GUI: macOS 11 Big Sur

Big Sur was released in 2020, alongside the first Macs running Apple's own in house processors instead of Intel. In addition to being the first version compiled for both x86 and ARM architectures, Big Sur is the first version of the Mac operating system in 20 years to break the "10.X.X" version numbering scheme. Though early beta versions identified as macOS 10.16, the final release was officially numbered macOS 11. The GUI saw the most significant change since Yosemite as Apple continues to integrate iOS features and visual stylings.

You may notice that screenshots in this post have a bit of an orange tint to the windows. Big Sur introduced a feature (seen in this particular preference pane) that tints windows based on the color of the wallpaper. Since this feature is on by default, the screenshots here show a tint that matches the default wallpaper.

Catalina was released in 2019 and was the first version of macOS to drop support for 32 bit Intel apps. Going forward, only 64 bit apps would run under macOS.

A notable change in Catalina was the discontinuation of the venerable iTunes app. The functionality is now split between three apps. Music, Podcasts, and TV. Device synchronization is now a function of the Finder. Apple still distributes iTunes for Windows as an all in one app with all the aforementioned functions.
