# Mac OS Ventura use the following with XCode 14

As of Qt6 and later there is one final step required.
Qt's macdeployqt does not properly add the rpaths needed for the 
Qt plugins to find the Qt Frameworks when embedded
inside an app even one using the specified Qt app layout.

These installed Qt plugins need to have an specific @loader_path rpath added
as follows:
