self-hosted-macos-runner

GitHub-hosted macOS minutes are the most expensive Actions SKU, and an iOS repo with a UI-test or screenshot matrix burns them on every push. A Mac you already own can run the same jobs as a self-hosted runner: no hosted minutes, Xcode and simulator runtimes already installed, and the same Mac doubles as a remote Xcode build box.

Pricing moves: check GitHub's current Actions billing docs before quoting a saving. As of late 2026 self-hosted minutes carried no per-minute charge; a small per-minute platform fee for self-hosted runners was announced for 2026 and then postponed, not cancelled.
