Full Screen on Mac version

I'm running this game on an Intel MacBook and it refuses to go full-screen even though it claims to be in full screen mode. It's definitely windowed. I tried selecting "windowed mode" in the hopes that clicking back to full screen mode would remind it what full screen should look like. Get this: it won't let me select windowed mode because my "desktop resolution needs to be greater than 1024x768." My resolution is 1280x800.
To summarize: Hidden Relics runs in windowed mode while reporting to be in full screen mode and believes my desktop resolution is lower than it actually is.
Not cool.
Help?
