actions/runner-images deprecating macos-12

[2bndy5]

Bug Description

I just came across this warning in my CI workflow's summary (originating from job that builds x86_64 target on macos-12):

A brownout will take place on November 4, 14:00 UTC - November 5, 00:00 UTC to raise awareness of the upcoming macOS-12 environment removal. For more details, see actions/runner-images#10721

So, I was wondering if it is ok to migrate to macos-14 instead? I don't own a Mac to test/build locally.

Your maturin version (maturin --version)

Your Python version (python -V)

whatever is setup in runner's tool cache (using python-version: 3.x)

What bindings you're using

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. Run maturin generate-ci on existing project or maturin new <pkg-name>
2. Push generated workflow to GitHub remote

#2246

[2bndy5]

Oh I didn't see that PR. For the record, I did do a 'macos' search on open/closed issues/discussions. I didn't think to check PRs though. Glad to see you folks are already tracking it. I guess I'll leave this open since it will auto-close when #2246 is merged.
