A Claris page lists setup in minutes, memory sharing across multiple Macs connected by Thunderbolt 5, and data stored on the Mac rather than exposed externally. Harbor is in private preview, and the release timing is unknown. Apple is also developing Minions, which links Macs into a virtual GPU cloud.","whyItMatters":"Harbor and Minions both treat a pile of Macs as shared compute, which puts Apple's local AI pitch on hardware people already own rather than on cloud capacity.","webCardHtml":"\u003cp\u003eScreenshots posted by Aaron Perris show the app downloading an MLX-compatible build of gpt-oss-20b, running Llama 3.6-2-Instruct-4bit on a MacBook Pro with an M5 chip, and managing three Macs joined over Thunderbolt 5 as one cluster. Claris lists the app as private preview, with no release date given.\u003c/p\u003e\u003cp\u003eThe memory sharing is the part worth watching. A single Mac\u0026#39;s unified memory caps the model size it can hold, and pooling several machines over a cable raises that ceiling without a datacenter. Harbor is not the only project on that idea: Apple is also developing Minions, which gathers unused Macs into a virtual GPU cloud.\u003c/p\u003e","blueskyPost":"Claris lists Harbor as private preview with no release date, and Apple is separately building Minions for a virtual GPU cloud.
