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.

When building using QMake from command line, you can use e.g.

    qmake QMAKE_MACOSX_DEPLOYMENT_TARGET=10.12

to set the deployment target version.

Remember to check the supported target versions for the Qt you're using:

- Qt 5.12: https://doc.qt.io/qt-5.12/macos.html#supported-versions
- Qt 5.14: https://doc.qt.io/qt-5.14/macos.html#supported-versions
- Qt 5.15: https://doc.qt.io/qt-5.15/macos.html#supported-versions

In short: The minimum for Qt 5.12 is macOS 10.12, while for Qt 5.14
and Qt 5.15 it's macOS 10.13.

I'm not sure what the minimum for Qt 5.9 was, but I believe it may
have been macOS 10.10.

Cheers,
Elvis

You can’t set it to be any earlier than the Qt version you are running against, however, or precisely this sort of thing will happen.  If you need to run on older OS X versions, you need to make sure the Qt version you’re using is compatible with those older versions.  (I forget where this information is, but Google always finds it for me.  :->)
