CI: remove macos13 #30571

tacaswell · 2025-09-16T19:54:40Z

The VM is being dropped by GH [1] on macOS is no longer supported by homebrew or Apple.

This job is starting to fail on installing homebrew dependencies. Rather than try to fix this, move on to the next image which we need to do by the end of the CY anyway.

This means we no longer are testing on intel macs.

Sounds reasonable. Should we move one of the other configs to macos-15?

These look real, I assume related to the recent changes in glib that we dealt with else where?

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

Checkout backport branch and update it.

git checkout v3.10.x
git pull

Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 22a9c55481c9e643612cae44c8146652d1a0ee10

You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #30571: CI: remove macos13'

Push to a named branch:

git push YOURFORK v3.10.x:auto-backport-of-pr-30571-on-v3.10.x

Create a PR against branch v3.10.x, I would have named this PR:

"Backport PR #30571 on branch v3.10.x (CI: remove macos13)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.

@tacaswell a belated response while researching my open issues: yep, that is a genuine error/failure that was occurring - it's reported as #29732 and seems to affect MacOS 14 too.

I hadn't managed to figure out how to resolve the problem; it began appearing from version v3.52.0 of the Python PyGObject library -- and I had a sense that some Brew/package selection tweaks might be the way to fix it, but without a suitable MacOS machine locally I explored as many attempts as I could think of and was unable to find a satisfying upgrade/resolution path.

Edit: attempt to rephrase for clarity.
