The functionality of the module has been incorporated into other parts of Qt, or in some cases removed due to being obsolete or better suited as cross platform APIs.
For more details, see QTBUG-93629 in the Qt issue tracker.
To learn more about how to port from QtMacExtras to alternative APIs please visit the Qt 6 porting guide.
