I don't know how this differs with installing Hackintosh on real hardware, but then you provide a kernel extension (kext) called FakeSMC, which emulates the SMC chip present on real Apple computers. So in a sense, he is not using an actual SMC key, but very probably replaced it by FakeSMC. You can see that it is actually included in the repo he clones: https://github.com/SRH1605/Hackintosh-KVM/tree/master/kexts/Other https://github.com/SRH1605/Hackintosh-KVM/tree/master/kexts/...
