Overview
- Screenshots and an App Store preview obtained Tuesday by leaker Aaron Perris show Claris is testing an app called Harbor that aims to make a Mac act as a private AI inference server.
- Harbor’s interface is reported to let users browse, download, and load open-weight models inside the app while handling model management so no command-line setup is needed.
- The app is described as detecting Thunderbolt 5-connected Macs and pooling their unified memory for larger models or higher concurrency, using RDMA support added in macOS Tahoe 26.2 to speed clustering.
- Harbor is currently in a private early preview and not publicly available, and a sign-up form that requests a company name suggests Apple is positioning it toward business or enterprise users.
- The feature set emphasizes on-device privacy and ease of use but faces existing free alternatives like Exo for clustering and LM Studio for single-Mac use, and its real impact will depend on availability, pricing, and how it compares to those tools.
