Hi! Great news! I just wanted to let you know I finally got the game to work on the mac. Yay! It turns out the first command I was typing was incorrect. Here is what I typed:
cd /applications/Ttc.app/Contents/Macos
chmod +x Ttc
That did the trick. Thank you so much for being patient with me while I was attempting to figure this out. I have only played 1 game so far, but I love it a lot. I tavelled a distance of over 500 feet.
