Since its launch, I’ve been using Dark Mode on macOS Mojave. Whilst it took some getting used to (I struggled with Apple Mail at first), it’s particularly useful when you’re staring at a screen for a large portion of the day.

However, there’s one app I prefer to use in Light Mode, and that’s Microsoft Word. Is there a way to use Dark Mode on macOS Mojave and choose specific apps to use in Light Mode? Yes, but you have to go via the Terminal.

First of all, you need to get the bundle identifier of the application. Enter the following command in the terminal:
osascript -e 'id of app "Microsoft Word"'

This should return a value such as:

Following this, you then need to set Microsoft Word to use Light Mode:
defaults write NSRequiresAquaSystemAppearance -bool yes

Restart Microsoft Word, and it should now be running using Light Mode, whilst the rest of the OS remains in Dark Mode.
