If you prefer darker backgrounds to lighter ones, you can enable the Dark Mode setting on your MacBook. This feature not only adjusts your device’s appearance by switching many of the border and page colors from lighter to darker in supported applications, but your MacBook’s Dock, menu bar, and sidebars will also switch to Dark Mode.
To enable Dark Mode, simply head to System Settings and select Appearance from the sidebar. Now, you’ll see three different options next to Appearance: Light, Dark, and Auto. Finally, choose either Dark or Auto. The latter choice will automatically switch your MacBook’s colors between Dark and Light Mode depending on the time of the day.
On the same settings page, you can also change the Accent and Highlight colors, which are essentially the color of buttons, menus, and the text when highlighted. By default, MacBooks ship with a Multicolor accent. All you need to do is pick one of the color options next to Accent color: Blue, Purple, Pink, Red, Orange, Yellow, Green, and Graphite. Your Highlight color will automatically be changed to your Accent color. However, you can change that by expanding the dropdown menu and picking a color of your choice.
