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 M4 Max 128GB can run Qwen 2.5 72B with a A grade (Runs well). Expected decode speed: 14.9 tok/s.
Qwen 2.5 72B (72B parameters) requires approximately 63.5 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 2.5 72B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 128GB, Qwen 2.5 72B achieves approximately 14.9 tokens per second decode speed with a time-to-first-token of 13019ms using Q4_K_M quantization.
For coding workloads, Qwen 2.5 72B on MacBook Pro M4 Max 128GB receives a A grade with 14.9 tok/s and 110K context.
On MacBook Pro M4 Max 128GB, Qwen 2.5 72B can safely use up to 110K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Max 128GB 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.
