There are many GUIS for OpenGL, but OpenGL is no longer
supported on Macs AFAIK.
Indeed: openGL on all Apple platforms was finally deprecated on
2018 after Apple introduced its own proprietary Metal API.
I suggest using Skia instead:
I been reading about it:
Skia developed by google for C++ using openGL
- most similar in purpose to Cairo or PathFinder (meaning that it
focuses on drawing) rather than to other more elaborate
infrastructures like QT that provide their own widgets [skia @
wikipedia.org](https://en.wikipedia.org/wiki/Skia_Graphics_Engine)
- used by google Chrome, Chrome OS, Chromium OS, Mozilla FireFox
∧ ThunderBird, Android, FireFox OS, LibreOffice, etc
- supports several platform-dependent back-ends; including:
- CPU-based software rasterization
- GPU-accelerated openGL, openGL ES, Vulkan, and Metal
- PDF output
- SVG output ... partially implemented
