## In short

Claris Harbor, from Apple's Claris unit, turns Apple silicon Macs into a private AI server for open-weight models. Several Macs can be linked over Thunderbolt 5 to pool memory. It is in private preview.

## What it is

Claris Harbor is a new app from Claris, an Apple company, that turns Apple silicon Macs you own into a private AI inference server for open-weight models. Claris lists it as a private preview with an early-access sign-up; MacRumors and 9to5Mac reported it on 10 November after its App Store listing appeared and was then removed.

## How it works

A single Mac can serve as an endpoint, and Harbor can detect other Thunderbolt 5 Macs automatically and form a cluster that pools their unified memory for bigger models or more requests. MacRumors notes the clustering relies on RDMA over Thunderbolt 5, which Apple added in macOS Tahoe 26.2. Models are browsed, downloaded and loaded inside the app, with no command line.

## Why it matters

Running open models across several Macs today means tools like Exo plus manual setup. An Apple-made app that does it with no per-token billing and keeps prompts on company hardware could make local inference a normal option for small businesses. Claris has not given a price or launch date.

## Who it's for

Mac-based teams that want to run open-weight models on their own hardware
