Setup tutorial: Qwen 2.5 Coder 7B on M3 Max
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen 2.5 Coder 7B on an Apple M3 Max with Q8_0 quantization for Grade S performance at ~281 tok/sec.
Prerequisites
Before starting, ensure you have at least 15GB of free disk space, macOS 12.3 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install`.
Expected performance
With the Q8_0 quantization, you can expect ~281 tok/sec performance, utilizing 8.0GB of VRAM. Given the 128GB total VRAM, you will have approximately 120.0GB of headroom for context, allowing for a practical context window of up to 32768 tokens.
1. Install runtimeOllama (preferred on Apple Silicon)
brew install ollama

Download the Qwen 2.5 Coder 7B Q8_0 quantized model (7.5GB file) from Hugging Face.
ollama pull Qwen/Qwen2.5-Coder-7B-Instruct-GGUF:qwen2.5-coder-7b-instruct-q8_0.gguf3. Run it
ollama run Qwen/Qwen2.5-Coder-7B-Instruct-GGUF:qwen2.5-coder-7b-instruct-q8_0.gguf
ollama chat4. Optimize for M3 Max
To optimize performance on the Apple M3 Max, ensure you are using the Metal/MLX backend. The unified memory architecture allows efficient use of the 128GB VRAM, which is crucial for handling large context windows and maintaining high token throughput. Use the `--metal` flag with Ollama to leverage the Metal Performance Shaders (MPS) layers for accelerated inference.
Troubleshooting
Inference is slow or unresponsive
Ensure the Metal/MLX backend is enabled with `ollama config set backend metal`. Restart the Ollama service with `ollama restart`.
Out of memory errors during inference
Reduce the context length to a lower value, such as 16384, to fit within the available VRAM. Use `ollama config set context_length 16384`.
Model not found after pulling
Verify the model path and ensure it matches the downloaded file. Use `ollama list` to check the available models and their paths.
Alternative runtimes
While Ollama is the preferred runtime for Apple Silicon, you can also use LM Studio, llama.cpp, or MLX for different use cases. LM Studio provides a graphical interface and is useful for quick prototyping. llama.cpp offers more fine-grained control over quantization and performance tuning. MLX is another option for leveraging Metal Performance Shaders, but it may require additional setup steps.
