Walkthrough

The macOS CI workflow has been narrowed to remove macOS 13 from the build matrix, retaining only macOS 14. This reduces the number of concurrent CI builds without modifying any workflow logic or steps.

🐰 One version gone, the matrix shrinks,
macOS 14 alone now links,
Fewer builds, same rabbit speed,
Streamlined CI is all we need! 🚀

19-26: LGTM! Removal of deprecated macos-13 runner is correct.

The macOS 13 runner image was retired by December 4th, 2025, and the images are now fully unsupported. GitHub Actions started the deprecation process for macOS 13 and macOS 13 arm64.

Migrating to macos-14 is a valid approach. As an optional enhancement, you might consider expanding the matrix to include macos-15 (or macos-latest) to ensure broader compatibility testing, since workflows that are architecture agnostic are encouraged to transition to arm64 labels such as macos-15, macos-latest, or macos-14.

💡 Optional: Expand matrix to include macos-15

     strategy:
       matrix:
         cxxstd: ["17"]
-        os: [macos-14]
+        os: [macos-14, macos-15]
         include:
           - platform_file: include $(ACE_ROOT)/include/makeinclude/platform_macosx.GNU
