I have some bad news, I did some looking around and it looks like your gfx card doesn’t support metal. There’s no toggle I can find in-game to switch from metal to openGL (which is what your card supports).
You may have some luck launching through the terminal. Take a look at this thread, and let me know if you need help navigating the terminal or anything: Unable to open after new patch on mac - #2 by Unitil-1295
Edit: I tried launching with openGL support on my mac, and didn’t have any luck (though I have a gfx card which does support metal, it also supports OpenGL). You may want to look for a refund.
