GitHub Actions: macOS 15 and Windows 2025 images are now generally available

macOS 15 and Windows 2025 images are now generally available for all GitHub-hosted runners. You can use these images in your workflows on GitHub-hosted standard or larger runners.

Get started today

To use macOS 15 directly, update runs-on: in your workflow file to macos-15, macos-15-xlarge, or macos-15-large.

jobs:
  build:
    runs-on: macos-15
    steps:
      - uses: actions/checkout@v4
      - name: Build
        run: swift build
      - name: Run tests
        run: swift test

To use Windows 2025, you can target the image directly on standard runners using runs-on: windows-2025. For larger runners, create a runner and select Windows Server 2025 in the Images UI console.

The latest tag will migrate to these images later in the year.
