The operating system is named after Monterey Bay, continuing the trend of releases named after California locations since 2013's 10.9 Mavericks.

macOS Monterey is the final version of macOS that supports the 2015–2017 MacBook Air, Retina MacBook Pro, 2014 Mac Mini and cylindrical Mac Pro, as its successor, macOS Ventura, drops support for those models.

Changes

Monterey introduced several new features and changes, including the following:[3]

  • Shortcuts for the Mac
  • TestFlight for the Mac
  • Provisions to allow the planned introduction of Universal Control,[9] which allows a single keyboard and mouse to control multiple Macs and iPads. It works on Macs with Apple silicon 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).
  • Support for the Apple Music Voice Plan Subscription.
  • Portrait Mode and Noise Cancellation features for FaceTime and some apps (in Control Center).
  • New Toolbar features and designs for Finder and the Preview app.
  • Have a Live Memoji and Animoji right on the lock screen.
  • A yellow privacy indicator on the menu bar for indicating if the Mac's microphone or camera is active.
  • Live Text, which allows a user to copy, paste, translate and look up text from images displayed by Photos, Screenshot, Quick Look, and Safari.
  • New Passwords Manager for Mac
  • New on-device machine-learning–activated keyboard dictation using Siri, and also now for almost unlimited duration.
  • Low Power Mode for Mac that enables longer battery life for lightweight workflows such as reading PDFs, Web browsing, listening to music, etc. This works on MacBook Air (2018 and later) and MacBook Pro (2016 and later).[10]
  • A redesigned optional compact interface for the 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 (M1, 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 Mac from the System Preferences app.[11]
  • Visual Look Up makes it easy to identify objects (e.g. cat breeds, dog breeds, etc.) found within user's photos.
  • Focus to set different modes to filter notifications across iPhones, iPads and Macs.
  • The Time Machine backup functionality excludes more system files.[12]
  • 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.[13]
  • Accessibility option to change the mouse pointer's colors.
  • Tips notifications.
  • The removal of a previously bundled PHP interpreter.[14]
  • The removal of a previously bundled Python 2.7 interpreter (from 12.3)[15][16]
  • 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
  • An automatically populated "Games" folder within launchpad
  • Support for ProMotion in new 2021 MacBook Pro
  • New Object Capture API for creating 3D models using images[17]

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.[18] The new Quick Notes function enables a user to create a note from within any app via system-wide keyboard shortcut or hot corner.[19]

Maps

Apple Maps adds a 3D globe, with increased mountain, desert, and forest detail.[20]

Messages

Messages supports new features, also introduced in iOS 15, such as "Shared with You" which provides shortcut links to content shared via Messages in other Apple apps such as Safari, Photos, Music, and News.

When multiple photos are sent/received, they are now displayed as a collection instead of multiple messages. A download button is provided to download all photos simultaneously.[21]

Known problems

Users and developers have reported the following:

  • Laptops unable to boot (fixed with 12.0.1 update)[22][23]
  • Inability to charge sleeping laptops with MagSafe (fixed with 12.1 update)[24]
  • Mouse pointer memory leak issue (fixed with 12.1 update)[25]
  • Audio issue with speaker and audio output crackling and popping[26]
  • Problems connecting external displays to Mac using any version of Monterey[27]
  • Unicode Hex Input does not work if the code point number is 0xx0 (first and last digits are zero)[28] (fixed in Ventura 13.3)

See Apple's official list on their website

macOS Monterey drops support for various Macs released from 2013 to 2015,[29][30] including all Macs with Nvidia GPUs. When Monterey was released, it supported the following Macs:

By using patch tools, macOS Monterey can be installed on earlier computers that are officially unsupported, such as the 2014 iMac and the 2013 MacBook Pro.[31] Using these methods, it is possible to install macOS Monterey on computers as old as a 2008 MacBook Pro and iMac and 2009 Mac Mini.[32]
