Craig Federighi unveiled the macOS Tahoe 26 at Apple's Worldwide Developers Conference (WWDC) 2025 on Monday. The transformative update to the Mac operating system comes with several features, including the use of a new material called Liquid Glass, which gives apps and system elements like the Dock and menu bar a translucent, reflective look. Even icons have been redesigned with newer tints and themes.

Federighi, Apple’s Senior Vice President of Software Engineering, was at the center stage of the event. Known for his presentations and technical prowess, Federighi has been the driving force behind Apple’s operating systems for over a decade.
