Apple today previewed macOS Mojave, the latest version of its desktop operating system, with new features inspired by pros.

In macOS Mojave, a new Dark Mode transforms the Mac desktop with a darkened color scheme where content pops and controls recede into the background. Users can toggle between a light and dark desktop, and built-in Mac apps like Mail, Messages, Maps, Calendar and Photos all include Dark Mode designs. macOS Mojave also features a new Dynamic Desktop that automatically changes the desktop picture to match the time of day. An API is available so developers can implement Dark Mode in their apps.

Stacks for the desktop can organize even the most cluttered of desktops by automatically stacking files into neat groups based on file type. Users can customize their Stacks to sort based on other file attributes like date and tags. Finder also gets an update in macOS Mojave with an all-new Gallery View that lets users skim through files visually. The Preview Pane now shows all of a file's metadata, making it easier to manage media assets. Quick Actions allow users to do things like create and password-protect PDFs and run custom Automator Actions on files right from Finder. Quick Look provides a fast, full-size preview of a file, allowing users to rotate and crop images, mark up PDFs and trim video and audio clips without ever opening an app.

In macOS Mojave, apps including News, Stocks, Voice Memos and Home are now available on Mac for the first time. In the News app, users can follow their favorite publications from one app. With Home, Mac users can control their HomeKit-enabled accessories to do things like turn lights off and on or adjust thermostat settings without ever having to step away from their computer. Voice Memos makes it easy to 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, complete with quotes and interactive charts.

Group FaceTime makes it easy to chat with multiple people at the same time. Participants can be added at any time, join later if the conversation is still active and choose to join using video or audio from an iPhone, iPad or Mac - or even participate using FaceTime audio from Apple Watch.

Apple also previewed the completely redesigned Mac App Store, which now features rich editorial content and new tabs for easier app discovery.

The new design highlights new and updated apps in the Discover tab, while tabs for Create, Work, Play and Develop help users find apps for a specific project or purpose. A number of apps from top developers are also coming soon to the Mac App Store, including Office from Microsoft, Lightroom CC from Adobe and more.

Privacy and Security

In Safari, enhanced Intelligent Tracking Prevention helps block social media "Like" or "Share" buttons and comment widgets from tracking users without permission. Safari now also presents simplified system information when users browse the web, preventing them from being tracked based on their system configuration. Safari now also automatically creates, autofills and stores strong passwords when users create new online accounts and flags reused passwords so users can change them. 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.

The developer preview of macOS Mojave is available to Apple Developer Program members at developer.apple.com starting today, and a public beta program will be available to Mac users in late June at beta.apple.com. macOS Mojave will be available this fall as a free software update for Macs introduced in mid-2012 or later, plus 2010 and 2012 Mac Pro models with recommended Metal-capable graphics cards
