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 Command R+ 104B with a B grade (Tight fit). Expected decode speed: 10.3 tok/s.
Command R+ 104B (104B parameters) requires approximately 81.6 GB of memory with Q4_K_M quantization.
The recommended quantization for Command R+ 104B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 128GB, Command R+ 104B achieves approximately 10.3 tokens per second decode speed with a time-to-first-token of 18805ms using Q4_K_M quantization.
For coding workloads, Command R+ 104B on MacBook Pro M4 Max 128GB receives a B grade with 10.3 tok/s and 66K context.
On MacBook Pro M4 Max 128GB, Command R+ 104B can safely use up to 66K 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.
