So on the shortcut for rotations the ctrl + arrow keys should do a small rotation. However this doesn't seem to work on my Mac. It just switches between my actual screen and my shortcut screen (time, weather, stocks). Does anyone know how to turn this off? It really is a burden to have to right click and go to the small rotation every time.

Thanks

Somewhere in the settings there is a hot key option which you can change from control and arrow

I think small rotations use the option key

Im still running snow leopard and afk atm, but I think the setting you're looking for is in the Workspaces group (or whatever its called, i never really use it), at the top row of the preferances window. You'll have to change the hotkey in oxs, you cant change any of the vassal hotkeys.
