Claris is testing Harbor, a Mac app designed to run openweight artificial intelligence models locally and link multiple Apple silicon computers into a shared system. The app is in private preview and is not publicly available, according to its described product materials and reporting about the test.

The description says Harbor can run models on one Mac, keeping data on the device rather than sending it to cloud services. For larger workloads, it can connect two or more Macs over Thunderbolt 5 and pool their unified memory.

Harbor is also described as managing model downloads and setup within the app. Its materials say it detects connected Macs automatically and does not require command-line use or manual configuration. Those capabilities have been presented as a way to simplify local AI computing, though the reported features are drawn largely from a leaked app description and have not been independently demonstrated in the supplied reporting.

Claris, an Apple subsidiary known for its FileMaker database software, is conducting the private preview. A Harbor...
