@caniggia, could you please check this clover version?
I'm curious if it works with an original DSDT (dropping the patched file at boot time) and CPU->PatchAPIC option enabled.
A preboot.log would be nice
It shouldn't boot completely, but to step over x86_validate_topology().
Wow, thank you for the findings. We had to match the IDs from DSDT with APIC. :banghead:
Here is an easy way to create a Clover hot patch to resolve this:
Your patch should be something like this: C000(80)>C000(00)

The method found for X299 (editing APIC instead of DSDT) should...
Your preboot.log shows that you started Windows instead of macOS, so most of logs are not present.
The root cause seems to be similar (LocalApicID 0 is not active), but at the same time ProcessorID already start from 0, so it may need a different solution.
You may try to patch your APIC table so...
From the logs, these 10 cores Skylake-X 9xx0X CPUs are 14 cores CPUs with 4 defective/disabled cores. I suspect that there are issues with the CPUs where the first core (#0) is defective. This may explain why only some 9900x works. The 8/ 14/ 18 cores CPUs have all cores active, nothing...
@ori69, can you please run the following commands in Linux (works also from Live CD) and attach the output ?
$ cat /proc/cpuinfo
$ cpuid
1. Save the complete output, even if it seems to be repetitive
2. cpuid probably needs to be installed first: eg: apt install cpuid
Can someone do the same...
