Since you are using OpenCore, and if you compile the latest git, it makes future X99 patches obsolete now.
Also a word of advice, do not use the bootstrap or the cpuid set info as well as AppleXcpmExtraMsrs. All you need is the Cpuid1Data and Cpuid1Mask set followed by my patches with your...
Well it requires a program like Hopper Disassembler to achieve it. Back when Catalina first came out, the patches posted by nmano didn't work for me, so I started digging in on how the other patches were done in Mojave by comparing them, then I figured the way they were done and needed on how to...
Here are the kernel patches I did for the update.

Just a FYI for x99/Xeon owners, new kernel kext patches are needed. I will try to get those done here when i get some time.
The ones that need to be patched are:
@skroutz999 I might be able to help you get your system stable. Do a DSDT dump in clover(press F4), do an IOReg save, place it in your EFI partition's EFI folder. Remove your Serials from your config.plist, compress the EFI folder and post it. But looking at what you have done so far, I can see...
There is nothing really different you need to do with the i9-9900K as you would with an i9-7900X. Board recommendations is a personal thing in a way, but Asus, Asrock and Gigabyte are ones that comes to mind. Any NVME device can work with MacOS, although, it may require a little Kext to patch to...
@grootbatavia updating the microcode is needed and can be done easily with Asrock. I highly doubt usb3 was causing your installation issues, as I have no problems with USB3 and USB3 device. Which leads me to believe your clover setup was not correct based on your hardware and/or uefi configuration.
