Worked on stabilizing macOS builds for the nextcloud/craft-blueprints-kde repository by addressing a crash related to OpenTimelineIO integration. The solution involved reverting to a built-in static version of OpenTimelineIO specifically for macOS, using conditional logic within the build system configuration to ensure the static library was only applied on that platform. This approach maintained consistent behavior across other platforms while improving reliability and reducing crash risk for macOS users. The work was implemented using Python and focused on build system configuration and dependency management, resulting in a more stable build process without introducing changes to the core application functionality.
