While macOS Monterey was not released together with iOS 15 and other OSes, Apple has publishes Safari update for macOS Big Sur and Catalina. Safari 15 brings new features coming in macOS Monterey later this year – redesigned tab bar and tab groups.

Safari 15 delivers faster performance, improved security, and the following new features: 

– Tab Groups help you save and organize your tabs and easily access them across devices 

– Redesigned tabs have a rounder and more defined appearance and take on the color of the webpage 

– Compact tab bar option shows more of your web page on screen 

– HTTPS upgrade automatically switches sites from HTTP to more secure HTTPS when available
