Azure Pipelines Now Supports Additional Hosted macOS Versions

This post announces that Azure Pipelines will continue to support and maintain the High Sierra image for hosted macOS agents, in addition to the previously announced upgrade to OS X 10.14 (Mojave). This allows teams to build with older Xcode versions on High Sierra or to run automated tests on High Sierra after building on Mojave. The post provides YAML snippets and UI instructions for selecting the desired macOS version ('macOS-10.14', 'macOS-10.13', or 'macOS-latest'). It also mentions ongoing efforts to keep macOS build agents up-to-date with the latest Apple ecosystem releases and to update other tools on the agents.
