Arduino Lightsaber

I've come to a new hurdle in my saber smithing adventure. While researching components, I realized that to upload the audio files to the wt588 you need pc software while I am on a mac. Yes, I could use some virtualization, but I was hoping for a more native or cross platform solution and I don't want to buy software for a one time use. Are there any mac compatible sound modules out there that would work like the wt588?
