Thanks @cki, I have been following your discussion a bit with the hope we may reach the ability to keep OpenGL working on macOS despite the deprecation.
On my side I am mainly interested for now by software rendering with Mesa. I can get it working on Ubuntu and Linux but unfortunately not on macOS, see “Failing to load Mesa3D on macOS instead of macOS provided OpenGL library”. Would you tell me how you got Mesa working on macOS?
You can get MESA to work but it will use the system’s OpenGL.framework library.
How can you state this? Is there really no way to bypass the OS GL framework?
