Apple releases Safari 15 for macOS Big Sur and Catalina with Tab Groups, new design, and more

Earlier today, Apple released iOS 15, iPadOS 15, watchOS 8, and tvOS 15 to the public. We’re still waiting for the other big update, though. macOS 12 Monterey is still waiting in the wings, which will bring with it plenty of new features to the desktop OS. But today, Apple’s dangling a carrot for all of us waiting for that new software.

Today, Apple released Safari 15.0 to the public — for those running macOS 11 Big Sur and macOS Catalina. With this new software update, Apple is bringing the majority of new features to Safari it introduced alongside macOS Monterey (and iOS 15/iPadOS 15), without having to bring macOS Monterey to the fore quite yet.

As far as what’s new, Safari itself has a new design. This should make it easier to get around, to navigate from one website to another. There are new tabs, too. Including brand new Tab Groups, making them easy to access across devices, and organize tabs more easily.
