Just to confirm - drag & drop is working on your Mac, but not when pyinstaller is used to make a package.

To be honest, I've never tested drag & drop with pyinstaller, and have had difficulties in the past on Mac to get it to work, due to missing libraries, etc...

Does it work without drag & drop, so if you just create a simple GUI?

Hi Richard Yes drag and drop works between apps ie finder to app when running from pycharm . Showcase.py runs after using Pyinstaller as an app on Mac . It’s only when drag and drop is implemented that I get the reported error Cheers Kevin On Tue, Oct 15, 2019 at 7:37 PM +0100, "Richard Jarvis" <[e-mail]> wrote: Just to confirm - drag & drop is working on your Mac, but not when pyinstaller is used to make a package.
