I have that in my 'graphicsConfig.ini' in Eldevin game directory, which is on Software rendering, I don't know how software rendering goes for Macs but it works perfectly in Windows .
If you can find the Eldevin game directory in Mac, you might find some file like 'graphicsConfig' open it like a text and change Renderer into 'hardware_newt' or 'hardware'.
