During January 2025, Horo focused on stabilizing macOS builds for the denoland/chromium_build repository by addressing a recurring failure in the Apple linker integration. Using Python and Shell scripting within established build systems and CI/CD pipelines, Horo reverted the solink step in apple/linker_driver.py, removing the object_path_lto action and related logic. This rollback restored build reliability and improved CI throughput for macOS, ensuring uninterrupted pull request validation and supporting ongoing cross-platform development. Horo also documented the changes and rationale for future maintainers, demonstrating a methodical approach to troubleshooting and maintaining the integrity of complex build environments.
