Apple M2 Max 64GB unified (MacBook Pro / Mac Studio) for Local LLMs: VRAM and Model Fit
64 GB unified memory is unified memory, not discrete VRAM added to RAM: 68,719,476,736 bytes (64.00 GiB). The default system reserve is 10,737,418,240 bytes (10.00 GiB), and the net is 57,982,058,496 bytes (54.00 GiB).
Apple M2 Max 64GB unified (MacBook Pro / Mac Studio): 64.00 GiB gross, default reserve 10.00 GiB, net calculator budget 54.00 GiB. Advertised 64 GB unified memory is treated as 64 GiB (2^30 bytes). Unified memory is a shared CPU/GPU pool; ~10 GiB default reserve covers macOS and other processes on a 64GB machine.

The reserve is a configurable calculator assumption, not a measured desktop tax. Headless systems can lower it after measuring baseline board usage.
Catalog fit at 8,192 tokens
Each row is the same automatic pick as the calculator at 8,192 tokens: the highest precision at or above 3 bits per weight that fits. A file under that floor stays available for a manual choice and is not the automatic row. Concurrent sequences = 1, FP16 KV. Fit and software support are separate. Format compatibility is not a verified run.
