After Apple finally decided to reverse its controversial Safari design changes in the latest macOS Monterey beta (when you use the “Separate” tabs option), it has made the same move for those running macOS Big Sur and Catalina.
The Safari 15.1 update released Wednesday for earlier versions of macOS brings back Safari’s old tab design. However, if you prefer the new “Compact” interface — introduced at WWDC 2021 back in June — you still have the option to use it.
