Harbor

Claris, a wholly owned Apple subsidiary, is testing Harbor, an app that turns Apple-silicon Macs into local AI inference servers and can link multiple Macs over Thunderbolt 5 to run larger models. The app emphasizes zero-configuration setup, auto-detecting Thunderbolt 5 devices and letting users browse and download open-weight models, backed by Thunderbolt 5 RDMA support shipped in macOS Tahoe 26.2. Harbor remains in early access and is not yet publicly available.

Leaker Aaron Perris has uncovered evidence of a new Apple Mac app called Harbor that turns one or more Macs into a private AI inference server for running local models. The app is currently in private preview under Apple's Claris brand and is expected to launch publicly in the coming weeks or months.
