Can a mac play maple story

No you can't nor can you play it on a Windows 7. The person who gave this answer before me is only half correct. They are correct in the fact you can't play Maple Story on a Mac. Where they are incorrect is that you can't play it on Windows 7. You can indeed play Maple Story on Windows 7 because the laptop I'm using right now has it installed plays and it has Windows 7.
you can play maplestory on windows 7 if you run it in copatability mode. You don't need to use compatibility mode on Windows 7 to play Maple Story. I can take a screen shot right now or a video shot and prove that you do not.
