I see the Github Page for Python Mac App Store.
It looks like you have solved all of the technical challenges, congratulations!
I notice you have not specified a license file, which I believe is an obstacle to deploying Qt without buying a $1000+ Qt Commercial license.
In fact if you go to https://www.qt.io/product/features and select MacOS as your deployment platform, it greys out nearly everything, no matter what license you select. )
Did you actually get this app published on the App Store? If so, can you provide a link to the App Store? (preferably on the GitHub Readme).
Alright, Nice Work, and thank you for sharing it!
