TL;DR: Apple's new M6 MacBook Pro starts at $1,999 in the US, while the M6 iMac starts at $1,499; both start with 16GB of unified memory and can reach 32GB only in specific configurations.<sup><a href="#source-1">[1]</a></sup><sup><a href="#source-2">[2]</a></sup><sup><a href="#source-3">[3]</a></sup><sup><a href="#source-4">[4]</a></sup> For local language models, choose the memory and software path first. Apple's reported AI speedups use different workloads and comparison machines, so they cannot rank these two Macs as local inference systems.

Apple announced the 14-inch MacBook Pro with M6 and the 24-inch iMac with M6 on October 27. US preorders opened October 28; delivery and store availability begin November 6. As of this October 30 analysis, buyers can configure a machine, but there is no retail M6 unit here to benchmark.<sup><a href="#source-1">[1]</a></sup><sup><a href="#source-2">[2]</a></sup>

The real story isn't that Apple put “AI” in two more product announcements. It is that buyers now have to decide which work must run on their own Mac, what model and context that work requires, and whether a fixed memory ceiling leaves room for the rest of their applications. A chip claim cannot answer those questions.

Both machines arrive with 16GB standard, while a 32GB iMac requires the 12-core CPU and 12-core GPU configuration; the 10-core iMac stops at 24GB. The MacBook Pro offers 16GB, 24GB, or 32GB. Those are purchase-time choices, because the technical specifications list memory as configurations rather than an upgrade path.<sup><a >[3]</a></sup><sup><a >[4]</a></sup>

The Buying Fork: Same Chip Name, Different Constraints

The M6 MacBook Pro is the portable option: 12 CPU cores, 12 GPU cores, a Dual 16-core Neural Engine, a 14.2-inch display, and Apple-rated battery life of up to 24 hours. The base US price is $1,999. Apple's specifications distinguish 153GB/s memory bandwidth for the 16GB model from 170GB/s for the 24GB and 32GB models. That distinction is easy to miss in a press release that summarizes bandwidth as “up to 170GB/s.”<sup><a href="#source-1">[1]</a></sup><sup><a href="#source-3">[3]</a></sup>

The iMac is a fixed desk with a 24-inch 4.5K display. Its $1,499 US entry configuration has a 10-core CPU and 10-core GPU; the 12-core/12-core model starts at $1,699. Both start with 16GB, but the former can be configured to 24GB and the latter to 24GB or 32GB. Apple lists up to 170GB/s bandwidth for the iMac, without a configuration-by-configuration breakdown on the spec page.<sup><a href="#source-2">[2]</a></sup><sup><a href="#source-4">[4]</a></sup>

Here's the genius of the iMac offer: its lower starting price buys a complete desk setup. The uncomfortable truth for a local-model buyer is that the cheapest iMac cannot be ordered with 32GB. Compare the configured checkout total, not just the two entry prices. Storage matters too: Apple lists 256GB standard on iMac and 1TB on the M6 MacBook Pro. A model library competes with ordinary files for that space.<sup><a href="#source-3">[3]</a></sup><sup><a href="#source-4">[4]</a></sup>

Memory Is the Limit: A Model Must Share the Machine

Apple silicon's unified memory is accessible to the CPU and GPU. MLX documents that the same arrays can be operated on by either without a copy between separate CPU and GPU pools.<sup><a href="#source-5">[5]</a></sup> That is useful for local inference, but “32GB unified” never means 32GB exclusively reserved for a model. macOS, the interface, browser tabs, model weights, and the growing attention cache all use memory. LM Studio's own getting-started guide says loading a model allocates memory for its weights and other parameters.<sup><a href="#source-7">[7]</a></sup>

Quantization can shrink model weights, but its exact memory and quality tradeoffs depend on the model and format. MLX-LM supports quantized...
