Hi here, Since that DevOps Azure will not support macOS 10.14 as of December 10, it's worth considering bump the version to 10.15. Otherwise, we may get a broken check again for PRs.
> The macOS-10.14 environment is deprecated and will be removed on December 10, > 2021. For more details see > https://devblogs.microsoft.com/devops/hosted-pipelines-image-deprecation/
