The day has finally arrived. The latest version of macOS is here, after a seemingly endless wait. That wasn’t just your imagination, either. Sure time is basically meaningless now, but this one did take a while to arrive, with nearly five months between its announcement at WWDC and today’s public release.
There are, no doubt, plenty of reasons for this. Among other things, this has been an usual year, to put it as benignly as possible. This also marks a pretty big annual update for the desktop operating system. And then, of course, there’s the fact that this is the first version of macOS expressly built for the company’s new Arm-based Macs — the single largest change to Apple hardware in roughly 14 years.
I’ve been running a beta of the operating system on one of my machines since June, along with developers and a smattering of brave souls. I’m not saying we’re heroes — but I’m also not not saying that. At the end of the day, it’s not for me to say.
The update brings a slew of design updates — many of which continue the longstanding trend of blurring the line between macOS and iOS. It’s a trend that may well intensify as Apple silicon ushers in the next era of Macs. At the very least, it makes sense from the standpoint of iOS having long ago taken the pole position in Apple’s software design. The mobile operating system has been the first to introduce many features that have eventually found their way onto the desktop.

Many of the changes are subtle. The menu bar is taller and more translucent, changing with different backgrounds and as the system toggles between light and dark mode. The Finder dock now floats a touch above the bottom of the screen and menus have a little more space to breathe. Windows offer a bit more space, as well, along with a smattering of new symbols scattered throughout first-party apps like Mail and Calendar.

The shapes of the icons have changed to a more iOS-like squircle design, with subtle touches throughout — the Mail icon, for instant, sports the address of Apple’s HQ in barely visible text: “Apple Park, California 95014.” Like many of the other touches, the key is offering up a kind of stylistic consistency, both throughout Big Sur and across the Apple ecosystem.

The most immediate and obvious change to the finder, however, is the addition of the Control Center. The feature is borrowed directly from iOS/iPadOS, bringing a simple, clean and translucent pane down to the right side of the screen. You can drag and drop the panels directly into the menu bar. It brings to mind the sort of control center functionality the company introduced with the Touch Bar, but more than anything the big buttons and sliders beckon you to reach out and touch the screen. It’s really hard to shake the feeling that the company is starting to lay the groundwork for future touchscreen Macs running Apple silicon.

I won’t lie: I’ve never been a big Notification Center user. I understand why Apple thought to bring the center to the desktop several updates ago, but it’s just not as centralized as it is on mobile. Nor does it fit into my existing workflow. Apple has continued tweaking the feature — and it gets a pretty sizable overhaul here. Like much of the rest of the updates, it’s about how Apple uses space.
Now accessible by clicking the date and time in the menu bar (versus a devoted button), the two most appealing changes here are grouped notifications and widgets. Again borrowing from iOS, notifications are now stacked by group. Tapping the top of the pile will expand them down. You can “X” them out on the side to make them go away — but again, a swipe would be more satisfying. Also notable is the ability to interact with notifications. You can reply to messages or listen to podcasts straight from the river. It’s a nice addition for those who already use the feature as part of their workflow.

The system also joins the latest version of iOS with the addition of new widgets into the Notification column. Currently the list includes first-party apps like Calendar, Weather and Podcasts, along with additional widgets available via the App Store. You can add and remove widgets and resize them. On a screen with enough real estate, it might be nice to pin them to the top, so they can stay open and anchored in place, while you’re working in other applications.
