I recently re-installed OSX on my mbp … and decided to look into a more integrated approach for my development environment. Since I’m developing in PHP as well as CF, I opted to pickup MAMP, which is a packaged lamp-ish type stack installer and configuration manager for Apache, MySql, and PHP on Mac. There is a free version, but I decided to get Mamp-Pro because I like using virtual hosts, and it’s such a good product that it needs to be supported.
Mike Jones has a great video tutorial for CF8 that helped me get CF9 up and running under MAMP.
