How we got this verdict
64 - 5 = 59GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
Because MacBook Pro has enough unified memory to spare, 31B fits at SFP8 (8-bit)— a higher-precision quant than most setups get. You don't need the 4-bit QAT build here, though it's still a safe download if you want a smaller file for a second model running alongside it.
Going up to 128GB (128GB) doesn't change the top recommendation — 31B is still the best fit, just with more headroom.
Real-world notes for this configuration
64GB is a Max-chip-only configuration on the MacBook Pro — no base or Pro-chip model has offered this much memory. It's a genuinely high-end portable configuration, aimed at users who want workstation-class local AI capacity without giving up a laptop form factor.
- ⚠At this memory tier and chip class, sustained heavy inference draws enough power that battery runtime drops sharply — plan on staying plugged in for long sessions.

FAQ
Can a MacBook Pro (64GB) run the 31B flagship model?
Yes, comfortably — Gemma 4 31B fits at SFP8 (8-bit) (~30.4GB), using 59GB of usable memory on this configuration.
What's the best Gemma 4 model for a MacBook Pro (64GB)?
Gemma 4 31B at SFP8 (8-bit) (~30.4GB) is the best fit — it's the largest model that runs comfortably within the 59GB of usable memory here.
What if I have more or less memory than 64GB?
With more (e.g. 128GB), you can run larger models or the same model more comfortably — see the MacBook Pro page. With less (e.g. 48GB), the best-fitting model gets smaller or tighter — see the MacBook Pro page.
Is 64GB overkill for Gemma 4 on a MacBook Pro?
For the current five-model lineup, even the 31B flagship's full BF16 weights (58.3GB) technically fit within the usable memory at this tier — so 64GB covers the entire lineup at full precision, with headroom to spare for the Max chip's higher-bandwidth compute.
Does 64GB require the Max chip specifically on a MacBook Pro?
Yes — 64GB hasn't been offered on the base or Pro-chip MacBook Pro configurations; it's exclusively a Max-chip build-to-order option.
