Hey we are sorry that you are having troubles, we are trying to find solutions but it is a bit difficult as none of us own a mac. Can you tell me what sort of hardware you are using? like what graphics card is in your macbook for example? Thanks!
This was a problem for me originally but I managed to get around it by using a different program to unzip the file (Keka instead of the default Archive Utility). I'm so glad I did because it's such a nice relaxing game.
