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.
