# Can I Run Qwen3-Coder 30B on Mac Mini M4 Pro 48GB? Local Coding Sizing

> **Direct Compatibility Verdict**: Yes, Qwen3-Coder 30B-A3B runs flawlessly on the 48GB Mac Mini M4 Pro. At Q4_K_M (20.66 GB total), it fits well within macOS Metal's default 75% limit (36GB allocatable of 48GB) with +15.34 GB headroom. It generates code at ~42 tok/s silently and handles 32k repository contexts at ~25.16 GB without SSD swap or thermal throttling.

## Key Memory Physics
| Metric | Value |
|---|---|
| Target AI Model | Alibaba Qwen3-Coder 30B-A3B (MoE) |
| Target Hardware | Apple Mac Mini M4 Pro (48GB Unified Memory) |
| Q4_K_M VRAM Required | 20.66 GB |
| Available Headroom | +15.34 GB |
| Estimated Generation Speed | ~42 tok/s |

## Hardware Physics & Bottleneck Analysis
Qwen3-Coder 30B-A3B activates only 3.3B parameters per token from its 30.5B MoE architecture across 48 layers. Apple's M4 Pro delivers 273 GB/s unified memory bandwidth. Because the GPU and CPU share the same physical DRAM pool, agentic coding tools like Claude Code, Cursor, or Aider ingest multi-file repository contexts without PCIe transfer lag.

## Tier 1 Free Software Optimization ($0)
Increase the macOS Metal allocation limit by running `sudo sysctl iogpu.wired_limit_mb=40960` in Terminal. This expands allocatable unified memory from 36GB to 40GB, allowing 64k repository context windows with zero swap.
