Key checker for mac? .jar perhaps?

Hey I was just wondering if it's possible to make a key checker that can be used on a mac? Often i get a key on my mac and dont want to turn my pc on to check it. Would it be possible to somehow convert Darky's into a mac compatible one?

thanks

Your best bet would be to get rid of a mac OS, I haven't heard of a CD changer for mac though.
