macOS Sequoia (version 15) is the twenty-first major release of Apple's macOS operating system, the successor to macOS Sonoma. It was announced at WWDC 2024 on June 10, 2024.[1] In line with Apple's practice of naming macOS releases after landmarks in California, it is named after Sequoia National Park, located in the Sierra Nevada mountain range.[2]

The first developer beta was released on June 10, 2024.[3] The first public beta was released on July 15, 2024.[4] It was released on September 16, 2024.[5] Sequoia was the first macOS version released on the same day as a new iOS and iPadOS version.[6]

It was succeeded by macOS Tahoe, which was released on September 15, 2025.[7]

Sequoia is the final version of macOS to officially support the iMac Pro, the 2019 iMac, most Intel-based MacBook Pros (excluding the 2019 16-inch model and the 2020 13-inch with four Thunderbolt 3 ports model), 2018 Mac Mini, and the 2020 Intel MacBook Air as its successor, macOS Tahoe, drops supports for those models. It is also the final version to officially support Macs that do not feature the T2 security chip, and any Intel-based MacBook Airs and Mac Minis.

Development

macOS Sequoia was announced by Senior Vice President of Software Engineering Craig Federighi at Apple's Worldwide Developers Conference (WWDC) on June 10, 2024.[1] It was announced alongside iOS 18, iPadOS 18 and watchOS 11.[8] Eight developer betas and six public betas were released.

Features

macOS Sequoia introduced several new features and improvements, mainly focused on productivity:

  • iPhone Mirroring, a feature to mirror and interact with content from an iPhone running iOS 18 as a macOS window, has been introduced. It is supported on all Macs that run Sequoia except the 2019 iMac, which lacks a T2 chip.[1] This function is not available in the European Union due to the lack of conformity to the Digital Markets Act (DMA).[9]
  • The Calculator app has been redesigned to be more similar to that of iOS and iPadOS, including rounded buttons, departing from the design that has been used since OS X Yosemite.
  • Notes has been updated with the Math Notes feature, which can be used to calculate simple equations, evaluate expressions, and assign variables within the app.
  • Passwords, a cross-platform password manager application, was introduced, which replaces Keychain.[1]
  • In System Settings, individual menus have been rearranged and slightly redesigned to quickly access frequently used menus.
  • Safari has been revamped, including revamped reader mode (now called Reader), faster page load times, a new start page, a new option to hide a singular element on a webpage, and a new unified menu; these had previously been exclusive to compact mode on iOS/iPadOS.
  • macOS Sequoia includes the second iteration of Game Porting Toolkit, a Windows API compatibility layer derived from Wine and CrossOver,[10] allowing developers to more easily port Windows games to macOS.[1]
  • Apple Intelligence is available on all Apple silicon Macs (except those purchased in mainland China) and includes artificial intelligence features such as a redesigned Siri, Writing Tools with which selected text can be proofread or have its tone changed, Smart Reply in Mail to quickly draft email responses, and a system-wide integration with ChatGPT.[11]
  • Window tiling is now automatically suggested by macOS when dragging a window to the edges of the display, similar to the Aero Snap feature included in Microsoft Windows.
  • The Tips app is now an independent app from the rest of the operating system. The user interface (UI) has also been redesigned, and has replaced the previous Help system included in earlier versions of macOS. The app surfaces individual user guides for apps such as Freeform, Pages, Keynote, Notes, and Apple TV, and also surfaces user guides for any other devices a user may own, such as an iPhone, Apple Watch or Apple TV. As an independent app, it can also be pinned to the Dock.

Supported hardware

macOS Sequoia supports Macs with Apple silicon and those with Intel's Skylake-based Xeon W and 8th-generation Coffee Lake chips or later. A Mac with an M1 chip or later is required to use Apple Intelligence. macOS Sequoia supports every Mac that supports macOS Sonoma, with the exception of the 2018 and 2019 MacBook Air models with Intel Amber Lake chips. Similar to Sonoma, the 2019 iMac is the only supported Intel Mac that lacks a T2 security chip. macOS Sequoia is the first version of macOS to drop support for a Mac with a T2 security chip.

macOS Sequoia is the final version of macOS to support any Intel-based Mac Mini and Intel-based MacBook Air models, as its successor, macOS Tahoe, only supports any Apple silicon-based Mac Mini and Apple silicon-based MacBook Air models.

The following devices are compatible with macOS Sequoia:[12]

  • iMac (2019 and later)
  • iMac Pro (2017)
  • MacBook Air (2020 and later)
  • MacBook Pro (2018 and later)
