Original GitHub issue: https://github.com/ollama/ollama/issues/15459

What is the issue?

I’m on an Apple Silicon Mac and ollama run x/z-image-turbo fails immediately.

This worked for me on February 26, 2026. Just in case it would help, I reinstalled Ollama, but the issue is still happening.

What I see:

  • uname -m -> arm64
  • file /Applications/Ollama.app/Contents/Resources/libmlxc.dylib -> Mach-O 64-bit dynamically linked shared library x86_64
  • file /Applications/Ollama.app/Contents/MacOS/Ollama -> universal binary with x86_64 and arm64

Server log shows Ollama starting an MLX image runner for x/z-image-turbo, then failing to initialize MLX because libmlxc.dylib is the wrong architecture.

Please let me know if there are any other details that I can provide that would help isolate the issue.

OS

macOS 26.4

CPU

M4 Pro

Ollama version

0.20.4

@rick-github Will this roll into a release? It says 0.20.4 but as of 0.20.6 still not fixed.

The stale library issue should have been resolved with 0.20.5. Is your error still about libmlx.dylib? There are other Mac specific issues that should be resolved in 0.20.7.

@rick-github The error message re: MLX was the same. Happy to try it out. But it wasn't fixed and in the duplicate ticket that you referenced others are commenting the same.
