On OS X Yosemite using a PyInstaller packaged app looking like this:

#!/usr/bin/env python
from plyer import filechooser

print(filechooser.choose_dir())

I get:

Traceback (most recent call last):

IndexError: list index out of range

Did I maybe miss to package a library?

I just ran in to the same issue when using pyobjus together with rumps (no PyInstaller involved):

import rumps
from pyobjus import autoclass

NSString = autoclass('NSString')
text = NSString.alloc().initWithUTF8String_('Hello world')
print text.UTF8String()

  File "./issue-21.py", line 6, in <module>
    text = NSString.alloc().initWithUTF8String_('Hello world')

I don't see this on current pyobjus, so it may have been fixed since then. Could you perhaps try with a recent pyobjus and let me know if we can close this?

[Julian-O]

Closing as presumed fix. Did not hear back from OP.

Hello @Julian-O! I wanted to let you know that it appears that this is now an issue again on macOS Sequoia (15.0) on my M3 pro Macbook Pro. I found this GitHub issue subsequently to doing a similar thing as OP. I can reproduce the error with the above code (using the latest version of plyer, and pyobjus):

@macarooni-man Ditto, https://github.com/kivy/pyobjus/pull/89 seems to be already in place which fixes this issue.

Update: tested this pull makes it work on 15.0 and before.
