Lucida Grande

As of OS X Yosemite (version 10.10), the system font was changed from Lucida Grande to Helvetica Neue.

Three weights of Lucida Grande: Normal, Bold, and Black, in three styles: Roman, Italic, and Oblique, were developed by Bigelow & Holmes.

In June, 2014, Bigelow & Holmes released four weights: Light, Normal, Bold, and Black, in three styles: Roman, Italic, and Oblique.

Apart from macOS releases prior to OS X Yosemite, many websites and blogs use Lucida Grande as the default typeface for body text, for example Facebook and many phpBB forums.

[6] Although it was designed primarily as a screen font, Lucida Grande/Sans also appears frequently in print, due at least in part to the ubiquity of Mac platform (and thus the typeface) in professional-grade desktop publishing.
