To recap: the underlying MacOSX operating system is Mach 4.4, which is bsd based, and (believe it or not) does *not* use the Mach microkernel. Ask Avie Tevanian if you have to. Mach ideas, microkernel ideas, but not the Mach microkernel.
You're not right, I think you've got to read the documentation that come from Apple developper website about the kernel, http://developer.apple.com/techpubs/macosx/Syste m/Documentation/Developer/Kernel/KernelEnv ironment.pdf The MacOSX operating system is based on the MACH 3.0 microkernel, which is compatible with BSD 4.4. Maybe you should check the source code of the Darwin projkect to be convinced?
