Currently it is not possible to configure a list of images that can be used in GitLab-CI, as it is possible on GitLab runner docker and Kubernetes executors.
I think this feature could be useful because macOS images are huge, and downloading them locally can take some time.
Additionally, it could add controls on which image is used and from which registry.
I can provide a pull request based on what it is done in GitLab runner code if you agree.

Thanks for your feedback.
