Mac OS X and the Power of UNIX
Beneath the appealing, easy-to-use
interface of Mac OS X, you'll find an industrial-strength,
UNIX-based foundation called Darwin.
This open source
core of Mac OS X is highly stable and built on mature technology:
|
|
- A Mach 3.0 kernel with support for symmetric multiprocessing.
- Based on 4.4BSD with networking from FreeBSD 3.2.
- Support for most POSIX APIs.
- Popular development tools such as gcc, gdb, vi, emacs, pico,
Perl, etc.
- Popular UNIX shell tools such as grep, chmod, ps, crontab,
top, tail, etc.
In addition, Darwin provides an object-oriented
device driver framework called I/O Kit which supports true plug-and-play
and power management. I/O Kit also provides abstracts of most common
device classes including USB, FireWire, Audio, Network, PCI, and
more.
Darwin also offers an advanced stackable file system, including
support for UFS, ISO 9660, FAT, NFS, WebDAV, UDF, and more.
Free Development Tools
Apple provides developers with a complete integrated
development environment (IDE) for Mac OS X. To download your copy
of Mac OS X Development Tools, become a free

Member of the Apple Developer Connection.
Great
Extras
In addition to basic UNIX
goodies like network client tools and system services, Mac OS X
offers developers easy access to an array of advanced technologies:
- Quartz Extreme - Mac OS X's new 2D
drawing API is based on the Postscript/PDF drawing model and
provides full support for transparency and anti-aliasing, multiple
color spaces, import and export of PDF, plus built-in ICC color
management.
- OpenGL - Mac OS X supports
the industry standard OpenGL 3D graphics architecture accelerated
by nVidia and ATI graphics adaptors.
- QuickTime - Through Mac
OS X, developers can access QuickTime's complete multimedia
architecture including Flash 4 Support, Cubic VR, RTP/RTSP video
streaming, MPEG support, and more.
- Unicode - Developers can localize
their applications into double byte languages quickly and easily
using Mac OS X's support for Unicode.
- CUPS - The Common UNIX Printing System ("CUPS") is a cross-platform Open Source printing solution for UNIX environments, and will be used as a portable printing layer for Darwin and Mac OS X. CUPS is based on the Internet Printing Protocol and provides both System V and BSD command-line printing services for PostScript and raster printers.
User Experience
Several
implementations of the X Window System are available for Mac OS
X including Tenon's
Xtools, XFree86, and
others. But to provide users with the Mac OS X Aqua
user experience and gain access to advanced Quartz graphics
libraries and other Mac OS X APIs, UNIX developers can factor an
application to keep its core logic intact and use Cocoa's
rapid application development frameworks to build a native Mac
OS X interface. |

OpenOffice 1.0 (X11) is Final Beta for Mac OS X
Today, OpenOffice.org and the OpenOffice.org Mac OS X/Darwin porting team announces the release of OpenOffice.org 1.0 X11 for Mac OS X and Darwin (Final Beta). While this release is not final and is intended to solicit public feedback, bug reports, and to attract developers to the project, it is feature-complete for our first X11 (Final) release. The main focus will be on fixing bugs in the Final Beta to allow for a full Final release in Spring 2003.[Jan 08 2003] |
X11 for Mac OS X Public Beta
X11 for Mac OS X offers a complete X Window System implementation for running X11-based applications on Mac OS X. Based on the de facto-standard for X11, the open source XFree86 project, X11 for Mac OS X is compatible, fast and fully integrated with Mac OS X. It includes the full X11R6.6 technology including a window server, libraries and basic utilities such as xterm. Other X11 toolkits (e.g., openMotif, gtk) are available from OpenDarwin.org[Jan 07 2003] |
New Web Rendering Frameworks
Apple is releasing the source code to two new frameworks underlying its new Safari web browser. Both are based on code derived from the KDE project - WebCore from KHTML and JavaScriptCore from kjs. Apple is releasing our enhancements as well as Objective-C++ wrappers which make them easy to integrate into Cocoa applications.[Jan 07 2003] |
DarwinPorts now supports user packages
DarwinPorts is a BSD licensed software build, install, and packaging infrastructure conceived as a part of the OpenDarwin Project. Written almost entirely in TCL, DarwinPorts is designed to be easily extended, embedded in other applications, and ported to a wide variety of architectures. DarwinPorts is in active development and currently supported on Mac OS X 10.2 and Darwin 6.0.2.[Jan 07 2003] |

MySQL on Mac OS X
MySQL on Mac OS X is fast, stable, straightforward to learn. Not as complicated as some databases, it is nevertheless robust enough for the vast majority of web development applications -- which is probably why it has become one of the most widely used open source databases available. This article outlines the many benefits (and few drawbacks) of MySQL, and most importantly, provides detailed instructions on how to securely install it on Max OS X. |
Installing
Perl 5.8 on Jaguar
Want the latest version of Perl to go with the latest version of
Mac OS X? Follow these step-by-step instructions to install Perl
5.8.0 on Mac OS X v10.2. Naturally, we include instructions on how
to get CPAN up and running as well. |

Porting Guide (pdf)
The UNIX Porting Guide provides an overview of what you need to
do to bring an application from a UNIX platform to Mac OS X. It
provides descriptions of many of the technologies present on Mac
OS X that may be unfamiliar to UNIX application programmers. |

Fink
0.5.0a
The Fink project wants
to bring the full world of Unix Open Source software to Darwin and
Mac OS X. We modify Unix software so that it compiles and runs on
Mac OS X (port it) and make it available for download as a coherent
distribution. Fink uses Debian tools like dpkg and apt-get to provide
powerful binary package management, and includes ports for everything
from X11 to python to gimp. |
Webmin
1.050
Webmin is a web-based
interface for system administration for Unix. Using any browser
that supports tables and forms (and Java for the File Manager module),
you can setup user accounts, Apache, DNS, file sharing and so on.

Porting
UNIX-based software to Mac OS X Mailing List
If you're trying to port software to Mac OS X from UNIX, Linux,
or BSD, then this is the list for you. This list is for community
discussions regarding all the questions people face when doing a
port: What's different about Darwin? Which high-level toolkits should
I use for my GUI? Is there a workaround for this problem? Has someone
tried to port this before? |
XFree86
4.2.0-1.1.0
XFree86, a freely
redistributable open-source implementation of the X Window System
that runs on UNIX(R) and UNIX-like (like Linux, the BSDs, Mac OS
X (aka Darwin) and Solaris x86 series) operatingsystems and OS/2.
XFree86 is the underlying software that is between the hardware
and graphical user interface (aka gui) that people see and use.
If you are using KDE, GNOME, Enlightenment, Blackbox, AfterStep,
twm or fvwm then you are already using and running XFree86 as these
run as our clients. |

TweakWaves
The TweakWaves 1.0 sample application
is being distributed "as is". It's solely intended to show the capabilities
of Tweak Films' water simulation capabilities, the ease of porting
UNIX applications to Mac OS X and the powerful graphics capabilities
of the Macintosh, especially the nVidia GeForce line of products.
