Re: Building python-based Mac app with py2app, creating an installer, generates failing installer

Thanks for your replies. I managed to come up with something that worked!

I had to do a couple of things, for those that are interested…

I needed to upgrade py2app to version 0.8, which fixed a problem in the version we were using (0.7.3) where file permissions were not preserved when copying files into the application bundle. As an aside, I tried the most recent version (0.14), but it created a new and different problem (which I can’t recall at the moment).
In the pkgbuild command, I had been using —root instead of —component when creating the component package from the application. Using —root made a package that expected to install its own python, which is why it was trying to mess with the /System Python.Framework directory. Using —component made things work. :)

Hope may this will help someone someday.

It's presumably not permitted due to the MacOS System Integrity Protection on `/System/`.
