[chirp_devel] py3 File Open problem

You shouldn't need (nor be using) XQuartz for this. If you have wxWidgets installed, then it uses native Cocoa widgetry. So, maybe first: how are you installing wx? Can you try one of the .app builds to see if they behave differently for you?

Cool!

No such problem here, FWIW. MacOS 12.6.1, python 3.10.8 from brew. Also no problem with the build .app, which bundles 3.8 from Apple themselves.

PosixPath comes from pathlib:

> >>> import pathlib

> <class 'pathlib.PosixPath'>

But I don't think you should be seeing it in this section of code, unless there's some confusion between chirp's platform module and the python one. Not sure how or why you're seeing that though.

Because of the XQuartz requirement, I'm suspecting that maybe you have some very weird combination of things going on.

I think this should really be all you need:

Maybe consider what differs in your environment from that? The build system that generates the .app (which requires no XQuartz) pretty much just does that and then creates the bundle.
