MacOS Mojave brought with it a slew of new features, the most striking of which is a system-wide dark mode that applies to all native Apple apps and compliments Apple's Night Shift to ease your eyes late at night.
How to turn dark fashion
The option for Dark mode is in the System Preferences app, which you can open from the Dock, your Applications folder, or by clicking the Apple icon at the top of your screen and select “System Preferences.” When you're there, click on “General.”
At the top of the window, you'll see the toggle between light mode and dark mode.
There is another feature to set here: the accent color. This will determine the color of buttons and any highlights in native apps. Surprisingly, setting the accent color to "Graphite," the gray color, makes dark mode slightly darker. It changes from a bluish-gray to a flat gray color which you may prefer.
Night shift changes the color of your display to seem warmer (more orange) at nighttime since prolonged exposure to blue light can strain your eyes.
Under the "Night Shift" tab, you'll find an option to enable it from Sunset to Sunrise. System preferences night shift ” width=”650″ height=”300″ src=”/pagespeed_static/1.JiBnMqyl6S.gif” onload=”pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);” onerror=”this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);”/>
Apple didn't invent Night Shift though. It actually comes from an old app called f.lux, which is designed to do the same thing. f.lux is still being updated and has more features and controls than Apple's built-in option, including the ability to set two different levels for Sunset and Bedtime.
If you d like to use f.lux instead of night shift, free to download, and works on any OS
