PyInstaller Executable Producing Unexpected Loop Output on Mac M1

[Rapid1898-code]

i try to run the following code on my computers:

from yahooquery import Ticker
inpStocks = ["a", "b", "c", "d", "e", "f"]  
for rowNum, stock in enumerate(inpStocks):
  print (f"Read data for {stock} in row {rowNum}...")
  yqData = Ticker(stock)
  if stock not in yqData.price:
    print("Stock not in price-info")

I am creating an executable program using pyinstaller with this command:

pyinstaller --onefile test.py

When i run this python-code directly (on Windows or Mac) and also the executable program on Windows i get an output as expected in that way:

(3_10) C:\DEVNEU\Fiverr2025\ORDER\VanaromHuot>python test.py     
Read data for a in row 0...
Read data for b in row 1...
Read data for c in row 2...
Read data for d in row 3...
Read data for e in row 4...
Read data for f in row 5...

But when i run the executable program on Mac i get a weird output in that way

Why is this not working on Mac with the excecutable?
Why is even such an output possible when you have a look at the for-loop in the code...?
Has this probably something to do that my Mac has a M1 chipset? (Mac Mini 2020 M1)
How can i run the above program on a M1 chipset if this is the problem?

Is yahooquery using multiprocessing behind-the-scenes? If that's the case, you should take a look at https://pyinstaller.org/en/stable/common-issues-and-pitfalls.html#multi-processing

You can also add print(sys.argv) at the very start of your program to see if executable is invoked multiple times and if the arguments correspond to attempts at spawning multiprocessing helper sub-processes.

I tried the print(sys.argv) statement as you mentioned -

When running on windows (python and exe) and on mac (python) i get this output:

(3_10) C:\DEVNEU\Fiverr2025\ORDER\VanaromHuot>python test.py
['test.py']
Read data for a in row 0...
Read data for sdjhaklsdjfks in row 1...
Read data for c in row 2...
Read data for d in row 3...
Read data for e in row 4...
Read data for f in row 5...

On mac (with created program) i get this output:

What can i do now

Read the link that I gave you in previous comment.

[Rapid1898-code]

Hello - i think using this code its working now -

from multiprocessing import freeze_support
freeze_support()

from yahooquery import Ticker
import time
import sys
print(sys.argv)
inpStocks = ["a", "sdjhaklsdjfks", "c", "d", "e", "f"]  
for rowNum, stock in enumerate(inpStocks):
  print (f"Read data for {stock} in row {rowNum}...")
  yqData = Ticker(stock)  
  if stock not in yqData.price:
    print("Stock not in price-info")

I get this output now:
