don't worry everyone eventually he will add a mac version but this mean that he might have to change a few stuff in the games mechanics and engine. Also he may not do it until his game is almost clear of bugs. So I suggest this...
KEEP CLAM AND WAIT.
In the meantime there are other game to be played that can run on mac. But for now just wait until the dev is either finished with the removal of bugs or until he thinks it ready for an OS transfer. The developer is working hard so don't push him to far. I notice a lot of you guys want the mac version so badly but you have to understand that things can't be rushed or else the out come will be bad. Again
KEEP CALM AND WAIT.
