Apple Keyboard (A1242), introduced with the iMac revision in 2009.
“Apple’s keyboards were long labeled with Univers 57 (Condensed Oblique), a design choice by Apple’s industrial design partner, Frog Design. This began in 1984 with the Apple IIc, which had tilted front-panel buttons to match the inclination of the lettering. Univers was eventually replaced on Apple’s keyboards by VAG Rounded, which has been used on all iBook models, PowerBooks introduced after 2003, MacBooks, MacBooks Pro, MacBooks Air, and Apple Keyboards since August 2007.” — Wikipedia
In March 2015, Apple marked its first departure from VAG Rounded as a standard for its keyboards by using its own San Francisco typeface on their new MacBook models.
