Kernel extension is not being installed.

[Threesocks]

Need to use legacy drivers for clamshell mode, so them not loading is a problem.
What I see under extensions is that it can't load because of dependancy errors:

No kexts found for these libraries: com.apple.kernel.mach, com.apple.kernel.libkern, com.apple.kernel.iokit

I'm trying to use 5.2.5 and I suspect in my case that ARM architecture is the problem.
