Can someone explain? Is there something other than DriverKit, which seems to be C++?

You have to go back to IO Kit, Driver Kit is the new one in userspace.

Which is how the Objective-C framework for NeXTSTEP drivers used to be called,

I suspect they’re either conflating things with ObjectiveC or FireBloom (https://saaramar.github.io/iBoot_firebloom/)

Both would sort of fit those descriptions I guess if one were to squint.



Oh interesting. Thanks for the link
