OS X. It’s what makes a Mac a Mac.

OS X is the operating system that powers every Mac. Built on a rock-solid UNIX foundation, it’s engineered to take full advantage of what the hardware is capable of. And it’s designed to deliver the most intuitive and integrated computer experience in the world.

Software and hardware made for each other.

OS X is built to bring out the best in your Mac, so you get a fully integrated system in which everything works together seamlessly. It works with the processor in your Mac to deliver the best possible performance. It works with the super-responsive trackpad in Mac notebooks so Multi‑Touch gestures feel natural to use. Technologies like Power Nap take advantage of the Mac hardware to keep the entire system up to date while it sleeps.1 OS X gives you long battery life with advanced power-saving technologies like Timer Coalescing and App Nap. And it’s optimised for the high-resolution Retina display in the high-performance MacBook Pro.

Easy to learn. Easy to use. Easy to love.

From the desktop you see when you start up your Mac to the applications you use every day, everything is designed to be easy and intuitive. On a Mac, it’s easy to find, share and do just about everything. You can control your Mac with simple, intuitive gestures. The Dock makes it easy to open your favourite apps. Launchpad gives you quick access to your full library of apps. The Finder lets you browse and organise your files with ease. Spotlight search makes locating the file you’re looking for effortless. You can even have your apps and the operating system software update automatically. In fact, a Mac does so many things automatically, sometimes you don’t have to do anything at all.

Multi‑Touch, Mac style.

We believe the best way to bring Multi‑Touch gestures to a computer is on the horizontal surface of a trackpad. So navigating your Mac using your fingers to tap, scroll, pinch and swipe feels perfectly natural. And because Apple makes both the hardware and software, Multi‑Touch gestures are remarkably precise. When you scroll down, your document scrolls down. When you scroll up, your web page scrolls up. When you swipe left, your photos move left. These and other gestures make all you do on your Mac easy, intuitive and fun.

Built for power. From the ground up.

Making powerful things simple requires some seriously advanced technologies. OS X is loaded with them. It’s built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability and industry-leading support for Internet standards. OS X takes full advantage of the multicore Intel processors in every new Mac. And the incredible graphics capabilities in OS X allow applications like Aperture and Final Cut Pro to give you unprecedented photo and video editing power.

Advanced features for power users. And everybody else too.

As a desktop operating system, OS X offers powerful ways to get work done as efficiently as possible. For example, you have multiple ways to organise and find files — whether they’re on your Mac, on a server or in iCloud. With Finder Tabs, you can consolidate multiple Finder windows into one, so you can access and organise all your files from a single window. And tags let you organise files so you can easily find them later by searching or simply clicking a tag in the Finder sidebar. If you like to work with multiple applications at the same time, Mission Control gives you a bird’s-eye view of everything that’s running on your system. And if you want to use a second display with your Mac, just plug it in — no configuration required. If you have an Apple TV, you don’t even have to plug in because you can use your HDTV as a fully functional second display over your wireless network.

If you love your iPhone or iPad, you’ll love your Mac too.

If you already use an iPhone or iPad, a Mac will feel instantly familiar. That’s because OS X and iOS have many of the same apps and features — Safari, Mail, Contacts, Calendar, Maps and more. And thanks to iCloud, the apps on your Mac work together with the apps on your iOS devices.2 Whatever you do in apps like Mail, Contacts and Calendar on your Mac happens on your other devices too. So, for example, a contact or a calendar event you add on your iPhone also appears on your Mac. You can send driving directions from your Mac to your iPhone. Add a meeting to your calendar on your Mac and receive an alert on your iPad. Even start an iMessage conversation on your iPhone and finish it on your Mac.

Amazing apps for everyday things.

With OS X, you get a collection of great apps for the things you do every day: surf the web, make FaceTime video calls, send messages, get driving directions, manage your contacts, send email and more. Because they’re built by Apple just for OS X, they’re fully integrated into the operating system and with each other. So with just a few clicks, you can do things like view a map of an address by clicking a contact card, set up a calendar appointment from an email, or share a web page without switching apps. Because they’re native apps — not web apps in a browser — they also take full advantage of the power of your Mac to deliver the fastest possible performance. In addition, whenever there’s an update, you’ll get it automatically. And with the Mac App Store built in, it’s easy to find more great apps.

Designed for mobility. Engineered for better battery life.

OS X is powerful. But it’s also engineered to save power. Advanced technologies like App Nap and Timer Coalescing are built into the operating system and work hand in hand with your Mac to conserve battery life whenever possible — even between keystrokes. It all happens in the background, so you save energy without even knowing it. The result is that you can work and play longer between battery charges — up to an incredible 12 hours with the 13-inch MacBook Air and up to 9 hours with the 11-inch model.3 OS X also includes features that make it easier to take your Mac on the road. For example, it automatically connects to known Wi‑Fi networks. It makes transferring files between Mac computers easy, thanks to AirDrop, which lets you wirelessly move files to nearby computers even if you don’t have an Internet connection. And when you put your Mac to sleep, it wakes up instantly. So it’s ready whenever — and wherever — you need it.

Security was our first thought. Not an afterthought.

Every Mac is designed with advanced technologies that work together to constantly scrutinise, encrypt, update — and ultimately keep your Mac safer. For starters, OS X includes a host of features designed to protect your Mac and the information on it. Gatekeeper makes it safer to download and install apps. FileVault safeguards data using powerful encryption. Sandboxing protects your system by isolating apps from each other, as well as from your system and your data. Find My Mac helps you locate your missing Mac on a map, set a passcode remotely and more. Customisable privacy settings keep your personal information under your control. The best way to keep your Mac up to date with the latest security features? Just install software updates — the Mac App Store notifies you when you have an update. And with OS X Mavericks available free, it’s easier than ever to keep your Mac safe.

Compatible with Windows.

The versatility and power of OS X help a Mac fit in just about anywhere — including Windows networks. Want to transfer your files, photos and other data from a Windows PC? OS X lets you do that easily with Migration Assistant. If you want to run Windows on your Mac, you can do that with Boot Camp.4 OS X has built-in support for the latest version of Microsoft Exchange Server, so you can use your Mac at home and at work and keep all your messages, meetings and contacts in sync. And, of course, you can work with popular file types such as JPG, MP3 and PDF, as well as Microsoft Word, Excel and PowerPoint documents.

Accessibility built in.

OS X comes as standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, including many features you won’t find in other operating systems — at any price. For example, the built-in VoiceOver screen reader, available in over 30 languages, makes it possible for those who are blind or have low vision to control their computers using key commands or gestures on a Multi‑Touch trackpad. Switch Control makes it easier to navigate menus and operate basic controls such as volume, brightness, eject and media playback. OS X also offers out-of-the-box support for more than 40 braille displays (including Bluetooth displays) and many other accessibility features, such as dynamic full-screen magnification, playback of closed captions and a scalable screen.
