The best browser for your Mac is the one that comes with your Mac. Safari is faster and more energy efficient than other browsers, so sites are more responsive and your notebook battery lasts longer between charges. Built-in privacy features are stronger than ever. It works with iCloud to let you browse seamlessly across all your devices. And it gives you great ways to find and share your favorites. Put it all together, and no other browser offers such a rich web experience.

What's New:

The Safari 10 update is recommended for all OS X El Capitan users and contains improvements to privacy, compatibility, and security. This update:

  • Adds support for Safari Extensions from the Mac App Store
  • Displays HTML 5 video whenever available for faster downloads, better battery life, and stronger security
  • Enhances security by running plug-ins only on websites you authorize
  • Improves AutoFill and adds support for auto-filling information from any contact in Contacts
  • Enhances the formatting in Reader view
  • Remembers Zoom level for each website users visit

Longer battery life and faster performance.

With a blazing-fast JavaScript engine and energy-saving technologies, Safari is a faster, more enjoyable way to explore the web.

Browse longer. Watch more.

Safari is engineered specifically for Mac, so it takes advantage of the powerful technologies built into every one. And Safari now offers native support for Netflix. So compared with Chrome and Firefox, you can browse for up to two hours longer and watch Netflix videos up to three hours longer.

Faster than Chrome and Firefox.

Browsing with Safari is blazing fast thanks to advanced JavaScript engine optimizations that make websites and web applications feel snappier.

Defending your online privacy and security.

Privacy and security aren’t just something you should hope for — they’re something you should expect. That’s why features to help protect your privacy and keep your Mac secure are built into Safari. For example, it’s the only browser to offer DuckDuckGo — a search engine that doesn’t track you — as a built-in option.

Surf seamlessly across all your devices.

Not only does Safari come on every Mac, it comes on every iPhone, iPad, and iPod touch, too. And thanks to iCloud, your passwords, bookmarks, history, tabs, and Reading List are always up to date no matter which device you're using.

Discover something great. Then share it just as easily.

Safari makes it simple to find and enjoy the best of the web. And we've made it easy to share what you find with others.

Spotlight suggestions.

With Spotlight built into every Mac, you’re never far from the information you want. As you type in the Smart Search field, Spotlight suggestions display results from sources like Wikipedia, news sites, Maps, iTunes, movie listings, and more.

Share menu.

Share anything you come across on the web without leaving Safari. Just click the Share button, then choose how you want to send it off. Use Mail, Messages, or AirDrop. Tweet or post to Facebook. And even add comments and locations. A single sign-on sets up sharing to Facebook and Twitter, so you only need to log in once.

Shared Links.

Shared Links is the best way to see what’s up on the web. When you’re in the mood to read something new, quirky, or cool, open Shared Links in the Safari Sidebar, where you can view links from people you follow on Twitter and LinkedIn. You can scroll seamlessly from one story to the next, no clicking required.
