Azure DevOps is starting the deprecation process for the macOS-12 (Monterey) hosted pilelines image. While the image is being deprecated, you may experience longer queue times during peak usage hours. Deprecation will begin on October 7 and the image will be fully unsupported by December 3. Pipeline jobs using the macOS-12 image label should be updated to use macOS-latest, macOS-13 or macOS-14.

To raise awareness of the upcoming removal, we will temporarily fail jobs using macOS-12. Pipeline jobs that are scheduled to run during the brownout periods will fail. The brownouts are scheduled for the following dates and times:

• November 4, 14:00 UTC – November 5, 00:00 UTC
• November 11, 14:00 UTC – November 12, 00:00 UTC
• November 18, 14:00 UTC – November 19, 00:00 UTC
• November 25, 14:00 UTC – November 26, 00:00 UTC

The macos-latest Hosted pipelines agent image now uses macOS-14 (Sonoma).
