This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Yes, MacBook Pro M3 Pro 36GB can run Gemma 2 9B with a B grade (Runs well). Expected decode speed: 20.9 tok/s.
Gemma 2 9B (9B parameters) requires approximately 15.7 GB of memory with Q4_K_M quantization.
The recommended quantization for Gemma 2 9B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 Pro 36GB, Gemma 2 9B achieves approximately 20.9 tokens per second decode speed with a time-to-first-token of 9244ms using Q4_K_M quantization.
For coding workloads, Gemma 2 9B on MacBook Pro M3 Pro 36GB receives a B grade with 20.9 tok/s and 8K context.
On MacBook Pro M3 Pro 36GB, Gemma 2 9B can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 Pro 36GB 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.
