Original GitHub issue: https://github.com/ollama/ollama/issues/14350

On every ollama list and ollama run llama3:latest command I get a warning:

2026/02/21 19:53:40 WARN MLX dynamic library not available error="failed to load MLX dynamic library (searched: [/opt/homebrew/Cellar/ollama/0.16.3/bin /Users/igorgurkovskiy/build/lib/ollama])"

Models run normally, but the warning appears every time.
Environment
	•	OS: macOS (Apple Silicon, M‑series)
	•	Install method: Homebrew
	•	Ollama version: 0.16.3 (from  brew reinstall ollama )
	•	MLX version: 0.30.5 (from  brew install mlx )
	•	Output of  brew --prefix :
	•	 brew --prefix ollama  →  /opt/homebrew/opt/ollama 
	•	 brew --prefix mlx  →  /opt/homebrew/opt/mlx 
What I expected to happen
Since  mlx  is installed via Homebrew and  libmlx.dylib  is present, I expected Ollama to detect and use the MLX backend without warnings.
What actually happens
Even after reinstalling Ollama and MLX, and after exporting:

export DYLD_LIBRARY_PATH=/opt/homebrew/opt/mlx/lib:$DYLD_LIBRARY_PATH

I still get:

WARN MLX dynamic library not available error="failed to load MLX dynamic library (searched: [/opt/homebrew/Cellar/ollama/0.16.3/bin /Users/igorgurkovskiy/build/lib/ollama])"

Ollama appears to search only in these two hardcoded paths and does not look into the standard Homebrew  mlx  prefix.
Additional details
	•	 libmlx.dylib  exists at  /opt/homebrew/opt/mlx/lib/libmlx.dylib .
	•	Ollama itself is installed in  /opt/homebrew/Cellar/ollama/0.16.3  and symlinked via  /opt/homebrew/opt/ollama .
	•	Models such as  llama3:latest  and  ministral-3:latest  run successfully; only the MLX warning is shown.
Questions
	•	Is there a recommended way to configure the MLX search path for the Homebrew install?
	•	Should Ollama automatically look for  libmlx.dylib  in  /opt/homebrew/opt/mlx/lib  on Apple Silicon?
	•	Is this expected behavior (just a harmless warning), or a misconfiguration/bug?

Thank you!
