Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 25.1 GB, but this setup only exposes 13.0 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, Granite 4.1 30B requires more memory than MacBook Pro M3 Pro 18GB provides.
Granite 4.1 30B (30B parameters) requires approximately 25.1 GB of memory with Q4_K_M quantization.
The recommended quantization for Granite 4.1 30B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 Pro 18GB, Granite 4.1 30B achieves approximately 2.9 tokens per second decode speed with a time-to-first-token of 66884ms using Q4_K_M quantization.
For coding workloads, Granite 4.1 30B on MacBook Pro M3 Pro 18GB receives a F grade with 2.9 tok/s and 4K context.
On MacBook Pro M3 Pro 18GB, Granite 4.1 30B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. MacBook Pro M3 Pro 18GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
