What is the purpose of bootstrap server in Mach?

Is OSX monolithic?
While the macOS kernel combines the capabilities of a microkernel with Mach and a monolithic kernel like BSD, Linux is just a monolithic kernel. A monolithic kernel is responsible for managing CPU, memory, inter-process communication, device drivers, file system, and system service calls.

Is OSX still UNIX?
Yes, OS X is UNIX. Apple has submitted OS X for certification (and received it,) every version since 10.5. However, versions prior to 10.5 (as with many ‘UNIX-like’ OSes such as many distributions of Linux,) could probably have passed certification had they applied for it.
