Requesting the ability to test Mac OS images prior to full public release. Currently we only have images available with OS 26 + Xcode 27 beta. For example, Mac OS 27 (Golden Gate) is available as a beta right now from the Apple Downloads site. It would be helpful to be able to test this new OS + new Xcode versions against our pipelines to give us as much heads up as possible for any changes that may be necessary, prior to it being publicly released.
