macOS.
It’s why there’s nothing else like a Mac.

macOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone and other Apple devices. And it’s been built from the ground up with privacy and security in mind.

macOS Catalina is here.

See what’s new.

Featuring all-new, dedicated apps for music, TV and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display.

Continuity All your devices.
One seamless experience.

Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. And when friends text you — regardless of the phone they have — you can respond from your Mac, iPad or iPhone, whichever is closest. When you copy text or an image from one device, you can paste it into another with standard copy and paste commands. And with Sidecar, you can extend your workspace by using your iPad as a second Mac display. You can even unlock your Mac with your Apple Watch. No password typing required.

Privacy and Security We believe your data belongs to you. Period.

Everything you do with your Mac is protected by strong privacy and security features. That’s because we build data security into everything we make, from the start.

Privacy. You trust our products with your most personal information and we believe that you should be in complete control of it. We respect your privacy by enacting strict policies that govern how all data is handled. And when you browse the web, Safari helps prevent data companies from tracking the sites you visit.

Security. We design Mac hardware and software with advanced technologies that work together to help you run apps safely, protect your data and keep you safe on the web. The new Find My app helps you locate a missing Mac that’s lost or stolen — even if it’s offline or sleeping. And Gatekeeper makes it safer to download and instal apps from the Mac App Store and the Internet.

Built in Apps Apps as powerful and elegant as your Mac. Because they’re designed for it.

With every Mac, you get a collection of powerful apps. They’re the same apps you use on your iPhone or iPad, so they’ll feel instantly familiar. They all work with iCloud, so your schedule, contacts and notes are always up to date everywhere. And because they’re native apps — not web apps in a browser — they take full advantage of the power of your Mac to deliver the fastest possible performance and more robust features.

Media. Experience music, TV and podcasts in three all-new Mac apps. Track the market and customise your watchlist. Peruse the best book titles from your desktop. And find the latest apps and extensions for your Mac, directly on your Mac.

Creativity. Enjoy your best photos and videos, showcased in an immersive, dynamic new look. Transform home videos into unforgettable movies or quickly share clips with your favourite people. Create music like the pros with a huge collection of sounds, instruments, amps and a line-up of virtual session drummers and percussionists perfectly suited to play along with your song.

Productivity. Create beautiful documents with stunning simplicity. Visualise your data precisely and persuasively in spreadsheets with images, text and shapes. Make stage-worthy presentations using powerful graphics tools and dazzling cinematic effects to bring your ideas to life. And collaborate with friends and co-workers in real time — whether they’re across town or across the globe.

Communication. Easily manage all of your email accounts in one simple, powerful app that works with email services like iCloud, Gmail, Yahoo, AOL and Microsoft Exchange. Send unlimited messages to anyone on any Apple device, using the same Messages app on your Mac as you do on your iPhone. Make unlimited high-quality video and audio calls directly from your Mac with FaceTime. And securely locate a missing Mac using the new Find My app on Mac, iPhone and iPad.

Organisation. A new gallery view and more powerful search help you find your notes more quickly than ever. Easily create, organise and add attachments to reminders. Manage your iCloud, Google and Exchange calendars in one place, create separate calendars for home, work and school, and view them all or just the ones you want. Instantly capture personal reminders, class lectures, even interviews or song ideas with Voice Memos. Keep all your contact info up to date on all your devices and easily import numbers, addresses and photos from Google and Microsoft Exchange. And control all your HomeKit-enabled accessories from the comfort of your desktop.

Internet. Surf the web seamlessly with an updated start page that helps you quickly access your favourite and frequently visited sites. Map out new destinations from your desktop, with gorgeous 3D city views like Flyover and point-to-point directions. And instantly search your entire Mac or get results from the Internet in just a few keystrokes.

iCloud All your stuff on your Mac.
And everywhere else you want it.

Every Apple app uses iCloud — it’s the magic behind the seamless experience you have with all your Apple devices. So you always have your photos, videos, documents, email, notes, contacts, calendars and more on whatever device you’re using. And any file you store in iCloud Drive can be shared with friends, family and colleagues just by sending them a link. iCloud Drive also lets you access files from your Mac on your iPhone or iPad. It’s all done automatically. Just like that.4

Accessibility We make sure that everyone is able to use a Mac.

macOS comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, providing many features you won’t find in other operating systems. Voice Control lets users control their Mac, iPad and iPhone entirely with their voice. And features such as VoiceOver, Accessibility Keyboard, FaceTime5 and Text to Speech help everyone get more out of Mac.

Technology Advanced to the core.

macOS features powerful core technologies engineered for the most important functions of your Mac. Thanks to Mac Catalyst, you can now enjoy your favourite iPad apps on your Mac. With SwiftUI, developers have a simple way to build better apps across all Apple platforms with less code. Create ML gives developers a faster and easier way to build machine learning into apps. And support for virtual and augmented reality lets developers create immersive worlds for you to step into.

Compatibility Need to work with Windows?
Mac does that too.

With macOS, it’s easy to transfer your files, photos and other data from a Windows PC to your Mac. Work with popular file types such as JPEG, MP3 and PDF, as well as Microsoft Word, Excel and PowerPoint documents. And, of course, you can run Microsoft Office natively on a Mac. If you want, you can even run Windows on your Mac.6
