 Security focused operating system - Wikipedia, the free encyclopedia
OpenBSD is an open source BSD operating system that is known to be concerned heavily with security.
All derived BSD operating systems are all released under the terms of a BSD licence.
In addition, some operating systems meet certain evaluation criteria: they can be described as security-evaluated operating systems; but this as such does not make them secure.

 Mac OS X Basics -- System Architecture: Darwin
Darwin is the UNIX-based industrial-strength core foundation of Mac OS X. Its Open Source architecture allows developers to collaborate with Apple Engineers, create applications, and customize OS X with greater ease than with previous Mac operating systems.
The open source design also gives end-users all of the benefits of a faster and more reliable operating system.
Darwin is comprised of two notable components: Mach 3.0 and BSD 4.4.

But yes, if you took any operating system and put it in the most popular ones place, you would find that tons more people would be working out ways to break it, create holes, and find holes.
See what you are failing to recognize, is that they took a singular computer with each operating system and attacked it.
BSD is jsut as prevalent as windows in places where security matters, whereas most linux security breaches are redhat/fedora servers rented by your average joe that thinks he knows alot from datacentres, and thus are easilly penetrated.

 Coherent (operating system) - Wikipedia, the free encyclopedia
The Coherent operating system was introduced in 1983 by the now-defunct Mark Williams Company as one of the first Unix-like systems for IBM PC-compatible computers.
Much of the operating system was written by ex-students from the University of Waterloo: Tom Duff, Dave Conroy, Randall Howard, and Johann George.
Coherent was based on the specifications of Unix Version 7, without reference to any of the Unix source code, either from Bell Labs or BSD.

 Outpost.com Apple OS X Showcase
At the core of Darwin is a key component called the kernel, the pivotal component in the operating system that handles most of the interaction between the operating system and the hardware.
The system's kernel is based on Mach 3.0 from Carnegie-Mellon University and FreeBSD 3.2 (derived from the University of California at Berkeley's BSD 4.4-Lite), the most highly regarded core technologies from two of the most widely acclaimed OS projects of the modern era.
The effort paid off big time: Darwin delivers the reliability and performance you'd expect from a modern operating system, ensuring users and developers the benefit of a high-quality, interoperable system built on open standards.

 Chapter 1. Introduction
Darwin is an advanced BSD UNIX operating system for PowerPC and x86 compatible architectures, currently owned and developed by Apple Computer, Inc. It forms the core of Apple's flagship Mac OS X operating system, which has been catapulted from its release in 2001 to being the most widely distributed UNIX-based operating system.
There are those coming from OS X looking to learn more about the core of their operating system and find out why things work as they do, look at source to help them better understand what's going on under the hood so they can improve their products, and so on.
OpenDarwin is an operating system based on Apple's Darwin, but with certain "value added" features.

 Distributed Operating Systems (Sprite and Ameoba)
The goals of these systems to allow transparent sharing of resources is the same as that of the distributed operating systems of the 80's, except the systems being built now are build on top of operating systems instead of inside them.
Sprite is 4.3 BSD compliant with some extra features: sprite adds the ability to fork jobs on idle machines, does automatic process migration (including forwarding when necessary), and includes a single, completely transparent file system.
In Sprite, although the kernals communicate with RPC, the RPC mechanism is hidden from the applications which have to communicate through the file system.
