macOS-latest workflows will use macOS-12

[ddobranic]

Breaking changes

macOS-12 is ready to be the default version for the "macos-latest" label in GitHub Actions and Azure DevOps.

Target date

This change will be rolled out over a period of several weeks beginning on October, 3. We plan to complete the migration by March, 1st, 2023.

The motivation for the changes

GitHub Actions and Azure DevOps have supported macOS-12 in public beta since April 2022, and starting from June 2022 macOS-12 is generally available for all customers. We have monitored customer feedback to improve the macOS-12 image stability and now we are ready to set it as the latest.

Possible impact

The macOS-12 image has a different set of software than macOS-11. The most significant changes are listed in the table below:

Tool name	macOS-11	macOS-12	Notes
Virtualbox Vagrant Support for Parallels Desktop	-	6.* 2.* 18.*	At the request of users, virtualization tools that were previously unavailable in macOS 11 had been added
Ruby toolcache	2.4.* 2.5.* 2.6.* 2.7.* default 3.0.* 3.1.*	2.7.* 3.0.* default 3.1.*	EOL Ruby versions had been removed
Ruby Gems	xcode-install, cocoapods, nomad-cli, xcpretty, bundler, fastlane, jazzy	xcode-install, cocoapods, xcpretty, bundler, fastlane, jazzy	nomad-cli has been removed as the project is no longer maintained.
CLang	13.0 (default)	14.0 (default)	Please, pay attention to changes for default compiler
GCC / GFortran	9.* 10.* 11.*	11.*	Old versions had been removed
Xamarin.iOS	13.20 - 15.8	15.0 - 16.0	Old versions and versions incompatible with the pre-installed Xcodes had been removed

I heard the news. Is there any new methods for these? These just got deprecated and it led me to this GitHub page. I will need to fix this as soon as possible if the new methods are found.

@arichorn Please see this blog post

[ddobranic]

Thank you @wojsmol

[arichornlover]

Alright but I already went to this site earlier today, it is a little complicated to understand GitHub’s new commands

@arichorn Please post a link to affected workflow if you can.

@arichorn - It would seem they forgot to include the name of the offending action into the warning message, so it can be quite cryptic. Re-run a job that shows the warning and check the box for debug logging, then you can see in the debug output which actions need to be updated.

(Also - those are unrelated to this particular issue.)

Oh alright thanks, and sorry for putting it in here

Hey I’m back! I have successfully migrated the runner to run MacOS 12 actions, I readed the thing above and resolved it! Ty y’all

I just found even I use macos-latest it still runs on v11 instead of v12 in this https://github.com/NEO-TAT/tat_flutter/actions/runs/3260016715/jobs/5353264229.

But if I changed it to macos-12, it uses 12.

Maybe it still need some times to migrate (?

@Xanonymous-GitHub hello, yes migration is in progress and it is planned to be complete by December 1st.

Got it, thanks :)

Hey guys,

I understand that you have time pressures, and it's great to see the amazing work you are doing.

However, for the least six months, we have not been able to do a build using the runner.

We need to support Swift 5.7, and Xcode 14. However, it took six months for this runner to even support the latest Xcode/macOS.

Mac OS do YEARLY updates to their tooling. Having this run 6 months behind really is detrimental to delivery.

I could understand 1 month, but 6 month delays... While there has been a BETA out for even longer. Sounds like the Mac team needs to grow a few team members.

Thanks for the great work again, and hopefully we won't have to wait 6 months + for an update to the Xcode/macOS runners.

Finally migrated: #6901!
