Mach 3.0 Kernel AND FreeBSD kernel (portions) 4.8 BSD

It has been mentioned OS X doesn't use procfs UNVERIFIED
------------THIS May indicate Heavy Lifting required when bug hunting -----
-------------------------Very cross-port implemented-----------------
Mac OS X provides a robust set of optimized libraries, making it easy to
port your existing UNIX code. For example, a standard, multithreaded C
library (libc) includes support for such capabilities as reentrant
variants of standard functions (such as strtok_r), facilitating the
porting of thread-aware applications to Mac OS X. For applications that
require non-Roman character sets, Mac OS X supports wide character
datatypes (wchar_t and others). Panther also supports UNIX/Linux
portability APIs, including System V semaphores, so porting applications
from versions of UNIX such as Linux and Solaris presents no problem.

*Don't let its elegant and easy-to-use interface fool you. Beneath the
surface of Mac OS X lies an industrial-strength UNIX foundation hard at
work to ensure that your computing experience remains free of system
crashes and compromised performance. With its advanced virtual memory,
you don't have to concern yourself over the number of applications you
have open -- just continue working. If an application should ever crash,
the system's memory protection prevents it from taking the rest of the
system down with it. And the time-tested security protocols in Mac OS X
keep your Mac out of harm's way. *
The most widely-distributed UNIX-based operating system, Mac OS X offers
a unique combination of technical elements to the discerning geek, such
as the fine-grained multithreading of the Mach 3.0 kernel, tight
hardware integration and SMP-safe drivers, as well as zero configuration
networking. Panther integrates features from state-of-the-art FreeBSD 5
into Darwin -- the Open Source <http://www.apple.com/opensource/>,
UNIX-based foundation of Mac OS X -- to provide enhanced performance,
compatibility and usability.

*Command-line environment*
UNIX users will feel at home in Darwin, the robust UNIX-based
environment that underlies Mac OS X. That environment is accessible at
any time from the Terminal application. You can also run commands that
don't require arguments (such as top) by double-clicking them in the
Finder. With the thousands of man pages included in Mac OS X, you can
quickly find all your favorite UNIX tools.
*UNIX utilities and scripting languages*
All of the standard UNIX utilities and scripting languages are included
in Mac OS X: editors such as emacs, vim and pico; file management tools
such as cp, mv, ls and gnutar; shell scripts including bash (the default
shell), tcsh (csh) and zsh; and scripting languages such as Perl, PHP,
tcl, Ruby and Python. Python users can also script the powerful Quartz
<http://www.apple.com/macosx/features/quartz/> compositing engine. Learn

technology brief. And visit our Open Source
<http://www.apple.com/opensource/> page for a list of Open Source
utilities in Mac OS X.
*Universal libraries*
Mac OS X provides a robust set of optimized libraries, making it easy
to port your existing UNIX code. For example, a standard, multithreaded
C library (libc) includes support for such capabilities as reentrant
variants of standard functions (such as strtok_r), facilitating the
porting of thread-aware applications to Mac OS X. For applications that
require non-Roman character sets, Mac OS X supports wide character
datatypes (wchar_t and others). Panther also supports UNIX/Linux
portability APIs, including System V semaphores, so porting applications
from versions of UNIX such as Linux and Solaris presents no problem.
*Kernel*
A key factor in the stability of the system is its advanced memory
protection and management system, which ensure reliability by allocating
a unique address space for each application or process. The Mach kernel
augments standard virtual memory semantics with the abstraction of
memory objects. This enables Mac OS X to manage separate application
environments simultaneously and supply the following features:
Preemptive and cooperative multitasking.
Symmetric multiprocessing (SMP) augmented by support for multithreading.
Real-time support guaranteeing low-latency access to processor
resources for time-sensitive media applications.
