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.
