Overpriced Mac minis are flooding eBay amid shortages of the sold-out machines, which have become a favored tool for running on-device AI models like OpenClaw. This week, reports indicated that the $599 M4 Mac mini base model with 16GB RAM and 256GB of storage is sold out on Apple’s retail website, with no options for delivery or in-store pickup. The shortages have since extended to other configurations of the base model, regardless of the amount of memory selected.

As a result, eBay has become a secondary market for these in-demand computers. On the site, various configurations of the M4 Mac mini are available for sale at higher prices than if buying direct from Apple, which is no longer an option. Apple’s power-efficient Mac minis have become popular devices for testing and running at-home, on-device AI models, beginning with the OpenClaw craze but now extending to OpenClaw alternatives like ZeroClaw, other AI tools from Anthropic and OpenAI, Perplexity Computer, or other specialized local models. Unlike some PCs, Mac minis also run quietly and tend to be more reliable for 24/7 use, compared with laptop computers.

The shortage of the devices also comes alongside an industry-wide memory crunch and plans for a Mac mini refresh, according to Bloomberg. However, refreshes of product lines haven’t led to shortages before. Apple did not immediately respond to a request for comment. This perfect storm of supply chain stress and increased demand for AI-friendly machines has inflated the prices of used consumer electronics.

As of Friday morning, M4 base models with the 16GB RAM/256GB SSD configuration were selling at markups like $715-$795 for a new, “open box” model, and as high as $979 for an “excellent” refurbished version. Some “lightly used, pre-owned” Mac minis with this configuration were selling for around $700 — more than $100 more than the price of a new base model.

There was also a single listing for a $925 brand-new M4 Mac mini with the same 16GB RAM and 256GB storage; the listing warned in bright red text: “Last one.” While you still may be able to score a reasonably priced refurb if you keep a close eye out (or if you win an eBay auction where the bid has started at a lower price point), it seems that the demand for the device is going to keep prices up until Apple’s supply chain refreshes. And now that the Mac mini is unavailable, Apple has begun to see increased demand for the Mac Studio, too. That computer is also now sold out across several configurations.
