Where to Go for More Information

Although this book will get you started with the Unix underpinnings of Mac OS X, there are many online resources that can help you get a better understanding of Unix for Mac OS X:

Apple's Open Source Mailing Lists

This site leads to all the Apple-hosted Darwin mailing lists, and includes links to list archives.

The Darwin Project

Darwin is a complete Unix operating system for x 86 and PowerPC processors. Mac OS X is based on the Darwin project. Spend some time at http://developer.apple.com/darwin/ to peek as deep under Mac OS X's hood as is possible.

Open Darwin

The Open Darwin project was founded in 2002 by Apple Computer and the Internet Software Consortium, Inc. (ISC). It is an independent project with a CVS repository that is separate from Apple's Darwin project, but it aims for full binary compatibility with Mac OS X.

Fink

Fink is a collection of open source Unix software that has been ported to Mac OS X. It is based on the Debian package management system, and includes utilities to easily mix precompiled binaries and software built from source. Fink also includes complete GNOME and KDE desktop distributions.

DarwinPorts

DarwinPorts is a project of OpenDarwin that provides a unified porting system for Darwin, Mac OS X, FreeBSD, and Linux. At the time of this writing, it includes several hundred applications, including the GNOME desktop system.

GNU-Darwin

Like Fink, GNU-Darwin brings many free Unix applications to Darwin and Mac OS X. GNU-Darwin uses the FreeBSD ports system, which automates source code and patch distribution, as well as compilation, installation, and resolution of dependencies.

Mac OS X Hints

Mac OS X Hints presents a collection of reader- contributed tips, along with commentary from people who have tried the tips. It includes an extensive array of Unix tips.

Stepwise

Before Mac OS X, Stepwise was the definitive destination for OpenStep and WebObjects programmers. Now Stepwise provides news, articles, and tutorials for Cocoa and WebObjects programmers.

VersionTracker

VersionTracker keeps track of software releases for Mac OS X and other operating systems.

MacUpdate

MacUpdate also tracks software releases for Mac OS X.
