macOS Monterey (version 12) is the eighteenth and current major release of macOS, Apple's desktop operating system for Macintosh computers. The successor to macOS Big Sur, it was announced at WWDC 2021 on June 7, 2021, and released on October 25, 2021. macOS Monterey will be succeeded by macOS Ventura, which was announced at WWDC 2022 on June 6, 2022.
The operating system is named after Monterey Bay, continuing the trend of releases named after California locations since 2013's 10.9 Mavericks.
Monterey introduced several new features and changes, including:
