You can not turn off the music and there is no normal way to exit the game on MacBook. I had to hold down F3 and select another screen then exit by right clicking.
Love and Hate kind of thing
Love the game. Old school type of game. HATE Have to unplug iMac to stop the game. YOU CAN PLAY IT OVER AND OVER, BUT I CAN'T GET IT TO STOP!!!!!!!!
