Apple's Claris Tests Harbor, a Local AI App for Macs
Apple subsidiary Claris is testing an app called Harbor that runs AI models on Mac computers.
The app is designed to run open-weight models locally on Apple silicon, so data stays on the user's hardware instead of going to the cloud.
Harbor can connect multiple Macs over Thunderbolt 5 and pool their memory to run larger models or handle more requests.
Apple's macOS Tahoe 26.2 added a technology that makes these Mac clusters faster.
Harbor is in early access and is not publicly available; its App Store listing has been removed.
Claris's sign-up page asks for a company name, but Apple has not said how it will market Harbor or whether it will be free.

Harbor automatically detects connected Macs and manages model downloads, aiming to avoid manual configuration and command-line use.
The app is in a private or early-access preview and is not publicly available.
