Have you tried with this config to boot with all cores enabled?

if it is not working as I think you can try to use an Xcode app (instruments) and limit there cpu core to 32

it could be possible also to try a boot arg (cpu or cpus =32) and see

 

but no illusion about it because also some important lib should be capped to work

 

only some tries to do!

Yes, it crashes when multithreading is enabled in bios (SMT Mode = Auto).

Testing boot args now, will report back.

Is there a kext that can make it work without turning off SMT?

Another note; Adobe and everything seems to be working so far, but for some reason Autodesk Maya crashes when launching. Very very odd.

Edit; cpu=32 boot arg didn't fix the issue.

Post your config.plist if you can @23d1

Here it is

Ps. Got sound working, Bluetooth mostly working (lots of weird bugs tho).

Big Sur Updated: 11.6.1 easily with latest OC 0.74 (SecureBootMethod=Default) As simply as Monterey Beta 9. Thats all.

 

Any chance you'd be willing to share your latest EFI? I can't seem to get past;

EB|#LOG:EXITBS:START

Which is the first time I run into this issue, having basically figured out all MMIO stuff and so forth prior. Not sure if I messed it up when going from 0.7.2 to 0.7.4, but doesn't work at all to downgrade either now.

Don't remember Hackintosh being this complicated back in the day. 😉

Edit: Out of embarrassment I won't share how, but I Managed to boot, but would still love to compare configs. 😅

@fabiosun I remember you mentioned a potential workaround to boot with 64 cores multithreaded, any chance you could elaborate? I seem to have a solid and stable system at the moment, just need to figure out bluetooth and some minor stuff.

@23d1

yes very happy with bare metal

My software pipeline works at its best

Davinci Resolve

ADOBE creative suite (AE,PS,PR,ME) *

 

you will have same problems with your 3990x CPU (the limit is 64 core (no HT) or 32c +32t)..and this is an old and annoying OSX limitation.

Oh, awesome—similar pipeline as me. I use Adobe CC, Autodesk Maya, Redshift and so forth. Lots of 3D and motion.

I'll jump in the bare metal thread when I have some time (hopefully this weekend) to go crazy and nerd out. 🙂 Grazie mille!

@23d1welcome back

Sorry I have left virtualisation way many months ago and I am not useful to solve this problem 

I hope other users could help you

Ah, you've gone fully bare metal? That would be an option also, but I'm assuming I would run into similar issues. Guess I'll pick it back up, I do prefer bare metal, just the annoyance of turning off hyperthreading on a 64 core CPU. 🙂

Hey guys, it's been a while since I last posted. Finally picking this back up after a loooong time.

I've gotten my hands on a 6800 XT that I initially intended to use as an eGPU, but Apple's Metal API makes rendering on eGPUs very slow, most likely for some clandestine security reasons. Very annoying. In any case, I've gotten Big Sur up and running as a KVM via QEMU on Arch. The intent is to use my Arch install primarily for simulation and rendering, and macOS for compositing and other design tasks (Adobe CC and so forth, and potentially lookdev in 3D using the 6800XT to render).

For some odd reason that I don't know if, I manage to passthrough the GPU with no fuss, but upon loading macOS from the OpenCore boot menu, it simply crashes as it starts loading up. No error or anything, just freezes up and I have to SSH into the machine and kill the QEMU process to get back my USBs and disks that i passthrough (which works great without GPU).

Anyone run into this issue and can shed some light?

@meina222 thanks for sharing! Gonna give it a whirl in a bit. ✌️

@23d1,

 

No issues here. I run 4 VMs - 2 MacOS, 1 Windows 10 and 1 Linux. Had a problem w GPU reset on 5700XT but now this is largely solved (with the exception of DisplayPort). I did multiple Proxmox kernel upgrades. I find 5.4.xx series to be the most performant for my VMs (compared to 5.7/5.8/5.9) by a significant margin so I'll stay on it (latest 5.4.78 kernel and Proxmox 6.3) until the next LTS.

 

What changes did you make between the time you had your VMs working fine and now?

I updated some packages, is all. And the latest dist upgrade as well. I have since tried a fresh install and so on. I got everything working again, but can't get past the reset to OpenCore bug for some reason. I wonder if I need to load some kind of NVMe kext or anything else that might be causing this issue. Any chance you could share your EFI for macOS (I run High Sierra until I can get my hands on an AMD card, preferably the 6800xt so I can bump up to whichever version of Big Sur supports that)?

I have indeed tried updating the intramfs and triple checked BIOS settings and everything is as it was, just simply stopped working. Very very strange.

@meina222 

Quick update; I had to move the contents of the /etc/modules file to /etc/intramfs-tools/modules in order to get it back to working. However, I have the remaining issue that the macOS vm resets randomly to the OpenCore bootloader. This happens both in Proxmox and when launching in ArchLinux. Super frustrating. Thinking it might be the OpenCore bootloader itself, so I'm investigating. Any idea, or ever run into this issue?

Hey guys,

Been working a lot lately, so haven't had time to mess around for the past couple of months, but getting back into it yesterday, I updated my Proxmox install (just the classic apt update stuff, which shouldn't break anything as it's all the stable Debian branch of Linux anyway). For some reason, when trying to start any VM with PCIe passthrough, I get an error saying "Cannot find vfio-pci module", and so it will not start. I pass through all my GPUs to VMs, and it was working great until I booted up and updated the system. Very strange.

Anyone run into this?

@fabiosun Fantastic, thanks! Will try this out after work later today. I've tried every port and BT, so I wonder if it's a missing aml or kext for the specific chipset...

Edit;

I got bluetooth working with IntelBluetoothFirmware.kext, so I could connect keyboard and mouse and subsequently log in. However, while macOS sees the Nvidia GPUs, there is no GPU acceleration. I tried running Cinebench just to see the CPU score on bare metal, but the machine froze completely so I had to hard reset. Will test more later.

when you upload an EFI you can delete Apple folder and also all audio inside resources 🙂

 

try to boot with this EFI attached

You should use it with an High Sierra yet installed because in there there are no kext for ethernet (I do not understand well for your bare metal EFi which one you use

with this EFI I can install/boot from all OSX System..

If we go further we will add kext for ethernet you need

if you are not in water loop (for GPU) if with all 3 GPU fails, I would try with only one in slot 1

It boots! Amazing. Thanks a ton!
The only issue now is that USB doesn't seem to work (no keyboard or mouse, basically).

@fabiosun Thanks man, really really appreciate it. In bare metal, the EFI works for booting the install and getting to about 2 minutes remaining on the install and then it just freezes. When trying to boot my NVMe (Proxmox install) it freezes while trying to boot. No kernel panic or anything, nothing in the system logs, so it's been borderline impossible to debug.

You must off HT because 64 cores/threads are OS X limit

if you have proxmox booting fine you should be able to boot also in baremetal

post your working proxmox Efi if you want and I will try to build an initial bare metal Efi for you 

if you have an OS X high Sierra working well in proxmox you may have to clone that disk and then put there bare metal efi 

 

@fabiosun Yeah, definitely have that turned off when trying. Here's my Proxmox EFI (dropbox link due to file size: https://www.dropbox.com/s/t8aoqeccfynffjw/Proxmox-EFI.7z?dl=0), as well as my (broken) bare metal EFI. Already had the DummyPowerManagement enabled @meina222...

@23d1you do not need of @Driftwoodefi because hig sierra is a bit more complex to rule than newer osx..you also have 3 nvidia and a 3990x

about 3990x

you have to limit your ccd via bios to 2

nvidia is more tricky

you have to find the right ‘alchemy’ with nvram (working or not) and high sierra SIP and gatekeeper...not simple but possible..

I am using a single high sierra installation on my nvme sabrent drive to boot osx in proxmox and in bare metal (different EFI, in proxmox is less patched)

not advisable if you use adobe app but it is possible

 

OT

By the way great works in your site! 👍

Totally get it, but still interested in the setup as I'm hoping I'm just missing a kext or ACPI/config.plist quirk or something. I've tried pretty much everything at this point, even unplugging GPUs, moving components around and so forth. At least Proxmox works, but initially, my plan was to run macOS from my Arch installation, where I have all the 3D tools I use (Houdini, Maya, Redshift), then use the KVM for Adobe Creative Cloud apps. Is there a way to pass all 128 threads to VM as 64, or would I need to turn off hyperthreading just like bare metal?

OT

Thanks, man! 🙂

@23d1 u installing Cat or BS? Cus I use two different EFIs  whilst BS is in Beta. 

Also I can boot my Proxmox cat m2 drive using same baremetal efi I use for Baremetal cat SSD.

I need both just for comfort!

@Driftwood It sounds like you're doing what I'm trying to do (kvm and bare metal with one macOS install). Would really appreciate if you'd be willing to share your Catalina EFI. Would love to take a look at it and see where I'm messing up currently.

@Driftwood High Sierra (due to 3x1080Ti GPUs—waiting patiently for the Big Navis to drop...) I would assume Catalina EFI should work, perhaps adding the Nvidia boot option.

@Driftwood Any chance you'd share your EFI folder? I have a very similar setup with the ASRock TRX40 Creator, and cannot for the life of me get past the initial install process. Freezes at 2 minutes remaining, and none of the fixes in the OpenCore guide seem to work. I followed it very closely. Right now I have Proxmox running and I've installed on a passthrough NVMe that I want to try and "convert" to bare metal.

Thanks so much, @fabiosun and @meina222 — it seems Proxmox is the way to go with this massive core count. Hopefully macOS will support more cores in the near future, but since Apple will transition to ARM, it's going to be interesting to see everything unfold in the coming couple of years.

Hey @fabiosun, thanks!

Yeah, I've been holding on to the 1080Ti cards for the purpose of using in macOS, but will likely mix it up with the new AMD Big Navi coming out (the rumored 6900xt, if it pans out) to be able to bump up to Big Sur. Definitely gonna do Proxmox. I think my main concern at the moment is the triple-VM setup and how I'm gonna sort out allocating hardware resources. I do a lot of GPU accelerated rendering, and Redshift is coming to Apple Metal (which I'm beta testing at the moment), so if I can get out from the Nvidia strangle-hold, I'll be a happy camper. Worst case I can probably do an Arch Linux setup for the GPU related work, and then KVM into macOS for Adobe and so forth. Gonna be a Frankenstein setup. Hah. 🙂

By the way, I haven't seen anyone have any luck with stable baremetal on the 3990x yet—has there been many reports of success? I'll scour the forum(s) and see as well.

Gonna give this a go on a 3990x this weekend. The plan is to have a triple-boot — Linux / Windows / macOS. Will report back.
