Hey guys, I’m on the business trip and nowhere near a computer can any of you check if the cpu_max_limit of 64 cores is still there in the kernel?

Well, kext injection usually breaks with major OS versions. Mojave was pretty quick to get up and running last year. Hopefully it won't take long to fix Catalina.

EDIT: Please see https://sourceforge.net/p/cloverefiboot/code/4938/


Looks like the logic has slightly been changed, please try this kernel patch (temporarily) with Clover KernelToPatch:



00 85 C0 0F 84 87 00 00 00 49



00 85 C0 90 90 90 90 90 90 49


Hopefully Clover kext injection works after patching, if it does, I will update the source.
