The software player for Prime Ordinals (Jim Casella) was created in 2009 and may not work on more modern Mac computers. If you encounter this problem with the app found in the "MAC" folder, there's a pretty easy workaround.
- Download and install the latest version of Max at cycling74.com.
- Launch Max on your computer.
- Open the Prime Ordinals.mxf file (found within the "Prime Ordinals PC" folder). You can do this by either dragging the file onto the Max icon in the doc of your Mac, or by choosing Open from the File menu, then navigating to the file.
Once the player is launched within Max, all functions of the player should work as outlined in the instructions.
