Apple's Claris Previews Harbor: A Private AI Inference Server for Apple Silicon Macs That Runs Open-Weight Models Locally and Pools Unified Memory Across Thunderbolt 5 Clusters, Early-Access Sign-Up Only
Apple subsidiary Claris, the maker of FileMaker, has put up an official early-access page for Claris Harbor, labeled "Private Preview". According to Claris, Harbor turns the Apple silicon Macs you own into a private AI server that runs open-weight models with zero cloud fees, no per-token billing, and prompts and data that never leave your hardware. A single Mac can host an endpoint in minutes, and for larger models several Macs can be connected over Thunderbolt 5 to pool unified memory. The product surfaced when MacRumors analyst Aaron Perris posted a briefly live App Store listing on X (about 500K views); the listing was then pulled. Claris has given no release date, price or list of supported Macs, and the page only offers a sign-up form.
