macOS Monterey (version 12) is the 18th 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 is expected to be released later in 2021. A beta version of macOS Monterey was released to developers enrolled in the Apple Developer program on June 7, 2021. A public beta version was released at the beginning of July 2021.
The operating system is named after Monterey Bay, following Apple's tradition of naming macOS releases after locations in California that started with OS X (now macOS) 10.9 Mavericks replacing the former tradition of naming each macOS release after big cats.
Changes
Some of the major features showcased during the WWDC 2021 keynote include:
- Introduction of Shortcuts for the Mac
- Introduction of TestFlight for the Mac
- Universal Control, which allows a single keyboard and mouse to interact across multiple Macs and iPads at once (Available on Mac computers with the Apple M1 chip and Mac computers with an Intel processor and at least 16GB RAM and 4GB VRAM. iPad requirements: iPad Pro, iPad Air (3rd generation and later), iPad (6th generation and later), and iPad mini (5th generation and later).)

Applications
Notes
The Notes application includes the ability to apply arbitrary, user-generated tags to any note (e.g. #cooking, #work). A complementary Tag Browser in the sidebar and Smart Folders allow visualization of notes tagged with a particular tag or combination of tags. New functionality called Quick Notes enables the creation of a note from within any app via invocation of a system-wide keyboard shortcut or hot corner.
Maps
The Maps app includes a new interactive globe, redesigned transit experience, and new place card. The interactive globe lets you discover the natural beauty of Earth with a rich and interactive 3D globe, including significantly enhanced details for mountain ranges, deserts, forests, oceans, and more.
