Why can’t I admit that. BSD is a fine alternative to MAC. In fact, it makes a lot of sense if you are MAC user looking for alternatives.
Oh I see...you think I live on this board and respond as soon someone posts something. Silly you...I have a life.
With a rock-solid UNIX foundation and powerful technologies such as Grand Central Dispatch, OpenCL, Bonjour networking, and built-in synchronization, Snow Leopard unleashes the full power of your Mac.
UNIX: A robust, proven foundation.
UNIX is widely known for its robust, proven foundation that’s scalable, powerful, and crash resistant. And with tens of millions of users — consumers, scientists, animators, developers, system administrators, and more — Mac OS X is the most widely used UNIX desktop operating system in the world.1 It offers a unique combination of technical elements, such as fine-grained multithreading, FreeBSD services, and zero-configuration networking. Its state-of-the-art kernel supports preemptive multitasking, symmetric multiprocessing (SMP) scalability, and 64-bit virtual memory, while standards-based access control lists take UNIX permissions to the next level.
UNIX power users will feel at home in Darwin, the robust BSD environment that underlies Mac OS X and is accessible from the Terminal application. All of the common UNIX utilities, command shells, and scripting languages are included in Mac OS X, including Perl, PHP, tcl, Ruby, and Python. And Mac OS X provides a set of optimized libraries, making it easy to port your existing UNIX code.
From Wikipedia:. . . so OS X partakes of BSD Unix. That's all I meant.Mac OS X is based upon the Mach kernel.[9] Certain parts from FreeBSD's and NetBSD's implementation of Unix were incorporated in Nextstep, the core of Mac OS X.
