Great to hear that.

That is intentional. The setup.py for the package pyobjc calculates the “install_requires” list at runtime to ensure it will only install framework wrappers for frameworks that are actually present.  It might be possible to use conditional dependencies for that (see [1]), but I haven’t checked yet if those compare version numbers as structured data or strings.  PEP 426 seems to indicate they are just strings, and that would be less useful.   

I guess a wheel for the “pyobjc” package could just depend on all framework wrappers, that would install some code that isn’t relevant for the current machine but wouldn’t result in install failures (which could happen when installing all framework wrappers from source).
