Apple used to release a small open source OS called Darwin, which was the basis of macOS (xnu kernel + libraries and runtime), without a GUI. With time Apple started to release less and less. A smaller part of the kernel and a smaller part of the runtime. Already a long time ago there was no "Darwin" to speak about, only a barely compilable xnu kernel and some runtimes, sometimes not compilable without additional components only Apple has. This project tries to fill the holes and create an open source OS that uses what Apple still gives us in terms of source code. I don't think it's run by Apple engineers. Actually, seeing the low activity and the fact they are working on old versions of the code, I think there is no real activity to speak about.
