Hi Ben and all,

thanks for the quick reply. In fact I am using two Qt versions - one for recent 
and one for older OSX. For the older ones I am using Qt5.9.2 and so far this 
had been working until now. Furthermore, I am compiling my app via qmake / make 
on the terminal and don't use XCode. In case you have further ideas please let 
me know.

Best

Alex
