At the time of writing, Harbor is in the private preview stage. A Harbor page is available on Claris's website, which appears to state that it can “run open-weight models locally on Macs equipped with Apple silicon,” “be set up within minutes,” “connect multiple Macs using Thunderbolt 5 to share memory,” and “store data on the Mac without exposing it externally.”


Aaron Perris, who is well versed in Apple-related information, posted about Harbor's features on X. He also posted images that appear to have been obtained from the App Store.


Below is an image posted by Perris. It shows the MLX-compatible version of “gpt-oss-20b” being downloaded within the Harbor app.


The following screenshot shows “Llama 3.6-2-Instruct-4bit” running on a MacBook Pro equipped with an M5 chip.


There is also a management screen for handling three Macs connected via Thunderbolt 5 as a single cluster.


Harbor is at the private preview stage, and the timing of the official release is unknown.

In addition, Apple is also developing an application called “Minions” that connects multiple Macs to build a virtual GPU cloud.
