Not sure if anyone at MacRumors heard about this but the makers of FL Studio have released a beta test version of the audio creation software for Mac OSX. It's still the PC version simply Crossover wrapped but if Mac users show interest they may go ahead with a native OSX version in the future.

They do state that this is simply a test demo to see if there is interest and the final version built for OSX may not actually happen so no support is offered for this version beyond setting it up. All plugins are up to the user to try but there are no guarantee they will work in OSX.
