Original GitHub issue: https://github.com/ollama/ollama/issues/14663

What is the issue?

Environment

Hardware: Apple M4 Mac

OS: macOS

Ollama version: v0.17.7

Install method: curl https://ollama.com/install.sh | sh

Binary: /usr/local/bin/ollama

No Homebrew version install

Desktop app removed (/Applications/Ollama.app)

Issue

Running any CLI command (e.g. ollama --version) emits:

Mar 6 2026 02:05:57 - ERROR - generated.c:2302 - CHECK failed: mlx_array_item_float16_
ERROR Failed to load MLX dynamic library symbols path=/Applications/Ollama.app/Contents/Resources/libmlxc.dylib
WARN MLX dynamic library not available error="failed to load MLX dynamic library (searched: [/Applications/Ollama.app/Contents/Resources /build/lib/ollama])"

Key points

Occurs during CLI initialization, before server start or model loading.

Ollama attempts to load libmlxc.dylib and fails due to missing symbol mlx_array_item_float16_.

Issue persists after removing ~/.ollama, ~/Library/Application Support/Ollama, and reinstalling.

Expected behavior

ollama --version should return the version without attempting MLX runtime initialization or producing symbol-load errors.

Suspected cause

Binary/runtime mismatch between Ollama and the MLX C library (libmlxc.dylib), resulting in a missing exported symbol (mlx_array_item_float16_).

Relevant log output

OS

macOS

GPU

Apple

CPU

Apple

Ollama version

0.17.7

I got the same error on my Intel Macbook Pro (running MacOS 15.7.3) using the .dmg installer downloaded from the Ollama website. However, after uninstalling Ollama completely, I was able to install it via homebrew just fine
