Ollama, the popular open-source platform for running local AI models, has released a critical update to its MLX backend. The patch promises improved performance and stability on Macs with Apple chips, addressing long-standing compatibility issues. The update has already been merged into the main branch and is available for developers and enthusiasts.

Ollama, the go-to tool for running large language models like Llama and Mistral locally, just took a major step forward for Apple Silicon users. On August 19, 2026, the development team merged pull request #17850 into the main repository, updating the MLX backend—Apple's machine learning framework optimized for M1, M2, M3, and newer chips.

What is MLX and why does this update matter?

MLX is a framework created by Apple to accelerate AI model execution on its hardware. By integrating this update, Ollama aims to boost inference speed and stability on Macs. The most significant change is the temporary inclusion of a patch from the ml-explore/mlx-c project (issue #127), which fixes a compatibility issue found in recent versions.

According to the commit 00b18be, the modification touches 8 files with 108 additions and 4 deletions. Lead developer Daniel Hiltgen (known as dhiltgen) explained this is a temporary measure: “Temporarily carry ml-explore/mlx-c#127”.

Technical details and review process

The pull request was reviewed and approved by Jesse Gross (jessegross), another core contributor. After the merge, 17 continuous integration checks all passed. Additionally, the development branch mlx_bump was deleted, and a follow-up PR #17874 was opened to “plumb the temporary patch into the Docker stages,” ensuring the fix also reaches containerized environments.

“This update is a step forward in consolidating Ollama as the preferred choice on Apple hardware,” commented a community member in the GitHub thread.

For end users, the improvement will be especially noticeable when loading large models and during real-time interactions with local assistants.
