I've tried drilling down and using OpenGL development tools but Apple is moving away from supporting that graphics engine. I see from reading this forum, DDO works on OSX 10.15 now which OpenGL is deprecated (Apple is pushing "Metal" and x64 code only instead of OpenGL/x32 now) and am now scouring the net for any tricks to get anti-aliasing to work I have a ATI RX570 if that helps.

Good Hunting !
