GitHub Actions: macOS 14 (Sonoma) is now available

The macOS 14 runner image is now available for GitHub hosted runners. Workflows executed on this image will run exclusively on the 3 vCPU M1 runner announced earlier today. To use the runner, simply update the runs-on: key in your YAML workflow file to macos-14, macos-14-xlarge, or macos-14-large.

The macOS 12 runner image will remain latest until migration of the latest YAML workflow label to macOS 14 in Q2 FY24 (April – June 2024). While macOS 13 is now generally available under the macos-13 label, this image will not be migrated to latest. Following this announcement, macOS 11 runner image will begin deprecation immediately with retirement expected to complete by June 2024.

The full list of software available for all macOS runner images can be found here. If there is software you require that is not installed on the image, please create an issue in the runner-images repository.
