To answer the question directly: Apple uses (SF Pro) as the primary font in all its keynote presentations. However, the deeper answer is that Apple uses no off-the-shelf font . By designing San Francisco, Apple ensured that the reading experience on a 200-foot screen is identical to that on a 1.5-inch watch face. The font is not just a style choice; it is a proprietary tool of control, clarity, and brand consistency. When you see that crisp, ultra-legible sans-serif slide announcing a new product, you are not seeing Helvetica’s legacy—you are seeing Apple’s future, carefully kerned and perfectly spaced.

With the launch of iOS 7 and OS X Yosemite, Apple shifted toward ultra-thin, hyper-minimalist aesthetics. For a brief period, Keynote slides featured thin weights of Helvetica Neue. While beautiful on paper, its tight spacing and uniform geometric shapes proved difficult to read on projector screens, prompting the creation of San Francisco.
