OpenGL Issues in OS 10.11.6

[Icify]

I'm trying to play Dungeon Defenders 2 on Steam but upon opening the game I get this message:



I have downloaded XQuartz and typing 'glxinfo | grep "OpenGL version"' gives me 'OpenGL version string: 2.1 INTEL-10.14.73', so what's going on here?

Something I also find strange is that the Direct3D tab in wine regedit at HKEY_CURRENT_USER/Software/Wine is missing - .

Help would really be appreciated.

I should add that I followed the instructions available on the MacOS wiki via the Homebrew line: https://wiki.winehq.org/MacOS/Building

Apologies and thanks again.
