Sorry I don't have any AMD kit to test this, and I am reliant on others who test it. It could possibly be due to the Catalina version but I doubt it. If those settings work for you then stick with them. I would also add these 3 lines as well.

vhv.enable = "FALSE"
vpmc.enable = "FALSE"
vvtd.enable = "FALSE"

Ensures macOS does not try to use Intel VMX extensions on an AMD CPU

I started experimenting with settings other than I found to be working because I tried to "show" all CPU features to the guest OS, as my tasks are very CPU intensive, and I wanted to allow the app I'm using to use all available features. But I was unable to find how these masks are created, and what should I change to, for example, "show" AVX2 to guest.

You can setup cpuid masks but they are complicated. Also the CPU must support the instruction so whilst you can spoof AVX2 present the real CPU must support it.

AVX2 off:

cpuid.7.ebx = "----:----:----:----:----:----:--0-:----"

AVX2 on:

cpuid.7.ebx = "----:----:----:----:----:----:--1-:----"

No problem the VMware.log you sent has everything needed. It’s late evening in UK so will look at it tomorrow.

Looking at the vmware.log file, VMware is set that only the following bits are needed for Catalina:

sse3,pclmulqdq,mwait,ssse3,cmpxchg16b,sse41,sse42,movbe,popcnt,aes,rdrand,fsgsbase,bmi1,
smep,bmi2,enfstrg,invpcid,rdseed,adx,smap,clflushopt,clwb,sha,umip,pku,gfni,rdpid,
fast_short_repmov,fcmd,lahf64,extapicspc,cr8avail,abm,sse4a,misaligned_sse,3dnprefetch,
nx,mmxext,ffxsr,pdpe1gb,rdtscp,lm,clzero,wbnoinvd,amd,ibpb

Those are the bits that must be available for Catalina to work, which makes sense based on the CPUs and Apple hardware Catalina was designed to support.

Next question is that Catalina could still use AVX etc. The cpuid bit masks do not stop the guest OS from using instructions unless it queries the cpuid bits first and modifies its code path. Do you know that the software you are using queries and makes use of AVX2, as it could be using AVX2/AVX512 without those bits being set?

Anyways this is the next idea I have for you as it's interesting challenge. Remove some of those other lines and go back to basics ensuring these lines are present:

cpuid.inhibitDarwinMasks = "TRUE"
cpuid.1.eax = "0000:0000:0000:0001:0000:0110:0111:0001"
cpuid.1.ebx = "0000:0010:0000:0001:0000:1000:0000:0000"
cpuid.7.ebx = "----:----:----:----:----:----:--1-:----"
vhv.enable = "FALSE"
vpmc.enable = "FALSE"
vvtd.enable = "FALSE"

and remove:

cpuid.brandstring = "Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz"
board-id.reflectHost = "FALSE"
board-id = "Mac-937A206F2EE63C01"

Check if AVX2 now is present in guest.

No, unfortunately I don't know if this software using FMA\AVX or not, and if yes - what version of it. So my idea was to get it from it's processing speed with different cpu features enabled\disabled.
Regarding cpuid, without any line of these I'm getting an error "CPU was disabled":

cpuid.0.ebx = "0111:0101:0110:1110:0110:0101:0100:0111"
cpuid.0.ecx = "0110:1100:0110:0101:0111:0100:0110:1110"
cpuid.0.edx = "0100:1001:0110:0101:0110:1110:0110:1001"

And without these zeroes in these lines it hangs right after showing apple logo.

cpuid.1.ecx = "----:00--:----:----:----:----:----:----"
cpuid.1.edx = "---0:----:----:----:----:----:----:----"

So the only line that can be removed is cpuid.0.eax = "0000:0000:0000:0000:0000:0000:0000:1011", and nothing is changed in cpu features after doing it.

OK well my mistake there with those settings. I assume you have the latest build of unlocker? If so I suggest the following on the host computer.

Look for the \unlocker\cpuid\windows folder in the extracted unlocker files
Open a command prompt in the windows folder
Run this command:

cpuid.exe -d -c 0

Capture the output and add to the issue, preferable as a file.

I can generate a complete VMware cpuid mask from it.

There is also a macOS version in the cpuid folder. You could also run that in terminal on macOS. It would give a dump of all cpuid values.

Well, it was the latest till yesterday :) Downloaded new version just now.

Output from the windows host is attached, but I was not able to run it in the macos guest :( I have almost no experience in macos, so probably I'm doing something wrong. If I'm trying to launch it from terminal, I'm getting following error:

Attached is a cpuid dump in VMware VMX format. Please don't copy it all in as definitely won't work but we can extract bits of the host CPU and paste into VMX file.

Let's try this where I have added all the host leaf 7 bits:

cpuid.7.0.edx        = "0001:0000:0000:0000:0000:0000:0001:0000"

cpuid on macOS may be failing as we have some Frankenstein's monster of a hybrid CPU. So can use sysctl to get bits as you did previously.

Sorry but I’m out of ideas. I can’t think of anything else to try. I have used my real MacBook Pro and Fusion and can mask AVX2 on and off. Guess it’s something in VMware hypervisor on Windows stopping it. There used to be a setting to force cpuid changes but it was removed several releases ago.

I tried to launch Win 11 vm in the same VMware Player, and cpuid in the guest Windows shows leaf 7 almost identical to the host.
So it seems to me that VMware has some more countermeasures against launching MacOS from non-Apple computers, or just something not implemented. But this is only my speculations.

Pretty sure it’s the second option. It’s probably something that is never tested as not a supported setup. The guest does run just not exposing same features as on real Mac. It’s running on Windows with an AMD CPU, not something that would be on the radar for development and testing.

I’ve got one last thought but I need to go find it. A VMware engineer told me about another VMX setting, but I’ll need to find it. He left VMware and I think the conversation was about 10 years ago, so will need to trawl through my notes to try and find it.

I found the forum thread and tested the settings but it does not work and looks like the code to disable feature compatibility has been removed.

The admin user is the guy who left and his posts were moved to the admin user.

Well.. At least we tried. It is sad that all AVX and FMA stuff is not available to my guest, but anyway it works fast enough on 16 cores.
Thank you for your willingness to help!

It was interesting to see what was going on, but it's sad we didn't get a good result. Good luck with your VM.
