like I can get it and everything but when its open it says its open on the top panel bit, but its still my desktop
I just checked the terminal for it and it shows
[0131/231002.880608:WARNING:system_snapshot_mac.cc(42)] sysctlbyname kern.nx: No such file or directory (2)
Have you tried redownloading it, opening the folder and moving ONLY the "game" file into your applications folder? I think you still have to override the security to open it but it should work fine after that
