With the Mac App Store you can buy and download apps directly on your Mac. To download and purchase apps from the Mac App Store, you need to sign in with the same Apple ID you use on the iTunes Store. If you don't have an Apple ID, you can create an account at My Apple ID (appleid.apple.com).
Note: If you have an existing credit balance on your iTunes Store account, that balance will be shared across the iTunes Store and Mac App Store.
Browsing for apps
If you already know what you're looking for, you can search for the app name using the Search field in the upper-right corner of the Mac App Store. Your search results will be displayed after you press Enter or Return. You can also browse apps by categories such as games and productivity,
You can sort your search results by Relevance, Most Popular, Release Date, and Customer Rating using the Sort By function located just below the Search field. You can read app descriptions, user reviews, and view screenshots for any app.
Purchasing an app
When you find an app that you like, click Buy (you may be asked to sign in with your Apple ID). For more information about Apple ID, please see this article. When you click Buy, the app will begin downloading automatically, and the app icon will be added to your Dock with a progress bar below the app icon. Once the app is done installing, the progress bar below the app icon will go away.
