The Mac App Store revolutionizes the way applications are installed on a computer — it happens in one step. Enter the same iTunes password you use to buy music and apps on your Mac, iPad, iPhone, or iPod touch. Within seconds, your new app flies to Launchpad, ready to go. So you can spend more time enjoying new apps and less time installing them.
Since developers are constantly improving their apps, the Mac App Store keeps track of your apps and tells you when an update is available — including OS X software updates. Update one app at a time or all of them at once. You can even have your apps update automatically, so you’ll always have the latest version of every app you own.
Can’t open a file you’ve downloaded or received in an email? OS X can search the Mac App Store to find the app that can open the file. Buy what you need instantly and get back to business.
You can install apps on every Mac authorized for your personal use and even download them again. This is especially convenient when you buy a new Mac and want to load it with apps you already own.
