Installing and validating fonts on a Mac

Tags mac how-to

To use fonts in your apps, you need to install the fonts using Font Book. When you’re installing fonts, Font Book lists any problems it finds for you to review. You can also validate fonts later on.


Install fonts for use across the system with the included Font Book app.


  1. Launch the Font Book application located in your Applications folder.
  2. With Font Book open click the Add + button in the Font Book toolbar.
  3. Locate and select the font, then click Open.
  4. Font Book will both install and validate the font upon import and give a list of any fonts that fail validation.

Additional notes

To quickly install a font, you can also drag the font file to the Font Book app icon, or double-click the font file in the Finder, then click Install Font in the dialog that appears.

When you install a font, it’s automatically validated or checked for errors. You can also validate fonts after installation if the font isn’t displayed correctly or if a document won’t open because of a corrupt font.

Installing too many fonts can slow some apps down, and cause stability issues. If you're planning on using a high number of fonts a third-party font management client is recommended.
