This targeted bug fix improved system reliability for users on the latest macOS beta, particularly in complex display environments. Demonstrated expertise in Objective-C and macOS development, with careful attention to version-aware condition handling and maintainable code practices. The work prioritized system stability over new features, enhancing the user experience for macOS beta testers.
