What is the issue?
Issue Description
Describe the bug
When attempting to run a model (e.g., x/flux2-klein) on an Apple Silicon Mac (arm64), the model fails to load with an MLX initialization error. The error indicates that /Applications/Ollama.app/Contents/Resources/libmlxc.dylib is compiled for x86_64 and is missing the arm64 architecture slice.
While the main ollama CLI executable is correctly built as a Universal Binary (containing both x86_64 and arm64), the bundled libmlxc.dylib library inside the macOS app bundle appears to be Intel-only, causing dlopen to fail on Apple Silicon.
Steps to reproduce
- Install Ollama on an Apple Silicon (M-series) Mac.
- Run the command:
ollama run x/flux2-klein(or potentially any model utilizing the MLX runner). - Observe the crash/error.
Expected behavior
The model should load and run natively using the arm64 architecture and Apple's MLX framework without dynamic library architecture mismatches.
Actual behavior / Error logs
ollama run x/flux2-klein

TL;DR
The most likely fix is to recompile the libmlxc.dylib library to include the arm64 architecture slice, ensuring compatibility with Apple Silicon Macs.
Guidance
- Verify the architecture of the
libmlxc.dyliblibrary using thefilecommand orlipotool to confirm it only containsx86_64architecture. - Recompile the
libmlxc.dyliblibrary with support for bothx86_64andarm64architectures to create a Universal Binary. - Update the Ollama app bundle with the recompiled
libmlxc.dyliblibrary. - Test the Ollama app on an Apple Silicon Mac to ensure the model loads and runs without errors.
Example
No specific code snippet is provided as the solution involves recompiling a library, which is typically done using build tools like Xcode or command-line compilers.
Notes
This solution assumes that the libmlxc.dylib library can be recompiled with the necessary architecture support. If the library is third-party or proprietary, alternative solutions may be needed, such as contacting the library vendor for an updated version or exploring other workarounds.
Recommendation
Apply a workaround by recompiling the libmlxc.dylib library to include the arm64 architecture slice, as this is the most direct solution to resolve the compatibility issue with Apple Silicon Macs.
