Support status

macOS Mojave (/mˈhɑːvi, mə-/ mo-HAH-vee) (version 10.14) is the fifteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. The successor to macOS High Sierra, it was announced at the WWDC 2018, on June 4, 2018,[6][7] and was released to the public on September 24, 2018.[1]

It brings several iOS apps to the desktop, including Apple News, Voice Memos, and Home; includes a much more comprehensive "Dark mode",[8] and is the final version of macOS to support 32-bit apps.[9]

Its name refers to the Mojave Desert, and is the latest California-themed name in a series begun with OS X Mavericks.[10]

System requirements[edit]

macOS Mojave will run on the following Macintosh computers:[11]

macOS Mojave drops support for many older Mac models because it relies on Metal, which requires Intel HD and Iris Graphics 4000 series or newer, AMD GCN-based GPUs, or Nvidia Kepler-based GPUs or newer.

macOS Mojave requires at least 2 GB of RAM. It requires at least 12.5 GB of available disk space to upgrade from OS X El Capitan, macOS Sierra, or macOS High Sierra and at least 18.5 GB of available disk space to upgrade from OS X Yosemite and earlier releases.[12]



Deprecation of OpenGL and OpenCL[edit]

As of macOS Mojave, OpenGL and OpenCL are deprecated. They are still supported by the operating system, but will no longer be maintained; developers are encouraged to use Apple's Metal library instead.[13]

OpenGL is a cross-platform graphics framework designed to support a wide range of processors. Apple chose OpenGL in the late 1990s to build support for software graphics rendering into the Mac, after abandoning QuickDraw 3D. At the time, moving to OpenGL allowed Apple to take advantage of existing libraries that enabled hardware acceleration on a variety of different GPUs. As time went on, Apple has shifted its efforts towards building its own hardware platforms for mobile and desktop use. Metal makes use of the homogenized hardware by abandoning abstraction layer and running on the "bare metal". Metal reduces CPU load, shifting more tasks to the GPU. It reduces driver overhead and improves multithreading, allowing every CPU thread to send commands to the GPU.[14]

macOS does not natively support Vulkan, the official successor to OpenGL. The MoltenVK library can be used as a bridge, translating most of Vulkan 1.0 API into to Metal API.[15][16] In particular, Valve successfully uses MoltenVK for its Dota 2 game.[17]

32-bit app warnings[edit]

In macOS High Sierra (10.13.4), a warning was issued the first time a 32-bit app was opened that 32-bit apps will not be supported in future updates. In macOS Mojave, this alert appears once every 30 days when launching the app, as the next version of the OS will not support them.[9]

macOS updates[edit]

macOS updates are shown in System Preferences instead of the Mac App Store.[18] In OS X Mountain Lion (10.8), system and app updates moved to the App Store from Software Update.

Added features[edit]

Dark Mode and accent colors[edit]

Users can switch to Dark mode to transform their desktop to a darkened color scheme, putting the focus on user content while interface elements and controls recede into the background.[citation needed] Built-in apps like Mail, Messages, Maps, Calendar and Photos include Dark mode designs. App developers can implement Dark mode in their apps via a public API.[19]

A limited dark mode that affected only the dock, menu bar, and drop-down menus was introduced in OS X Yosemite.[20]

Dynamic Desktop[edit]

macOS Mojave features a new Dynamic Desktop that automatically changes the desktop picture to match the time of the day.[21]

Desktop and Finder[edit]

Stacks, a feature introduced in Mac OS X Leopard, has expanded to the Desktop. Users can organize cluttered icons by automatically stacking files into groups based on file attributes such as file kind, date last opened, date modified, date created, name and tags. Finder also gets an update, adding a Gallery View (replacing Cover Flow) that lets users browse through files visually. The Preview Pane now shows all of a file’s metadata.[22]

New apps and iOS app support[edit]

Four new apps (News, Stocks, Voice Memos and Home) are included in macOS Mojave; they are directly ported from iOS, with Apple implementing a subset of UIKit on the desktop OS.[23] Third-party developers will be able to port iOS applications to macOS in 2019.[24]

With Home, Mac users can control their HomeKit-enabled accessories to do things like turn lights off and on or adjust thermostat settings. Voice Memos lets users record personal notes, lectures, meetings, interviews and song ideas, and access them from iPhone, iPad or Mac. Stocks delivers curated market news alongside a personalized watchlist, with quotes and charts.[25]


macOS 10.14.1, released on October 30, 2018, adds Group FaceTime, which lets users chat with up to 32 people at the same time, using video or audio from an iPhone, iPad or Mac, or audio from Apple Watch. Participants can join in mid-conversation.[26]

App Store[edit]

In macOS Mojave, the Mac App Store was rewritten from the ground up and features a new interface and editorial content, similar to the iOS App Store. A new 'Discover' tab highlights new and updated apps; Create, Work, Play and Develop tabs help users find apps for a specific project or purpose.[27]

Privacy and security[edit]


Safari's Tracking Prevention features now prevent social media "Like" or "Share" buttons and comment widgets from tracking users without permission. The browser also sends less information to web servers about the user's system, reducing the chance of being tracked based on system configuration.[28] It can also automatically create, autofill, and store strong passwords when users create new online accounts; it also flags reused passwords so users can change them.[29]


New data protections require apps to get user permission before using the Mac camera and microphone or accessing personal data like user Mail history and Messages database.[30]
