Let's go for 10.6.
>From https://qt-project.org/doc/qt-5/macosx.html:
Mac OS X 10.7 "Lion" and 10.8 "Mountain Lion" are considered reference configurations, meaning they are tested by a continuous integration (CI) system. Qt 5 applications may be deployed to Mac OS X versions 10.6 "Snow Leopard", but support is limited.

If 10.6 support becomes difficult for some reason, we can dump it and make 10.7 the minimum supported version.
