« The biggest change since the launch of Mac OS X “. When he unveiled macOS Big Sur at WWDC, Craig Federighi didn’t go by half measures. And this was not to talk about the migration to Apple Silicon chips – historic decision if there was one – but a prelude to the presentation of the new interface of the system.
Those who have experienced the switch from a flat, drab Mac OS 9 to a bright and playful Mac OS X Aqua may find Federighi’s words vaguely exaggerated. From Catalina to Big Sur, while the change is visible, it is also not deep or dramatic. We can argue that the move from Mavericks to Yosemite in 2013 had been the occasion for a greater visual break, in the wake of iOS 7 a year earlier.
