Running MiniMax H3 Locally on Mac Fails: Incomplete MPS Operator Support
fsdl44441 · reddit · 2026-08-03
A user encountered technical obstacles while trying to run the MiniMax H3 video generation model locally on a Mac. Using the quantized model weights (minimaxh3fl2vaprunedint8convrot.safetensors), the system threw an error regarding incomplete MPS (Metal Performance Shaders) operator support.
The poster is seeking a fix and asking about the actual inference performance if successfully running on Mac.
