Issue:
Update MacOS builds
The GHA list of [supported versions](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources) no longer includes MacOS 10.15, which is causing our builds to hang waiting for runners that no longer exist. We need to update to at least `macos-11` to resolve this.
