"Deploying a kext requires it be signed using a special Kernel Extension Signing Certificate, which can only be acquired from Apple. Getting one of these certs requires going through a fairly rigorous application process. And of course, at the end of it all, you can be denied with no real recourse. Basically, your project lives and dies at the will of Apple–a markedly different approach from what you’re used to if you’re used to the Linux and Windows approaches to third-party kernel modules." ugh, I hate this sort of thing
