[Rapid1898-code]

Hello - i create an executable on my Mac computer -

when i want to run the executable on my older Mac

i get this error message:

PolziMacs-Mini:~ polzimac$ /Users/polzimac/Downloads/stockMA6_TrialNEW/stockMA6 ; exit;
-bash: /Users/polzimac/Downloads/stockMA6_TrialNEW/stockMA6: Bad CPU type in executable
logout

How can i create an executable on my M1 Mac which can be also run on older Macs?

If you want the program to run on x86_64 machines, you need to create either x86_64 build, or a universal2 one. You have made an arm64 build, which cannot run on a x86_64 machine for obvious reasons.

If you want to create x86_64 build on M1 Mac, you need to install either x86_64 python or universal2 python, and run it in x86_64 mode. Then use that to create x86_64 virtual environment, install dependencies and PyInstaller in it, and it will create an x86_64 build by default.

If you can ensure that both your python and all non-pure-python dependencies are universal2, you can create a universal2 build instead.

See https://pyinstaller.org/en/stable/feature-notes.html#macos-multi-arch-support

Thx for the fast response -
So when i use universal2-python i can create an executable on my M1 which is working on M1 Macs and also older Macs when i use my standard way for create like

pyinstaller --onefile xzy.py

Correct?

As per the link I gave you earlier, you need to explicitly enable universal2 build via --target-architecture option. And you need to ensure that all non-pure-python packages provide universal2 binaries, otherwise you'll get errors during build, as also described there.

Thanks - with the following command i was able to create a working exectuable on my M1-Mac for an older Intel-Mac:

pyinstaller --onefile --target-architecture x86_64 test3.py

and with this command i am able to create an exectuable on my M1-Mac whichs runs on the same machine

pyinstaller --onefile test3.py
