Introducing the Mac Open Source Software Directory

by Derrick Story

Earlier this year, when Jason McIntosh offered to let us integrate his excellent "Mac OS Open Source Software" site into O'Reilly's Mac DevCenter, we felt that it would help us complete our vision of being a complete open-source resource for Mac users. Happily, we've just finished the first stage of this transition, and the directory is now up and running. This incarnation is titled the Mac Open Source Software Directory.

For easy access, you can always find a link to the directory on the home page of the Mac DevCenter. Once you access it, you'll see that the entries are listed in alphabetical order and can be scanned by scrolling down the page. If you are looking for a particular title, you can quickly jump to that section by clicking on the lettered hyperlinks.

Currently we have more than 100 entries that consist of software and projects that are open source and run on the Mac. Many of the entries are for Mac OS 9 and earlier, but more and more open-source software is becoming available for Mac OS X., and we'll be adding these listings as we become aware of new titles.

We have verified all of the current entries, but if you notice a mistake or know any additional information that should be listed, please help us keep the directory accurate by sending us the updated information. And, if you know of Mac software that complies with the GPL, Apple Public Source License, or comparable agreement, please contact us. We want to keep this directory as fresh and up to date as possible.

Send updates and additions to Include the words "Mac Directory" in the subject field. If you have an update to an existing listing, please supply all of the pertinent information and an URL we can use to cross-check the source. For new additions, include title, operating system, license type, and URL.
