Can’t open game

I know it is a good game, but I can’t play it on my macbook pro 2015 with OS X 10.10.5. After I downloaded the game and clicked the shortcut, a window occurred showing some pre-settings. Then I clicked play and there was nothing showing except my desktop. Anyway I can’t enter the game, so some bugs need be fixed. I hope the upates can be released quickly.
