How to enable dark mode in macOS

With the macOS Mojave release, the dark mode feature has impressed Mac users worldwide. This time around, it not only darkens the lower menu bar like in previous versions, but also makes your applications- and practically every corner of your Mac- dark.

Although many users still prefer the lighter version, embracing the dark side can be somewhat refreshing and a great change for your eyes, especially if you are working in a shadowy environment.

Pros and Cons of Dark Mode

Before you proceed with switching to Dark Mode on your macOS, you might want to weigh the pros and cons to see if it’s worth it. We’ve elaborated on some of the points that we think our readers should take into consideration when it comes to Dark Mode.


  • It can potentially take some pressure off your eyes. This can be especially relevant if you happen to use your Mac during the night or when it’s dark. One of the main reasons Dark Mode is implemented in computers and mobile devices is to reduce eye strain.
  • It looks slick and appeals to a wide audience. Many people choose to use the Dark Mode feature simply because of the aesthetics and not much more than that. With so many Mojave macOS features, a quick switch to Dark Mode is definitely something you should try out.


  • 𐄂 Poor readability. While Dark Mode might seem like a great idea at first, reading bright characters on a dark background can be challenging for some people. So if you’re about to go through large chunks of texts, we would advise using a light theme instead.
  • 𐄂 It can drain the battery more quickly than usual. Although there are many arguments both for and against this statement, with a little research you will see that many users have reported their battery life taking a significant hit after switching to Dark Mode. The main reason for this is that LCD displays require more energy to produce black colors, whereas light colors are the easiest to produce.

Now you know both the good and bad sides of Dark Mode, we will show you step-by-step how you can easily switch it on when you need to.

How to enable Night Shift

Night Shift is another feature designed to reduce pressure on your eyes during evening hours.
