pyenv built executables might not be backwards portable, e.g. executable created on macOS 13 cannot be run on macOS 12

Hi - I’m unable to find a reference to this in the Nuitka issues nor documentation, but apologies if I missed it and feel free to point me at it.

When creating an executable on (example) macOS 13 Ventura, I cannot run it on any version below, for example on macOS 12 Monterey - getting:

You can't use this version of the application ... with this version of macOS. You have macOS 12.5.1. This application requires macOS 13.0 or later.

Is this an option that can be tweaked within Nuitka? Or does this simply come down to a limitation when compiling anything on macOS?

Appreciate any guidance, thank you.

I have had success building with support for macOS 10.9 on macOS 12. I did use a custom built version of python and I made sure to always have -mmacosx-version-min=10.9 in CFLAGS, CXXFLAGS and LDFLAGS while building python and my app using Nuitka. It is likely that you will not need to compile python from source and just a version from python.org will suffice. Depending on how far back you want to support you might need to go with an Intel-only python if you want to support older than 11 if I recall. In any case it is not recommended to use the version of python that comes with your macOS install.

Please make sure to post the output of python -m nuitka --version if you would like further assistance.

You would have to configure your pyenv to build binaries for older macOS, or build it on old macOS. For what I know, it is not intended for deploying applications. Instead use CPython, which is the one listed as supported in the manual. Using pyenv on older macOS will probably make it work on that or higher, but e.g. CPython allows 10.9 or higher for deployment. And you can build on new macOS, you just have to pick the intel arch during build.
