According to ChainCatcher citing Gelonghui, Apple is developing Harbor, a Mac app that turns Apple silicon computers into private AI inference servers. The app lets users download, manage, and run open-weight models locally without uploading data to the cloud.

Harbor can also connect two or more compatible Macs over Thunderbolt 5, automatically creating a cluster and pooling unified memory to run models that exceed a single computer’s capacity or handle more concurrent requests. It requires no manual configuration or command-line use. Apple software subsidiary Claris is currently conducting a private preview, and no public release date has been announced.
