So what does this mean for C4D on OSX? Metal is nor openSource nor crossplatform. I think this is bad news for C4D, but maybe I’m just wrong.
Deprecation of OpenGL and OpenCL Apps built using OpenGL and OpenCL will continue to run in macOS 10.14, but these legacy technologies are deprecated in
macOS 10.14. Games and graphics-intensive apps that use OpenGL should
now adopt Metal. Similarly, apps that use OpenCL for computational tasks
should now adopt Metal and Metal Performance Shaders.
