Your bugs are weird !
Did you change the WiFi card ?
Because it should be simple with this card ?

for a 3950X I would take a x570 from gigabyte or ASUS :/

I did not change the Wifi card, actually I'm ok without Wifi, as latency over Ethernet is much better.

It's the cheapest board in iTX size, I did not want to spend money unnecessary on board, but instead on CPU.

I tried the AppleIntelWifiAdapterV2.kext as this board has an Intel AC 3168 chip, but it made no difference, it's not recognised.

I saw that... but that’s not a good idea IMO.
The 3900 and 3950X are high end CPU and need a good mainboard because they run very hot ! You can break your MB with this. For 30-40$, you should make an effort.

and take a Broadcom card, you will have WiFi/BT/continuity without kext (the bcm94360ng)

it’s my advice, do as you wish...

you need to read this :

update: I managed to get iMessages working

the problem was that I overlooked the fact that it's not enough for the Ethernet to show up as en0. It also has to be 'built-in' !
So back to dortania 'Fixind Services' , found the PCI root of the network controller and appied the patch as by the guide.
iMessages started working immediately, although I was afraid that after about 100x failed activation attempts it could have been blocked on apple side.
It's very easy to check if your network card has this flan on or off with Hackintool.

update: although I don't need Wifi, as for testing I tried installing the itlwm_v1.0.0_stable.kext + the Heliport app and wifi is working, but with poor performance. It's not a native support btw. Handoff and Airdrop not supported. So it was just a test, deleting these now.

I'm done with the USB mapping. I think this motherboard might heave a front side USB-C port, but by case doesn't have a connector for that - I think so because there are some unused ports with lower values in the list.
There's one "personality type" I could not try on USB-C port > an iphone or ipad connected via USB-C to USB-C port as my iPhone has a Lightning port.

Unfortunately USB mapping brought no change to restart / shutdown.
Here's what I have tried so far:

- tried disabling USB controllers separately in USB mapping kext by deleting entries in the usb mapping kext - no change

- tried disabling USB controllers in BIOS separately - no change

- tried removing SSDT-USBX.aml but keep the port mapping - no change

- tried with board specific SSDT-EC-USBX.aml (that I created using the "SB_.PCI0.SBRG" as a path for the Embedded Controller and keep the port mapping - no change

- tried restart with usb devices removed - no change

- tried with 'AppleUSBHostMergeProperties' and also 'AppleUSBMergeNub' in port mapping kext - no change

- tried the 'Fixing Shutdown/Restart' from dortania guide - no change

update:

after 2 weeks of learning and experimenting, restart / shutdown / sleep finally works like a sharm.
I never thought such basic features working will ever make me so happy.

Since the initial install I had about 3 system freeze, and today another one. Previously I had no time to take a look at crashreport, but today I did.

The report shows the one today was related to bluetooth. As I'm not using it, I disabled both WiFi and BlueTooth in BIOS. We'll see if it brings more stability.

update on overclocking:

I spent a whole day investigating the overclocking subject.
I was of the belief that the AMDRyzenCPUPowerManagement.kext provides energy-efficient usage only.

After comparing PBO (Precision Boost Overdrive) to overclocking via frequency adjustment + voltage lifting in Windows I came to a conclusion that I was mistaken.
AMDRyzenCPUPowerManagement.kext not only handles energy efficient usage but also Overclocking within safe limits - and even better, providing superior performance compared to overclocking with the official AMD Ryzen Master app on Windows.

On Windows I got only 26.520 with V-ray Benchmark however with Catalina 10.15.7 27.892

I consider V-ray Benchmark the objective performance meter as it pushes all cores to maximum all the time,
and that's what's important in this case as this configuration is going to perform as a heavy load 3D rendering machine.
Geekbench on the other hand tests multi-core performance for only a very short period of time, hence the results are objective and are not the same on the same machine using different operating systems.

I was unable to run this configuration with the 4.4/4.3 GHz + 1.34 Core voltage setting, the machine crashed / restarted quite quickly. My guess is that for frequency boost + voltage setting adjustment kind of overclocking a memory module of 3600 MHz with a more expensive 'die' is essential (manufactured by Samsung and named B-die... then sold to all other brands). So the only option I had left was PBO and based on temperature and CPU frequency diagram I think that AMDRyzenCPUPowerManagement.kext uses this approach.

After you add the above mentioned kext + the accompanying VirtualSMC.kext, and inject them into config.plist, you restart, install and open the "AMD Power Gadget" app, hit on the red 3500MHz button under "Speed Steps" and enjoy the performance boost.

A note: Ryzen CPUs have built-in performance cap limit that is engaded when the CPU reaches the 64 Celsius value, and you can't push it to a higher frequency when at this temperature. Watching the AMD Power Gadget we can clearly see the CPU cores are forced to operate at 4.1 GHz. However when the temperature is low - for example the start of the testing when the base temp is still around 32 Celsius - the CPU cores can jump to 4.5, but because the temps reach the value of 64 C very quickly the frequency drops to the steady 4.1 MHz in a few seconds.

If my observation is right then buying the big brother of my cooler, the: ARCTIC Liquid Freezer II 360 ( I have 240) and also a bigger ATX case (I have iTX) could in theory bring slightly better cooling performance, and maybe, just maybe squeeze out 1 or 2% more performance out of this CPU.

I've created a USB mapping by following the dortania guide. It's not enough but essential. What's important is that the internal port of LED controller (that's attached via USB) should be skipped > NOT included in the mapping, as that's what causing the inability to restart / shutdown on some of the B550 boards that come by default with LED controller.

Man thank you for the advice. It was the same LED controller in my motherboard too. Now restart/shutdown are OK.

what board you have?
by the way: I made an edit suggestion to dortania to include this fix into post-install fixes, as I saw a bunch of people complaining for being unable to restart/shutdown

CPU: AMD Ryzen 9 3950x

Can you run this test in Xcode 11 or 12?
Xcode benchmark

There's a detailed instruction how to setup the test properly – basically choose Xcode benchmark scheme and Generic iOS device as target and press Cmd+B as soon as that's done. There's also a simple command line which enables showing build time in the toolbar.

I'm interested in two things:
  • are all cores saturated during build (iStat Menus can show you that)
  • what's the total build time

sure pal, I like benchmarks so much that I eat them for breakfast :D

so, I've followed the instructions...
  • there is no Generic iOS Device, i guess 'Any iOS Device' was meant by the author
  • the test took 12 sec to complete
update: on second and third try it's 28 sec (I have deleted the DerivedData before between tests)

Ah, that’s just one of the modules, not the whole thing. Tap where it says “gRPC...”, select “Xcode benchmark” and then “Any iOS device” as you already did.

Make sure to delete derived data first, which forces Xcode to re-compile all the dependent modules and then the main target. Don’t bother with restarts, turning WiFi off or any of that. Just clearing derived data is enough.

I’m hoping for a result between 160-180s.
