What is the issue?

Description

When attempting to run the x/flux2-klein model, Ollama fails with an MLX initialization error stating that libmlxc.dylib cannot be found.

Error Message

Error: 500 Internal Server Error: mlx runner failed: Error: failed to initialize MLX: libmlxc.dylib not found (exit: exit status 1)

Steps to Reproduce

  1. Run the command: ollama run x/flux2-klein "A cat holding sign say Hello World"
  2. Error occurs immediately during model initialization

Expected Behavior

The model should either:

  • Initialize successfully if MLX dependencies are properly bundled/installed
  • Provide a clear error message with instructions on how to install MLX dependencies
  • Fall back to a non-MLX backend if available

Actual Behavior

The model fails to run with a 500 Internal Server Error, and the MLX library cannot be found.

Originally created by @milindmore22 on GitHub (Apr 10, 2026). Original GitHub issue: https://github.com/ollama/ollama/issues/15471 ### What is the issue? ## Description When attempting to run the `x/flux2-klein` model, Ollama fails with an MLX initialization error stating that `libmlxc.dylib` cannot be found. ## Error Message ``` Error: 500 Internal Server Error: mlx runner failed: Error: failed to initialize MLX: libmlxc.dylib not found (exit: exit status 1) ``` ## Steps to Reproduce 1. Run the command: `ollama run x/flux2-klein "A cat holding sign say Hello World"` 2. Error occurs immediately during model initialization ## Expected Behavior The model should either: - Initialize successfully if MLX dependencies are properly bundled/installed - Provide a clear error message with instructions on how to install MLX dependencies - Fall back to a non-MLX backend if available ## Actual Behavior The model fails to run with a 500 Internal Server Error, and the MLX library cannot be found. ### Relevant log output ```shell time=2026-04-10T13:19:17.037+05:30 level=INFO source=routes.go:1752 msg="server config" env="map[HTTPS_PROXY: HTTP_PROXY: NO_PROXY: OLLAMA_CONTEXT_LENGTH:0 OLLAMA_DEBUG:INFO OLLAMA_DEBUG_LOG_REQUESTS:false OLLAMA_EDITOR: OLLAMA_FLASH_ATTENTION:false OLLAMA_GPU_OVERHEAD:0 OLLAMA_HOST:http://127.0.0.1:11434 OLLAMA_KEEP_ALIVE:5m0s OLLAMA_KV_CACHE_TYPE: OLLAMA_LLM_LIBRARY: OLLAMA_LOAD_TIMEOUT:5m0s OLLAMA_MAX_LOADED_MODELS:0 OLLAMA_MAX_QUEUE:512 OLLAMA_MODELS:/Users/milind/.ollama/models OLLAMA_MULTIUSER_CACHE:false OLLAMA_NEW_ENGINE:false OLLAMA_NOHISTORY:false OLLAMA_NOPRUNE:false OLLAMA_NO_CLOUD:false OLLAMA_NUM_PARALLEL:1 OLLAMA_ORIGINS:[http://localhost https://localhost http://localhost:* https://localhost:* http://127.0.0.1 https://127.0.0.1 http://127.0.0.1:* https://127.0.0.1:* http://0.0.0.0 https://0.0.0.0 http://0.0.0.0:* https://0.0.0.0:* app://* file://* tauri://* vscode-webview://* vscode-file://*] OLLAMA_REMOTES:[ollama.com] OLLAMA_SCHED_SPREAD:false http_proxy: https_proxy: no_proxy:]" time=2026-04-10T13:19:17.038+05:30 level=INFO source=routes.go:1754 msg="Ollama cloud disabled: false" time=2026-04-10T13:19:17.072+05:30 level=INFO source=images.go:499 msg="total blobs: 1553" time=2026-04-10T13:19:17.075+05:30 level=INFO source=images.go:506 msg="total unused blobs removed: 0" time=2026-04-10T13:19:17.076+05:30 level=INFO source=routes.go:1810 msg="Listening on 127.0.0.1:11434 (version 0.20.5)" time=2026-04-10T13:19:17.076+05:30 level=INFO source=runner.go:67 msg="discovering available GPUs..." time=2026-04-10T13:19:17.078+05:30 level=INFO source=server.go:444 msg="starting runner" cmd="/Applications/Ollama.app/Contents/Resources/ollama runner --ollama-engine --port 52713" time=2026-04-10T13:19:17.231+05:30 level=INFO source=types.go:42 msg="inference compute" id=0 filter_id=0 library=Metal compute=0.0 name=Metal description="Apple M3" libdirs="" driver=0.0 pci_id="" type=discrete total="11.8 GiB" available="11.8 GiB" time=2026-04-10T13:19:17.231+05:30 level=INFO source=routes.go:1860 msg="vram-based default context" total_vram="11.8 GiB" default_num_ctx=4096 [GIN] 2026/04/10 -
