In October 2025, John Beshay focused on stabilizing the macOS build process for the facebookincubator/cinderx repository by addressing a compatibility issue between Boost 1.89 and Homebrew. He resolved a critical build failure by temporarily modifying the build system configuration, specifically commenting out the Boost entry in the Homebrew section, which allowed the build to proceed. After confirming the dependency was required for the query-paths step, he reverted the change and began planning a more robust Boost dependency strategy. John’s work, leveraging Shell scripting and CI/CD expertise, improved cross-platform build reliability and maintained project momentum for future feature development.
