DriverKit

[1over137]

I fear this will mean kexts (kernel extensions) will be impossible in the near future, further limiting users' abilities and tightening Apple's control. :(

> In #SOTU, Apple just announced that "in a future #macOS release", KEXTs targeting driver categories covered by #DriverKit will no longer work and encouraged developers to adopt #DriverKit now. #WWDC19

Is this the long march toward making Hackintoshes impossible?

Looks like https://en.wikipedia.org/wiki/User-Mode_Driver_Framework, but for mac.

A nice nod to NEXTSTEP :) (in name, and I suppose somewhat in the original and largely unrealized microkernel philosophy of having more things in user space)

Yep, here is the NeXTSTEP documentation for DriverKit.

Could this be used for better nvidia egpu drivers?

Apple doesn't release anything to allow 3rd party development of drivers that integrate into accelerated pipeline (afaik you can do basic frame buffers but that's it).

nVidia coasted on having been used in some of the mac hardware thus having access to at least some versions of the APIs, but it seems that what they have no longer works with Mojave.
