Agents or code create a sandbox (a macOS 27 user account on a Mac Studio M5 Max) via API/SDK, run commands, read/write files, take screenshots or run screen-agent goals, then kill it. Tasks offer fire-and-forget CI that clones a repo, runs a command and keeps artifacts. GitHub Actions jobs run by setting runs-on: offstage-macos. Gives agents and CI a real Mac for Xcode, Swift and iOS Simulator work without 24-hour minimum Mac rentals or expensive per-minute runners. Built for: Developers using AI coding agents (Claude Code, Codex, Cursor) and teams needing macOS CI for Xcode/Swift builds. Main features: Sandbox API with headless or gui sessions; Xcode 27.2, Swift, iOS 27.2 simulator preinstalled; GitHub Actions runner via runs-on: offstage-macos / offstage-macos-gui; Tasks: clone, run command, collect artifacts; runAgent: Claude carries out a goal on the Mac desktop; Screenshots and recorded replays for 7 days.
