The 10 Best New Features of macOS Mojave
1. Dark Mode
High Sierra allowed you to change your menu bar and Dock to a darker color scheme, but everything in-between stayed a little bright. To turn to the dark side in Mojave, click on the Apple logo at the upper-left corner of the screen and choose System Preferences. Here, select General, and under Appearance, click on Dark.
Your desktop background and Apple’s native apps such as Safari, Photos, Calendar, Xcode, and more will now feature darker colors and themes. This is much easier on the eyes, especially for people who spend a lot of time on their Mac. Colors in the Photos app also contrast better while in Dark Mode.
