Can I run Granite 4.1 30B on Apple M5 Max (128GB)?
Yes. Granite 4.1 30B runs on Apple M5 Max (128GB) at Q4_K_M (~19.1 GB of ~96 GB usable).
Runs at Q4_K_M using ~19.1 GB of ~96 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. Apple M5 Max (128GB) leaves ~76.9 GB of headroom, room to step up to FP16 for higher quality.

How much memory does Granite 4.1 30B need?
Apple M5 Max (128GB) has room to spare. At Q4_K_M the weights are ~17 GB; with KV cache and runtime overhead, budget ~19.1 GB at a 4k context.
What is the best tool to run Granite 4.1 30B on macOS?

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
