Emmanuel Dreyfus recently noted that progress has been made with NetBSD [1]'s Mach [2] and Darwin [3] binary compatibility layer. Specifically, "WindowServer is able to talk with mach_init and it runs for quite a long time before crashing. Next steps are to fix the emulation bugs that cause WindowServer to crash, and then to re-implement enough of Darwin's IOKit to get WindowServer actually displaying something." (WindowServer being MacOS X's equivalent of an X server.)

According to the project's home page [4], "Once we will have a fully functionnal Darwin binary compatibility on NetBSD/powerpc (if that happens some day), we will just have to grab MacOS X libraries to run any MacOS X program, just like NetBSD is now able to run binaries from Linux, FreeBSD, Solaris, and many other OSes." Learn more about binary emulation with NetBSD here [5].

Hi folks

One step forward on the road to MacOS X emulation: WindowServer (The
MacoS X equivalent of the X server) is now able to talk with mach_init,
which works as a name server for Mach tasks. it crashes later, but at
least we are getting some Mach IPC working.

To avoid copy/pasting the information each time, I made a status page on
the web with some FAQ and their answers

And the usual message: this subproject is bottomless. Feel free to help.
