Questions tagged [macos-darkmode]

Dark Mode is a feature introduced in macOS Yosemite that changes the primary color scheme of the operating system to one that features light text on dark backgrounds instead of the traditional dark text on light backgrounds. Use this tag for questions specifically related to detection and issues stemming from the use of Dark Mode on macOS as opposed to general light-on-dark color scheme questions.

First introduced in macOS Yosemite and further refined in macOS Mojave, Dark Mode enables uses to toggle the environment design of the operating system to a color scheme that features light text on dark backgrounds as opposed to dark text on light backgrounds.

Apple describes this as "a dramatic new look that's easy on your eyes and helps you focus on your work."

Modern software can detect the presence and use of Dark Mode to allow developers to display their software in a design that matches the aesthetics of other Dark Mode apps.
