What is gonna happen to games and apps which were using OpenGL since today then? They will stop working in the new macOS version?
edit, ups just read it: 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. [0]

There's at least one implementation that I'm aware of in MoltenGL (https://moltengl.com/moltengl/), though that's only ES.
There is also MoltenVK https://github.com/KhronosGroup/MoltenVK for Vulkan on metal...
A reasonable alternative would be to implement OpenGL on top of Metal for compatibility but this is a lot of work.
