I know that it's not the best practice, however I also use Mac OSX and I use Crossover Mac from Codeweavers to run Windows Application on my Macbook. It's not free, but there is a fully trial version you can use. Anyway, i think that $39.95 for the standard license it's not so much and I can say that it's the best solution at the moment (I was using it for running windows application on linux also)
