01

Sizing Memory: 36GB vs 64GB vs 128GB

Llama 3.3 70B in Q4_K_M quantization requires approximately 42GB of resident memory, making 64GB and 128GB M-Max machines ideal for local enterprise reasoning.

02

Raising macOS GPU Wired Memory Thresholds

Override default 75% macOS VRAM allocation caps via sysctl iogpu.wired_mem_limit to unlock up to 95% system RAM allocation for Metal compute.

03

Native Metal Compilation and Execution

Compile llama.cpp natively with GGML_METAL acceleration flags for sustained 25+ tokens/second throughput.
