You literally cannot run the programs neccessary to make levels or ganis with a Mac, I've looked, all solutions were complex, unnecessary, and in some cases expensive programs, there is not way to just convert programs, and even if I could, who knows how that would limit or cause problems with the programs with uploading and saving and setting tilesets and stuff, And quite frankly, its more of Stefan's fault for not making a version that both Mac and windows can use or a seperate Mac version, not my fault that I am one of the many people that bought a Mac.
