In this lesson for macOS Mojave, I look at the new Dark appearance that was introduced with macOS Mojave. Earlier versions of macOS do not have this feature. In older versions of macOS’s, you could only select the highlight color and not the overall appearance of your Mac. With macOS Mojave, Apple introduced the new Dark Appearance.
Enabling the Dark Appearance
To enable the dark appearance, you need to go to your System Preferences. From there select the General pane. The first option you’ll see is Appearance with two options – Light and Dark.
Use Dark Background for Messages Option
When you are using the dark appearance, the entire Mac interface switches to a darker appearance including your Mail Messages. If you prefer to read and write your messages on the lighter background, you can enable this in Mail Preferences. Just open your Mail Preferences (under Mail in the menu bar when Mail is open). Then select the Viewing Tab. You’ll see an option for using the dark background for messages. Just deselect this to use the lighter background for reading and writing messages in Mail. This option only shows when you are using the dark appearance.
