Yosemite Guide

Helvetica Neue typeface replaces Lucida Grande as the system font in OS X Yosemite

One of the most striking changes that you will notice when you first fire up OS X Yosemite is the system-wide font change. Apple’s previous desktop operating system releases, since 1999, used Lucida Grande as the system font.

Lucida Grande worked well on lower resolution screens, but as high resolution Retina Displays become more common, it’s starting to look out of place. To address the issue, Apple decided to adopt iOS’ system font of choice—Helvetica Neue—and make it the system font for OS X Yosemite.
