@ce72be9b Apple was still selling Macs with NVIDEA GPUs in 2015, and NVIDEA was still providing driver updates after that time, until Apple apparently decided to stop letting them do so. Apple wasn’t “stuck” with AMD. It seems like there was some kind of dispute involving CUDA after Metal debuted on the Mac in El Capitan. https://blog.greggant.com/posts/2021/10/13/apple-vs-nvidia-what-happened.html 

 @538a1fbd The two companies do not like each other, it's that simple.
