I have an app written on python + PyQt5. When I'm launching it from source it uses MacOS system appearance -- light colors for light appearance and dark for dark. But when I build the app using Pyinstaller it ignores system styles completely, and always use light color mode. How can I automatically apply system styles to my widgets, or at least detect system appearance and do it manually? Thank you in advance.

  • I'm not sure about mac but copying all plugins dir from `/site-packages\PyQt5\Qt\plugins` to `/bincache01_py37_64bit\pyqt5\qt\plugins` fixed the similar problem for me. Also disable `upx` when building the app. – Masoud Rahimi Jun 21 '19 at 10:44
  • eyllanesc, thank you for your answer! Now I can, at least, detect dark mode and deal with CSS and pallets. M.R., I don't have directory "Qt" in PyQt5, and directory "bincache..." at Pyinstaller dir. Maybe, it is platform-specific? – Ivan Budnikov Jun 27 '19 at 07:10
