How we got this verdict
36 - 5 = 31GB usable (macOS and background processes reserve roughly 5 GB of unified memory).
31B lands on Q4_0 here, so grab the official QAT (quantization-aware training) checkpoint instead of a generic Q4_0 quant. Google shipped a full-quality QAT build for 31B at essentially the same ~19GB download size, with noticeably better output quality than a naive 4-bit quant. See the QAT guide for exact file names.
Going up to 48GB (48GB) doesn't change the top recommendation — 31B is still the best fit, just with more headroom. One tier down, at 24GB, the best fit drops to 12B (comfortable) instead.
Real-world notes for this configuration
36GB has been the Max chip's standard entry configuration across recent MacBook Pro generations (M3 Max and M4 Max), and it also doubled as the top build-to-order option for the M3 Pro chip. Either way, 36GB reliably signals you're at or near the top of what the MacBook Pro line offers below the true Max-chip tier — Apple's highest MacBook Pro memory-bandwidth chip short of the Mac Studio's Ultra option.
- ⚠Max-chip MacBook Pros are meaningfully heavier and drain battery faster under sustained load than the base/Pro-chip models — factor that into a portable local-AI setup, not just the memory number.

FAQ
Can a MacBook Pro (36GB) run the 31B flagship model?
Yes, comfortably — Gemma 4 31B fits at Q4_0 (4-bit) (~17.4GB), using 31GB of usable memory on this configuration.
What's the best Gemma 4 model for a MacBook Pro (36GB)?
Gemma 4 31B at Q4_0 (4-bit) (~17.4GB) is the best fit — it's the largest model that runs comfortably within the 31GB of usable memory here.
What if I have more or less memory than 36GB?
With more (e.g. 48GB), you can run larger models or the same model more comfortably — see the MacBook Pro page. With less (e.g. 24GB), the best-fitting model gets smaller or tighter — see the MacBook Pro page.
Does 36GB mean I have the Max chip MacBook Pro?
Usually, though not always — 36GB is the Max chip's standard configuration in recent generations, but it has also been sold as the top build-to-order option on the M3 Pro chip. Check the core count in the full spec sheet to be certain which one you have.
Is the Max chip's extra memory bandwidth worth it over a Pro-chip Mac at similar memory?
For sheer capacity the two can land close together, but Apple's published specs put the Max chip's memory bandwidth meaningfully above the Pro chip's — that tends to matter more for inference speed than for what fits, worth weighing based on whether speed or budget matters more to you.
