Mac OS X 10.7 Lion
Multi-Touch gestures transform the way you interact with your Mac, making all you do more intuitive and direct. Now an even richer Multi-Touch experience comes to OS X Lion. Enjoy more fluid and realistic gesture responses, including rubber-band scrolling, page and image zoom, and full-screen swiping.
OS X Lion offers systemwide support for gorgeous, full-screen apps that use every inch of your Mac display. You can have multiple full-screen apps open at once - along with multiple standard-size apps. And it's easy to switch between full-screen and desktop views.
Mission Control brings together full-screen apps, Dashboard, Expose', and Spaces in one new feature that gives you a bird's-eye view of everything on your system. With a single swipe on the trackpad, your desktop zooms out to Mission Control. Think of it as the hub of your system: View everything and go anywhere with just a click.
The best way to discover apps for your Mac is now on your Mac. Just like the App Store on iPad, the Mac App Store lets you browse and download thousands of free and paid apps that you can start using right away on all your Mac computers authorized for personal use. New apps install in one step right to Launchpad, and the Mac App Store keeps track of your apps and tells you when updates are available.
Launchpad gives you instant access to all the apps on your Mac. Just click the Launchpad icon in your Dock. Your open windows fade away, replaced by a display of all your apps. Arrange your apps any way you want, group them together in folders, or delete them from your Mac with ease. And when you download an app from the Mac App Store, it automatically appears in Launchpad, ready to blast off.
Now apps you close will reopen right where you left off, so you never have to start from scratch again. And when you install software updates, you no longer need to save your work, close your apps, and spend valuable time setting everything up again. With Resume, you can restart your Mac and return to what you were doing - with all your apps in the places where you left them.
It's time to stop worrying about saving your work. Because now your Mac automatically saves what you're working on so you don't have to. It's not just an improvement for OS X, it's an improvement for anyone who's ever lost hours of hard work after forgetting to press Command-S.
Versions is a new feature that charts the history of your documents, taking snapshots in time, and displaying them side by side with the latest versions in an easily browsable timeline. You can review the past iterations of your compositions, restore a previous version, or copy and paste from old versions to new ones.
Looking for a fast way to share files with people nearby? With AirDrop, you can send files to anyone around you wirelessly - no Wi-Fi network required. And no complicated setup or special settings. Just click the AirDrop icon in the Finder sidebar, and your Mac automatically discovers other AirDrop users within about 30 feet of you. To share a file, simply drag it to someone's name. Once accepted, the fully encrypted file transfers directly to that person's Downloads folder.
