PyInstall：runs normally on my Mac，but on other Mac unable to open

[hezudao]

Environment: Python 3.8.8 , PyInstaller 4.3

The app file runs normally on my Mac. If it is opened on other Macs, it will prompt that the document "main. App" cannot be opened. The text encoding "Unicode (UTF-8)" is not applicable. The file may have been stored with a different file encoding, or it may not be a text file.

I could be way off here, but I was under the impression that with the introduction of Catalina, an Apple notarization was necessary even for sharing apps from one computer to another, even if this was not done through the Apple Store. I encountered the same problem in August 2020 when creating an app with py2app and sharing it with someone else.
