The previous version of macOS introduced in 2021. Running only 64-bit applications, which started with macOS Catalina, a highly touted feature in Monterey is Universal Control, which enables a single keyboard to operate a Mac and iPad side-by-side. Enabled by Wi-Fi Direct, the mouse and cursor move from one screen to the other, and users can drag and drop between the two. Three devices can also work together.
There are cosmetic changes to Safari, and Maps has a 360-degree street view for various cities. The spatial audio feature in Facetime makes the speaker's voice appear to come from that location on screen. SharePlay displays content from another device, and Focus lets users fine tune their canned responses. A Passwords tab in System Preferences displays a list of all passwords, and the Mail app has enhanced privacy. When getting rid of the machine, an Erase All Content feature works instantly.
