Mac OSX uses the Mach microkernel at its core, but the BSD subsystem also sits in kernel space to take care of things like I/O. So it is not a pure microkernel operating system. Windows is actually similar - the NT operating system has a microkernel at the centre, but then just about everything else is also thrown into kernel space with it.

So I guess they have an elegant design at first, then hack it to make it actually perform good.
