What you need to do

(Recommended) If your workflow is architecture agnostic, you can migrate to any of our arm64 labels:
– macos-15 or macos-latest
– macos-14
– macos-14-xlarge
– macos-latest-xlarge or macos-15-xlarge

For users that require the x86_64 (Intel) architecture, we have added a new label to support standard runner users. Jobs can be migrated to one of the following labels:
– macos-15-intel (new)
– macos-14-large
– macos-latest-large or macos-15-large

For more information, please visit the runner images repository.

Notice of macOS x86_64 (Intel) architecture deprecation

Apple has discontinued support for the x86_64 (Intel) architecture. GitHub will no longer support this architecture on macOS after the macOS 15 runner image is retired in Fall 2027. You should begin migrating your workloads to arm64-based (Apple Silicon) runners as soon as possible to prepare for this eventual deprecation.
