So you are an unwealthy programming hobbiest who cannot afford the
exorbitant fees of becoming a full blown Apple Developer Connection
Member complete with access to pre-release seeds of the forth-coming
OS, and you also don't like the idea of stealing pre-releases off of
the underground internet and risking legal persecution from Apple.
Nevertheless, you have an OS X product that you are proud of and would
like to continue to support for years to come. What do you
do? Get yourself a blog and harness the power of good people and
the internet to help you reverse engineer OS X. That's what Rich
Wareham, the coder behind Desktop Manager, did. If you're interested in doing the same, you should read his tutorial.
This type of news is why I love OS X. It's about the community working together.
