It looks the problem is in your Distribution.plist; change the 
hostArchitectures to "arm64,x86_64".  Otherwise, the macOS installer assumes 
your app can only run as an Intel binary.

I can’t check right now (I don’t have a universal Python installed, just to 
separate intel and M1 pythons), but if you use Finder “Get Info” on the 
application bundle: does it show the “Open using Rosetta” checkbox?

If it does: ensure it is unchecked.

[Pythonmac-SIG] Universal build launches as Intel on M1

[Aivar Annamaa]

Hi!

I have an app bundle, with embedded python.org's universal build of Python
3.10.2 framework and a Tkinter-based GUI (
https://github.com/thonny/thonny/releases/tag/v4.0.0b1)

I've used IDLE's approach in the Info.plist, and the launcher script.
Functionally all is working fine, but a M1 user reported, that when opened
from Finder, the app is launched in "Intel" mode. When the launcher is
invoked in Terminal (/Applications/Thonny.app/Contents/MacOS/thonny), the
app gets run in AMD64 mode. I don't have a M1 myself, so I haven't
reproduced it myself.

The same user now said that latest IDLE (3.10.4) runs in AMD64 mode even
when launched from Finder.

Any ideas what to check or try in order to make my app run in native mode?

My launcher script template is here:
https://github.com/thonny/thonny/blob/master/packaging/mac/Thonny.app.initial_template/Contents/MacOS/thonny
(shebang becomes gets set
to 
.../Thonny.app/Contents/Frameworks/Python.framework/Versions/3.10/Resources/Python.app/Contents/MacOS/Python
by the postinstall script)

Info.plist template is here:
https://github.com/thonny/thonny/blob/master/packaging/mac/Thonny.app.initial_template/Contents/Info.plist

Best regards,
Aivar
