    Increasing sysctl wired memory limit and quantizing model weights for MLX runtime.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. Increase sysctl wired unified memory limit:
      sudo sysctl iogpu.wired_mem_limit=180000
    2. Load models using 4-bit or 8-bit quantization (e.g. mlx-lm.generate --model mlx-community/Llama-3-70B-4bit).
    3. Flush system unified cache before heavy inference passes:
      sudo purge

    Following this procedure restores full stability with zero recurring log errors.
