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.

Formatting external drive as APFS or exFAT with 128KB clusters and using 10Gbps USB-C data cables.

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

1. Format the external SSD on a Mac as APFS for optimal sequential write consistency.
2. Ensure cable is rated for 10Gbps or 20Gbps (USB 3.2 Gen 2×2); in-box white charging cables are USB 2.0 (40MB/s).
3. Use drives with sustained non-SLC cache write capabilities (e.g. SanDisk Extreme Pro v2 or Crucial T700 enclosures).

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