How to fix font rendering on non-retina displays with macOS Mojave

by John Anderson December 01, 2019

Do you think the fonts and screen text look blurry, fuzzy, or excessively thin in macOS Mojave? If so, it may be due to changes in smoothing in Mojave, especially for users with screens without retina. 

If you are running macOS Mojave on a Mac without a retina display, or with an external monitor that does not have an ultra-high-resolution display, you may have noticed that some fonts and text may appear as blurry or excessively thin. 

Fortunately, with a little effort, you can make some adjustments in the way that macOS Mojave handles font smoothing, which can improve the appearance of text and fonts on your Mac’s screen.


Things to Do:

Open a terminal and type the following command:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 1

After typing this command press ENTER, log out of your user and log in again. Upon entering again you will see that the fonts are slightly more readable.

If you still think it is not enough you can change that 1 of the end of the command to a 2 or 3 to apply more antialiasing to the source, 3 is the maximum value. Please see the examples below:


defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

defaults -currentHost write -globalDomain AppleFontSmoothing -int 3





On the other hand, if you want to return to the default fonts, just type the same command by assigning the value 0:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 0

Please note that you must log out and log in to your macOS user account for the changes to take effect.


How to enable font smoothing in macOS Mojave


  1. First, go to the Apple menu and select “System Preferences”
  2. Choose the “General” preferences panel and check the “Use font smoothing when available” box so that it is enabled (or disabled).
