Leaker Aaron Perris has uncovered evidence of a new Mac app in the works at Apple called Harbor, which makes it easy to run local AI models on one or more Macs. New ‘Harbor’ app revealed at Apple: ‘turn your Mac into a private AI inference server’ The Mac has become much more popular this year, both for its budget options like the MacBook Neo but also as a tool for running AI models locally on Mac Studio, Mac mini, and more. It seems that Apple plans to lean more towards the latter use case, as leaker Aaron Perris discovered a new Mac app called Harbor that has been designed to turn your Mac into a private AI inference server. Here’s Perris’ post on X with the details: Apple is working on a new app called HarborHarbor that turns your Mac into a private AI inference server.

Run open models locally on Apple Silicon – your data never leaves your hardware and nothing ever reaches the cloud. Connect multiple Mac computers via Thunderbolt 5 to pool unified memory, enabling large models and greater concurrency than a single computer can handle on its own. And here are the standout features: Setup in minutes, not hours: “Harbor automatically detects your devices via Thunderbolt 5 to form a cluster. Plug it in, boot up, and you’re up and running—no manual configuration, no command line, no infrastructure experience required.” Download and run models directly: “Browse, download, and load open weight models from the app. Harbor handles model management so you can focus on work, not configuration.” Cluster to scale: “Connect two or more Thunderbolt 5-capable Mac computers and Harbor pools their unified memory into a single inference resource. Run models that exceed the capacity of any one computer or serve more concurrent requests across your entire cluster.” Harbor is currently in private preview under Apple’s Claris brand, but it seems likely we’ll see it launch to the public in the coming weeks and months.
