Hello @erik-bershel - what is behind the decision for an ARM-based Mac not to be available for Azure DevOps?

[erik-bershel]

Hey @kober32!

Unfortunately, I can't answer this question. We don't make decisions like that in this repo. I recommend contacting Azure DevOps support for information on product development plans.

@kober32

I should also note that as soon as information about support reaches us, we will share this news here:

• Add macOS-13 (arm64) & macOS-14 (arm64) & macOS-15 (arm) Image to Azure Pipelines #8971

Hello @erik-bershel - what is behind the decision for an ARM-based Mac not to be available for Azure DevOps?

Apparently it is due to billing compatibility -> https://learn.microsoft.com/en-us/azure/devops/release-notes/roadmap/macos-agents-apple-silicon. It's in the 2025 Q2 roadmap https://learn.microsoft.com/en-us/azure/devops/release-notes/features-timeline.

[kober32]

@xernaj Oh, thanks for the link! That's good news, hope it won't be delayed...

[erik-bershel]

Hey @xernaj!
Unfortunately I don't have full details on the timeline and reasons - I can only confirm that billing was an initial sticking point, which was publicly announced and planned to resolve by the Azure DevOps team.

Heads up! 👋

GA postponed to March 18th due to the current issue with image performance: #11509 😞

#11509

@erik-bershel This may or may not be related to the performance issues, but hoping that this Voiceover automation issue will also be resolved in the upcoming MacOS 15 release? #11257

[erik-bershel]

Hey @ChrisC!

We'll fix it with the next releases. Hopefully before GA.

[YashikKhunt]

if I use macos-latest for my runner will it be use macos-15 after it available or it should be macos-15 to use it ?

[erik-bershel]

Hey @YashikKhunt!

List of default labels available here and here.

In general macos-latest now targets macOS 14 based images.

Heads up! 👋

GA postponed to April 8th due to the current issue with image performance: #11509 😞

can you unlock that issue so people can comment? https://www.apple.com/mac/compare last intel mac was from 2020 (and they are not selling intel based hardware any longer)

@erik-bershel - When will macOS 15 be the applicable version for macos-latest? Getting some warnings back from Apple indicating we need to build our app with xCode 16 or higher by April 24th. Obviously there are other ways to go about using xCode 16 or higher, but would like to continue to use macos-latest to keep up to date with Apple's requirements if possible.

[erik-bershel]

When will macOS 15 be the applicable version for macos-latest?

I can't say for sure right now. It will take some time. Probably not before summer. In any case, we will notify the community in all available ways.
