Build for older version of MacOS?

[Bubba8291]

Hi. One of my macs has 10.14. When I try to run the app from terminal, it gives this message.

[31557] LOADER: Cleaning up Python interpreter.```

Additionally, building it fails due to `pyside` not having all the dependencies available.

Can you allow the release to support 10.14?

Hey @Bubba8291 👋🏻

Thanks for your interest in swiftGuard!

I can't fix that for you, because we use Qt6 ( PySide6) as Gui framework, and it enforces minimum macOS 10.4 ...
So maybe you can change PySide6 to PySide2 in all imports in the source code and try then compiling using the build script.

In the future, it may be possible for me to compile swiftGuard for older macOS, and push it as seperate release 🚀
