I agree with greg252. There are plenty of developers out there running PHP on a mac, and I think having a section for mac users would be a great idea.
stolzyboy, I'm sure there are plenty of mac users who don't feel comfortable with the command line. Chances are, if your on a mac and are having problems integrating PHP, then you'll want specific advice from mac users with a similar version of your OS. I for one, remember jumping through a few hoops with sendmail, MySQL, and PHP. Fortunately there is a great forum over at macosxhints.com where much help can be found for PHP on a Mac.
