Breaking changes
macOS-11 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 September, 15. We plan to complete the migration by November, 3 December, 13 January 14.
The motivation for the changes
GitHub Actions and Azure DevOps have supported macOS-11 in preview mode since October 2020, and starting from August 2021 macOS-11 is generally available for all customers. For almost a year we have monitored customer feedback to improve the macOS-11 image stability and now we are ready to set it as the latest.
Possible impact
The macOS-11 image has a different set of software than macOS-10.15. The most significant changes are listed in the table below:
| Tool name |
macOS-10.15 |
macOS-11 |

| R lang |

R was not available for Big Sur when we prepared the image for the first time. Please use standard tool request process if the tool needs to be added |
| Virtualbox and Vagrant |
6.* and 2.* |

Virtualbox on macOS 11 requires security preferences changes, which can't be easily done. The PR with virtualbox is not yet merged #4010 |
