Anyone who actually wants to run this game in Mac OS X 10.6.8 can try this little trick:
- Download Mac OS X App Bundle from download section
- Right click on game icon and choose: "show package contents".
- Open "Contents" folder.
- Right click on "Info.plist" file and choose Open with... then select "TextEdit".
- Find text "<key>LSMinimumSystemVersion</key>" and change information below it - from "<string>10.7</string>" to "<string>10.6</string>".
- Close editor and SAVE changes.
From now game should work in but I cannot guarantee the stability (and proper working) of the game and/or operating system. This trick works for me (I've tried to install the game using homebrew but I had problems so I looked for other options). Good luck
