A Real macOS Desktop for a Linux Agent: Driving Tart VMs over SSH with Agent Skills

Last time we put a full IntelliJ IDEA inside a Docker container. But Docker only gives you Linux, and some GUIs are macOS — Aqua, Gatekeeper, TCC prompts and all. So we taught a Linux AI Agent to boot, see, and drive a real macOS desktop inside a Tart VM over SSH, and packaged the whole thing as reusable Agent Skills you can point at any Apple Silicon Mac.
