so download the game file for apple. once the game is done downloading right click it and choose the open option. It is going to say that you can't open it. ignore that message and close it. right click it again and choose the open option. This time it will ask you if you are sure you want to open it. Click open and then you can open the game normally without right clicking it. It's been sometime since I did it, but I'm pretty sure this is how I did it. Let me know if you have any troubles or any questions.
