One-click app installs, easy updates and more for all your favorite Mac apps, the Mac App Store is now open for business. If you are running Snow Leopard fire up Software Update and you should see it. If you have no idea what I’m talking about, it’s basically the iPhone/iPod/iPad App Store, but on your Mac…. for Mac apps (not iOS apps). Just an “easier” way to manage the apps that are installed on your Mac computer.
