Looks like the x86 mac-os build is failing because of an outdated MacOS version.

Yeah, looks like it went out of date precisely 4 days ago, and homebrew is not gonna take any shit about it.

I guess it would be kind of nice to still have one test on the pre-Arm architecture, so I'll see if there's a flag I can pass to disable the hard error. But maybe we should just go ahead and step to macos14 and 15 instead of 13 and 14.

Ah, maybe you can still get non-Arm on later versions. At any rate, I'll simply upgrade, since the alternatives look bad.

Upgrading sounds good.

We can stick with macos-latest and drop the matrix for 14. It looks like the x86 builds are being deprecated in Github actions support: https://docs.github.com/en/actions/how-tos/write-workflows/choose-where-workflows-run/choose-the-runner-for-a-job#standard-github-hosted-runners-for-public-repositories

I will update the Github required actions once the yaml is updated.
