We could add another hackВ to hide kexts inВ kextstat, and that makes itВ even worse. Running kextstat does shows all loaded kexts, so itвЂ™s not that hidden, but cleaner anyway. This way unsigned kexts wonвЂ™t show up in System Information/Software/Extensions, which in my view makes it somewhat harder to detect. I use /Extra/Extensions for unsigned kexts, so that the /Library/Extensions and /System/Library/Extensions directories can be kept vanilla/untouched.

This means that I run my hack with maximum System Integrity Protection (SIP) activated (no rootless=0 boot argument/runtime/NVRAM variables to bypass the code signing restrictions) with the following unsigned kexts: This time I did it differently, and this blog post is a short and simple POC (proof of concept) to show you that bypassing AppleвЂ™s rather strict kext signing restrictions still works. I have found a very simple way to bypass AppleвЂ™s kext signing in El Capitan, like I did before in Yosemite and Mavericks before that.
