OS X Mountain Lion

Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac. It delivers the most intuitive and integrated computer experience. And it has iCloud built in, so you can access the content you use every day across all your devices.

iCloud:-

iCloud is how a Mac, iPad, iPhone and iPod touch work together.1 It keeps your mail, calendars, contacts, reminders, documents, notes and more up to date wherever you use them. So when you add, delete or change something on your Mac, it also happens automatically on your iPad, iPhone and iPod touch. And vice versa. You don’t have to do anything at all — iCloud is automatic. Just sign in once with your Apple ID and iCloud is set up in all the apps that use it. Suddenly, life’s easier to juggle.

Organise your life on your Mac. It’s all in a list. More than one, in fact. Make as many lists as you need and easily add to them. Set deadlines and you’ll get alerts as they approach. Set a location from your Mac, and your iPhone or iPad will remind you when you get there.2 Tick items off your lists as you go, and keep track of what you’ve completed. iCloud keeps your reminders up to date on your Mac, iPad, iPhone and iPod touch, so you don't forget anything.

Notes is designed for whatever’s on your mind, wherever you happen to be. Think it up. Jot it down. Make it even more noteworthy with photos, images and attachments. You can add, delete and flip through your notes, or do a quick search. Use the Share button to send your notes with Mail or Messages. Pin important notes to your desktop so they’re easy to get to. And take them with you everywhere. Notes works with iCloud, so when you create or edit a note on your Mac, it automatically updates on your iPhone, iPad and iPod touch. And vice versa.

Messages with iMessage takes your conversations even further. Because now you can send messages to anyone on an iPhone, iPad or iPod touch running iOS 5 too. Messages appear on your Mac and any device you use, which means you can say hi from your Mac and keep chatting on your iPhone or iPad, no matter where you are. Send photos, videos, documents and contacts — even send messages to a group. You’ll see when your message has been delivered and when someone’s typing a reply. Turn on read receipts and they’ll see when you’ve read a message. With end-to-end encryption, your messages stay safe and private.

Something new is always popping up somewhere on your Mac — an email, a message, a software update, a calendar alert. Notification Center makes it easy to stay on top of it all. Notifications always appear in the same spot on your desktop and disappear quickly so they don’t clutter up your screen. Whenever you want to see all your notifications in one place, just swipe to the left from the right edge of the trackpad. And there they are, in a simple, ordered list. So you’ll always know what’s up as soon as it comes up.

When your Mac goes to sleep, it still gets things done with Power Nap.3 It periodically updates Mail, Contacts, Calendar, Reminders, Notes, Photo Stream, Find My Mac and Documents in the Cloud. When your Mac is connected to a power source, it downloads software updates and makes backups with Time Machine. While all that updating is going on, the system sounds are silent and no lights or fans come on, so nothing disturbs you. And when your Mac wakes up, it’s ready to go.

You’ll find the Share button throughout OS X Mountain Lion. It’s the new, easy way to share straight from the app you’re using. Share photos, videos and other files with Mail, Messages and AirDrop. Send links from Safari. And with a few clicks, post straight to Facebook, Twitter, Flickr or Vimeo when the moment strikes.

OS X Mountain Lion is designed for tweeting. Sign in once and you’re all set up — and you don’t have to leave the app you’re in. Tweet links and photos directly from Safari, iPhoto or Photo Booth with the new Tweet sheet. Add comments and locations. And when someone mentions you in a tweet or sends you a direct message, you’ll get a notification right there and then. You can tweet from Notification Center too.

With the Game Center app on your Mac, you can play anyone on a Mac, iPad, iPhone and iPod touch.4 Just use your Game Center account from iOS or create one with your Apple ID. Then sign in and you’re in. See all the games you’ve played and get one going quickly. Check out leaderboards and see how your high score ranks against scores around the world. Even share your scores on Facebook and Twitter. Game Center recommends Mac games and opponents, so you can start a multiplayer game with your friends and even challenge people you don’t know.

Gatekeeper helps protect you from downloading and installing malicious software on your Mac, no matter where your apps come from. And it gives you even more control over which apps you install. You can download and install apps from anywhere on the web, just as you always could. You can choose to download and install apps from the Mac App Store — the safest place to find apps for your Mac. Or use the Gatekeeper default option, which allows you to install apps from the Mac App Store and apps from identified developers. It’s a new way OS X keeps your Mac safe.

New features in Safari make browsing the web smarter and faster. Now there’s one simple search field for both search terms and web addresses. As you search, Safari always stays one step ahead. It suggests a Top Hit, popular search terms and pages from your bookmarks and history to help you find a web page fast. Tab View shows your open tabs. Just pinch to see them all and swipe to switch between them. When you open web pages on your iPhone or iPad, iCloud Tabs makes them available on your Mac too.5 So you can pick up browsing wherever you left off. And now that Safari saves entire web pages in your Reading List — not just the links — you can catch up on your reading even without an Internet connection. Safari delivers the fastest JavaScript of any browser.6 So you get the best of the web.

OS X Mountain Lion brings all-new support for many popular Chinese features and services. The new Chinese dictionary and improved text input make typing in Chinese easier, faster and more accurate. With eight new fonts, your writing can appear formal, informal or fun. Mail works with QQ, 163 and 126. Baidu, the leading Chinese search provider, is a built-in option in Safari. Now you can post to the web straight from the app you’re in. Post videos with Youku and Tudou. Post to Sina Weibo, the popular microblogging service. And share easier than ever. All these new services are easy to set up on your Mac.
