure how to make an ISO out of a Clover / OpenCore EFI folder. My problem (10.15.4-related with Clover, apparently), see screenshot. PS: 11.05GB RAM @ 0MHz hahaha

Thanks for all the welcomes 🙂

Hello peeps! I'm writing an introductory post because I understand this to be necessary to download files on the forum. I'll let you know what my plans are, and that is to follow fabiosun his seemingly excellent ProxMox guide, in the hope to get this 3960X Threadripper chip working with Catalina. I appreciate all the work that has been put in by so many people over the last decades to get so many variants of systems running with macOS, it's a treat!
