What are the useful UML modeling tools under Mac?

I'm going to be a small community site, and I want to use UML tools to sort out the requirements function.
Using the environment Mac, ready to develop with PHP, what is the better tool to support? Better support for generating some PHP code

The UML Modeling tool under Mac, as far as I can tell, is only visual Paradigm, but it's not. Other large and small tools are basically only drawings, and there is no modeling function.
But then again, no UML tool is not a big deal, the need to comb the needs of the UML, you just need to follow the requirements of scrum to the user store description clearly affixed to the whiteboard, and then let everyone to each need to estimate the development time, run two sprint on everything clear.
Do PHP development, I certainly recommend Phpstorm,osc is playing in the fold, now shot not regret:-D dddd
