Changes

Monterey introduced several new features and changes, including:[4]

  • Shortcuts for the Mac
  • TestFlight for the Mac
  • Provisions to allow the planned introduction of Universal Control,[10] which allows a single keyboard and mouse to control multiple Macs and iPads. It works on Mac computers with the Apple M1 chip and some with an Intel processor, including MacBook Pro (2016 and later), MacBook (2016 and later), MacBook Air (2018 and later), iMac (2017 and later), iMac (5K Retina 27-inch, Late 2015), iMac Pro, Mac mini (2018 and later), and Mac Pro (2019). It works on these iPads: iPad Pro, iPad Air (3rd generation and later), iPad (6th generation and later), and iPad mini (5th generation and later).
  • Live Text, which allows a user to copy, paste, translate and lookup text from images displayed by Photos, Screenshot, Quick Look, and Safari.
  • Low Power Mode for Mac. This works on MacBook (Early 2016 and later) and MacBook Pro (Early 2016 and later).[11]
  • A redesigned Safari browser.
  • Support for playing AirPlay content streamed from recent iOS and iPadOS devices and Macs, including: MacBook Pro (2018 and later), MacBook Air (2018 and later), iMac (2019 and later), iMac Pro (2017), Mac mini (2020 and later), Mac Pro (2019), iPhone 6s and later, iPad Pro (2nd generation and later), iPad Air (3rd generation and later), iPad (6th generation and later), and iPad mini (5th generation and later). Older iPhone, iPad, and Mac models may share content at a lower resolution to supported Mac models when “Allow AirPlay for” is set to “Everyone” or “Anyone on the same network” in Sharing preferences.
  • Improvements to FaceTime, including the ability to share a screen and the SharePlay function that enables multiple users to watch or listen simultaneously and in sync (e.g., to music or TV shows).
  • The ability to factory-reset the device from the System Preferences app[12]
  • Focus to set different modes to filter notifications across iPhone, iPad, and Macs.
  • The Time Machine backup functionality excludes more system files.[13]
  • Provisions to allow the planned introduction of "Expanded Protections for Children" which will apply cryptography to detect and help limit the spread of child sexual abuse material (CSAM) online by scanning the user's iCloud photos and Messages attachments.[14]
  • Accessibility option to change the mouse pointer's colors.
  • Tips notifications.
  • The removal of a previously bundled PHP interpreter.[15]
  • The removal of the ability to use custom Quartz Composer filters and plugins in Photo Booth.
  • networkQuality, a command-line tool for measuring upload/download capacity, upload/download flows, and upload/download responsiveness

Notes

In the Notes application, users can now apply arbitrary tags to a note (e.g., #cooking, #work); groups of notes with a given tag or tags can be viewed in Smart Folders or a Tag Browser in the sidebar.[16] The new Quick Notes function enables a user to create a note from within any app via system-wide keyboard shortcut or hot corner.[17]

Maps

Apple Maps adds a 3D globe, with increased mountain, desert, and forest detail.[18]

macOS Monterey drops support for various Macs released from 2013 to 2015[19][20] including all Macs with Nvidia GPUs. Monterey works on all Macs equipped with Apple silicon SoCs, as well as the following models equipped with Intel CPUs:
