Other changes include lighter windows with additional translucency, a more translucent dock, app icons with a new uniform squircle shape, redone system sounds, and more. While subtle, the changes should have a fresh feel in comparison to the current macOS. This includes overhauling the curvature of window corners and dock icon designs.
MacOS Big Sur was previously revealed at WWDC in June, and will feature an overhauled look with what Apple is calling the biggest design update to macOS since the introduction of Mac OS X. The news came out of Apple's 'One More Thing' event, where it revealed new Mac mini, MacBook Air, and MacBook Pro models with the M1 chip.
Apple today announced that macOS Big Sur will be released on Thursday, November 12.
