Worked on enhancing error reporting for native library loading on macOS within the Unity-Technologies/mono repository. Focused on improving diagnostics by modifying core loading paths in C to accept and propagate a load_error parameter, enabling more precise user-facing messages when native bundles fail to load, particularly in cases involving unsigned libraries. Leveraged skills in error handling and native libraries to centralize error management, which streamlined troubleshooting and reduced support overhead. The update improved maintainability by documenting error propagation and clarifying failure points, ultimately making macOS development workflows more reliable for users integrating native libraries into their Unity projects.
