Dark Mode
Put your best work forward.
Dark Mode is a dramatic new look that helps you focus on your work. The subtle colors and fine points of your content take center screen as toolbars and menus recede into the background. Switch it on in the General pane in System Preferences to create a beautiful, distraction-free working environment that’s easy on the eyes — in every way. Dark Mode works with built-in apps that come with your Mac, and third-party apps can adopt it, too.
Choose what works best for you — the familiar light appearance or the new Dark Mode.
Dynamic Desktop
A desktop whose time has come.
Introducing two new time-shifting desktops that match the hour of the day wherever you are.

Stacks
A really neat way to manage files.
Stacks keeps your desktop free of clutter by automatically organizing your files into related groups. Arrange by kind to see images, documents, spreadsheets, PDFs, and more sort themselves. You can also group your work by date. And if you tag files with project-specific metadata, like client names, sorting by stacks becomes a powerful way to manage multiple jobs. To scrub through a stack, use two fingers on a trackpad or one finger on a Multi-Touch mouse. To access a file, click to expand the stack, then open what you need.
Finder
New ways to view.
More ways to do.
With macOS Mojave, the Finder becomes even more of a doer. Now you can quickly locate a file by how it looks. Instantly see all of a file’s metadata. And perform Quick Actions on files without ever opening an app.
Gallery View
With Gallery View, you can scroll through big previews of your files to visually identify the one you’re looking for. So finding that image of the smiling girl by the Ferris wheel or the PDF with a colorful pie chart has never been faster.
Quick Actions
With Quick Actions in the Preview pane, you can work on files right from the Finder. Rotate images, create PDFs, trim video, and more — without having to open an app or rename and save your file. You can even apply them to multiple files at once, or create a custom Quick Action based on an Automator workflow.
Quick Look
Work on a file without even opening it.
Now a tap of your space bar provides more than just a quick look at a file. It gives you the power to perform actions specific to the kind of file you’re viewing — without ever launching an app. So you can mark up a PDF, rotate and crop an image, even trim audio and video. And when you’re ready, you can share right from Quick Look, too.
Automatic Strong Passwords
macOS Mojave works harder than ever to ensure that your passwords are robust and unique. Safari automatically creates, stores, and autofills strong passwords for you. And it flags existing passwords that have been reused in Safari preferences, so you can easily update them. Security has never been so user friendly.
Enhanced Tracking Prevention
When you browse the web, the characteristics of your device can be used by advertisers to create a “fingerprint” to track you. Safari now thwarts this by only sharing a simplified system profile. And now improved Intelligent Tracking Prevention keeps embedded content such as social media Like buttons, Share buttons, and comment widgets from tracking you without your permission. We know you’ll like that.
View website icons in Safari tabs
Identify all your open sites with just a glance by enabling website icons in Safari preferences.
Easily add emoji in Mail
Compose more expressive email with a click of the new Emoji button. And when you select a message in your inbox, Mail can suggest the right mailbox to file it in.
Ask even more of Siri
Siri now controls HomeKit-enabled devices. It can help you find saved passwords. And Siri knows much more about food, celebrities, and motorsports.
Mac is more fluent than ever
macOS Mojave adds UK English, Australian English, Canadian French, and Traditional Chinese for Hong Kong language options; improved maps for China mainland; and romanized English input for Japanese keyboard.
Upgrade to macOS Mojave
macOS Catalina
The power of Mac.
Taken further.
Apple's MacOS High Sierra update offers lots of behind-the-scenes changes that should make the Apple's desktop OS easy to use. High Sierra might disappoint those looking for whizzy new features, but Apple's focus on core improvements will make for a more responsive and more secure OS.
Pros
Flashy file system: With High Sierra, Apple switches to a new file system for MacOS flash storage. Called Apple File System, MacOS's new file system is now used across all Apple platforms -- from the Apple Watch and Apple TV to the iPhone and Macs -- to organize storage. Apple File System is tailored for flash storage and solid state drives and replaces HFS+, the hard-disk-drive file system Apple rolled out in 1998. The Mac's new file system will also focus on privacy and security, Apple said, and embrace full disk encryption. And because the new file system is designed for SSDs, the system and apps should feel more responsive.
Be aware that just Macs with SSD drives will get the new file system. If you have a Mac with a hard-disk drive or hybrid Fusion drive, you will stay on HFS+.
And a note of caution: Because High Sierra incorporates a new file system, make sure you've got a complete and current backup of the contents of your storage device before upgrading to High Sierra in case the upgrade goes south. And unless you absolutely have to run High Sierra, consider holding off on moving to the new OS until Apple and early adopters have had a good chance to test it out.
Photos gets more organized, with more powerful editing tools: Photos for MacOS High Sierra has an improved sidebar designed to let you more easily organize and access photos, including letting you reorder sections by dragging them around. Apple also tweaked the toolbar so you can easily navigate to photos, Moments, Collections, and Years. And Photos gains a powerful collection of editing tools, including new filters, a new curves tool for tuning color and contrast, and a selective color tool for making changes to a specific color in an image. And you can add effects to Live Photos. And if you have a favorite non-Photos editor, High Sierra lets you edit images in Photos in a third-party app; Photos saves your edits in a layer.
Snappier browsing: Apple said it's made improvements under Safari's hood that will result in the fastest browser experience. Safari will also give you better control over website tracking on autoplay videos.
Better video: Apple is incorporating H.265 into High Sierra. That's High Efficiency Video Coding, a new video compression standard that should produce better-looking video and take up less space. More broadly, Apple is reworking how the OS handles graphics for high-performance games and VR.
Nice changes throughout: High Sierra includes a basketful of updates to the standard collection of Mac apps: You can now check flight status in Spotlight; Siri gets a more natural sounding voice; you add tables to Notes; iCloud gains improved file sharing; you can capture Live Photos in FaceTime; and you have finer control over Family Sharing.
Still free: It's easy to overlook now, but Apple used to charge for its OS. The first wobbly public beta of Mac OS X, for example, cost $29.95 17 years ago. Apple can give away its OS by making money on its hardware and services and taking a cut of third-party app sales.
Same system requirements as Sierra: You should be able to run High Sierra on the same Macs as its predecessor ran on: iMacs and MacBooks from late 2009 and later; and MacBook Airs, the MacBook Pros, Mac Minis, and Mac Pros from 2010 and later.
Cons
iTunes frustration: From selling movies to managing your music, iTunes tries to do it all. But having one app manage your songs, TV shows, movies, and podcasts can make you crazy. (At least Apple removed iOS app purchases.) iOS takes a more sensible approach, splitting iTunes into individual apps for music, video, and store purchases, so you know where exactly to look for your items.
Limited iCloud backup: To make a local backup, Mac users have the handy Time Machine utility. But simple backup to the cloud -- like what iOS offers through iCloud Backup -- is lacking. While Mac users can use third-party tools for remote backup, a built-in method from Apple that uses iCloud would be welcome.
Bottom Line
Apple continues to perfect its desktop OS with High Sierra. Many of the improvements are under the hood, so the new OS may not look much different, but users will get a more stable, more secure, and more responsive MacOS.
