1. Go Dark
Dark mode is available on pretty much every app and device these days, and of course, you can enable the setting on Windows and macOS, too. On macOS, open up System Preferences and then choose General and either Light, Dark, or Auto—that last one changes the setting based on the time of day in your location.
If you’re on Windows, open up the Settings panel and pick Personalization, Colors, and then click the Choose your color drop-down to see the options. In addition to Light and Dark, there’s a Custom option that lets you pick separate settings for apps and Windows itself.
