OpenAI Orchard: Orchestrating Tart VMs on Apple Silicon Clusters

Repositoryopenai/orchardTool

Orchard is an orchestration system developed by OpenAI, written in Go, designed to run and manage Tart virtual machines across clusters of bare-metal Apple Silicon hardware via CLI and REST API.

Key points

  1. Orchestrates Tart VMs across bare-metal clusters of Apple Silicon devices.
  2. Offers an `orchard` CLI and a built-in REST API server for programmatic VM management.
  3. Includes a local development mode (`orchard dev`) running both the controller and a worker locally.
  4. Provides workarounds for macOS 15 Sequoia 'Local Network' privacy prompts via a dedicated helper process (`orchard localnetworkhelper`) or system defaults.

Why it matters

Scaling virtualization workflows on Apple Silicon has traditionally been challenging. Orchard enables teams to manage multi-node Mac clusters for automated CI/CD or testing environments using an orchestration layer tailored to Tart.

Analysis

Built upon Tart, Orchard addresses the challenge of managing virtual machines across a fleet of Apple Silicon devices. It provides a controller-worker architecture suitable for infrastructure engineers needing automated macOS virtualization. The project includes explicit mitigation for macOS Sequoia's local network privacy prompts, either via a root-initiated helper dropping privileges or global network preferences. With around 570 stars, it represents a focused, functional tool for bare-metal Mac automation.
