backward compatibility

Hello all,

I have a desktop application which I developed with the Qt framework. In terms of backward compatibility on OSX I have a problem: The app is compiled on 10.15 and works fine on 10.15 and 10.14. This binary also launches with 10.13 but at some point throws an errors about missing symbols in libSystem.B.dylib

Can anyone explain me how to approach this issue ?

Thanks in advance,
best

Alex

I could figure: The PRO-File has to contain:

QMAKEMACOSXDEPLOYMENT_TARGET=10.13
