Apple has withdrawn its Harbor application from the App Store, removing a software tool designed to let users link multiple computers to run large artificial intelligence models without relying on the cloud. The application allowed the execution of open-weight models directly on Apple silicon, ensuring that processed data remained on the local hardware for privacy.
The app, which was in private preview under the Claris brand, utilized Thunderbolt 5 to automatically cluster two or more Macs and pool their unified memory. This setup enabled the local processing of AI models that exceeded the memory capacity of a single machine and supported higher concurrency, all while eliminating the need for manual command line configuration.
