Marked-up Mac minis flood eBay amid shortages driven by AI

Apple’s base M4 Mac mini is sold out across configurations, with higher-storage models facing delays.

Buyers are turning to eBay, where new, used, and refurbished units are listed well above retail.

The surge appears linked to local AI workloads, as users want compact, quiet Macs for running models on-device.

Broader memory supply pressure is also contributing to Apple’s inventory squeeze and secondary-market markups.
