I made a game in high school and I tried moving the files for the game over to my MacBook Pro. I downloaded the Mac version of Greenfoot and I copy and pasted all of the code into Greenfoot and titled it accordingly. I compile everything and I have "no errors" however the game will simply not load up on the screen. I do have music for the game and it is also not working. However, I do have the same music downloaded onto my computer.
