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. So your Mac works like magic with your iPhone and other Apple devices. And it works hand in hand with iCloud to keep photos, documents, and other stuff up to date on those devices. macOS also comes with an entire suite of beautifully designed apps. And it’s been built from the ground up with privacy and security in mind.

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. Need to move a file from one Mac to another? Or copy images, video, or text from your iPhone to your nearby Mac — or vice versa? It’s as simple as copy and paste. With Instant Hotspot, your Mac can remotely activate the Personal Hotspot on your iPhone when they’re near each other.4 They can also automatically pass whatever you’re doing from one device to another — so you can start writing a document on your Mac and finish it on your iPad while you ride to your meeting.5 Look for Apple Pay on your favorite shopping sites, then complete your purchase with Touch ID on your iPhone or MacBook Pro with Touch Bar, or by double‑clicking the side button on your Apple Watch. You can even unlock your Mac just by walking up to it wearing your Apple Watch. No password typing required.*

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.

Make stage-worthy presentations using powerful graphics tools and dazzling cinematic effects to bring your ideas to life. And collaborate with friends and coworkers 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.

iCloud All your stuff. On your Mac, and everywhere else you want it. Automatically.

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 desktop and Documents folder on any iOS device. It’s all done automatically. Just like that.7
