Love the game but….

I’ve loved playing this game on my mac since i downloaded it almost a year ago but upon starting it up after updating to OS X 10.9 when I start the game in full screen, the screen gets blurry and all the colors are messed up. Frankly, it looks like Sid Meiers took a bad trip on acid. Is anyone else having this problem? Please help if you can.
