This package allows to detect if macOS 10.14+ is running with the Dark Mode enabled. The main application of this package is to detect the Dark mode from your GUI Python application (Tkinter/wx/pyqt/qt for python (pyside)/...) and apply the needed adjustments to your interface. Darkdetect is particularly useful if your GUI library does not provide a public API for this detection (I am looking at you, Qt). In addition, this package does not depend on other modules or packages that are not already included in standard Python distributions.


import darkdetect

>>> darkdetect.theme()

>>> darkdetect.isDark()

>>> darkdetect.isLight()

It's that easy.


The preferred channel is PyPI:

pip install darkdetect

Alternatively, you are free to vendor directly a copy of Darkdetect in your app. Further information on vendoring can be found here.

  • This package can be installed on any operative system, but it will always return None unless executed on macOS 10.14 Mojave or newer versions. This package is designed to work also with older versions of macOS and in those cases it will also return None. Detection of the dark menu bar and dock option (available from 10.10) is not supported.
