Hey!! I downloaded the mac version on my Early 2015 MacBook Pro with Mojave 10.14.1 It showed that the disk was damaged and did not open up....
Hello!
The game seems to have problems running on the 2015 MacBook Pros. I'm not exactly sure what the cause is but you can try downloading it with another browser or updating your OS (but you are updated to Mojave so this is for all the other people with this problem).
If you haven't yet, you can also try typing this in your terminal:
sudo spctl --master-disable
What this does is allows apps downloaded from anywhere, as this option was removed from the security and privacy settings a while back.
Hope this helps!
