Original GitHub issue: https://github.com/ollama/ollama/issues/15480

What is the issue?

Installed Ollama using Homebrew: brew install ollama.

Ollama works fine with models that do not require MLX support? However, ollama run qwen3.5:35b-a3b-coding-nvfp4 returns the following error.

Error: 500 Internal Server Error: mlx runner failed: Error: MLX not available: failed to load MLX dynamic library (searched: [/opt/homebrew/Cellar/ollama/0.20.5/bin/lib/ollama /opt/homebrew/Cellar/ollama/0.20.5/bin]) (exit: exit status 1)

Note that the solution noted in https://github.com/ollama/ollama/issues/15433#issuecomment-4211344690 does not work either.

ln -s "$(brew --prefix mlx-c)/lib/libmlxc.dylib" "$(brew --prefix ollama)/bin" works, as mentioned in https://github.com/ollama/ollama/issues/15433#issuecomment-4226686209, closing the issue.
