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 WWDC 2018 on June 4, 2018, and was released to the public on September 24, 2018.[4][5][1]

macOS Mojave brings several iOS apps to the desktop operating system, including Apple News, Voice Memos, and Home. It also includes a much more comprehensive "dark mode", and is the final version of macOS to support 32-bit application software.[6][7]

The operating system's name refers to the Mojave Desert and is part of a series of California-themed names that began with OS X Mavericks.[8]

System requirements[edit]

macOS Mojave runs on the following Macintosh computers:[9]

macOS Mojave requires at least 2 GB of RAM and 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.[11]


System updates[edit]

macOS Mojave deprecates support for a number of legacy features of the OS. The graphics frameworks OpenGL and OpenCL are still supported by the operating system, but will no longer be maintained; developers are encouraged to use Apple's Metal library instead.[12]

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.[13]

macOS does not natively support Vulkan, the industry's official successor to OpenGL. The MoltenVK library can be used as a bridge, translating most of the Vulkan 1.0 API into to the Metal API.[14][15] In particular, Valve successfully uses MoltenVK for its Dota 2 game.[16]

Continuing the process started in macOS High Sierra (10.13), which issued warnings about compatibility with 32-bit applications, Mojave issues warnings when opening 32-bit apps that they will not be supported in future updates. In macOS Mojave 10.14, this alert appears once every 30 days when launching the app, as macOS 10.15 will not support 32-bit applications.[7]

When Mojave is installed, it will convert solid-state drives (SSDs), hard disk drives (HDDs), and Fusion Drives, from HFS Plus to APFS. On Fusion Drives using APFS, files will be moved to the SSD based on the file's frequency of use and its SSD performance profile. APFS will also store all metadata for a Fusion Drive's file system on the SSD.[17]

New data protections require applications to get permission from the user before using the Mac camera and microphone or accessing system data like user Mail history and Messages database.[18]


Mojave features changes to existing applications as well as new ones. Finder now has metadata preview accessed via View > Show Preview, and many other updates,[19] including a Gallery View (replacing Cover Flow) that lets users browse through files visually.[20] After a screenshot is taken, as with iOS, the image appears in the corner of the display. The screenshot software can now record video, choose where to save files, and be opened via shift + cmd 5.[21]

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.[22] 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.[23]

A new Screenshot app was added to macOS Mojave to replace the Grab app. Screenshot can capture a selected area, window or the entire screen as well as screen record a selected area or the entire display. Screenshot is located in /Applications/Utilities/, same as the Grab app. Screenshot can also be accessed by pressing ⇧ Shift+⌘ Command+5.


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.[24]

App Store[edit]

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.[25]

iOS apps ported to macOS[edit]

Four new apps (News, Stocks, Voice Memos and Home) are ported to macOS Mojave from iOS, with Apple implementing a subset of UIKit on the desktop OS.[26] Third-party developers will be able to port iOS applications to macOS in 2019.[27]

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 audio (e.g., personal notes, lectures, meetings, interviews, or song ideas), and access them from iPhone, iPad or Mac. Stocks delivers curated market news alongside a personalized watchlist, with quotes and charts.[28]

User interface[edit]

Dark mode and accent colors[edit]

Dark mode changes the desktop to a darkened color scheme, putting the focus on user content while interface elements and controls recede into the background.[29] 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.[30]

A limited dark mode that affected only the Dock, menu bar, and drop-down menus was previously introduced in OS X Yosemite.[6]


Stacks, a feature introduced in Mac OS X Leopard, now lets users group desktop files into groups based on file attributes such as file kind, date last opened, date modified, date created, name and tags.[20][21] This is accessed via View > Use Stacks.[19]

macOS Mojave features a new Dynamic Desktop that automatically changes specially made desktop backgrounds (two of which are included)[31] to match the time of day.[32]


The Dock has a space for recently used apps that have not previously been added to the Dock.[19]


macOS update functionality has been moved back to System Preferences from the Mac App Store.[19][33] In OS X Mountain Lion (10.8), system and app updates moved to the App Store from Software Update.


On September 24, 2018, Andrew Cunningham wrote for Ars Technica that productivity improvements are "probably the biggest since El Capitan reworked the operating system's window management" and that Mojave "continues High Sierra's foundational work on the operating system.[34]

TechCrunch’s Brian Heater dubbed Mojave "arguably the most focused macOS release in recent memory", playing an important role in reassuring professional users that it was still committed to them.[35]
