Hello,

Only Apple Silicon (M1/M2/M3) are supported locally on Mac.

Ok...

Imagine on Linux you support only M1 M2 M3......

On Linux it supports whatever NVIDIA/AMD support. On Mac it supports whatever Apple supports. And Apple has deliberately cut off NVIDIA cards and never implementedr AI/ML for them.

That being said, GT 750M doesn't work for this stuff on any OS, it's few generations too old.
