Hey I’m having the same problem if any one can help it would be great

I saw a lot of people say that you can just download MacOS HighSierra but this did not work for me. I dont know why but after I installed the MacOS HighSierra the game still said that I did not have the graphics card or am running on MacOSX 10.11.6.

I get the same error message on my iMac with the same specs. Updating to the latest OS X did not help.

It’s metal if only people know how to get it then problem solved.

i am getting the same message even tho i have a version of 10.13.3 if anybody knows how to solve this problem plz reply fast i am not buying a whole new graphic card just for one game . i even hope that they fix this problem as soon as possible.

From what I was told by Apple, it basically means your computer is too old and theres nothing you can do.
To get around it I use NVIDIA GeForce Now. Its basically cloud playing. It works fine and they have other games you can play as well.
