Apple Thoughts: Here's How The Mac App Store Updates Work

"How do software updates for purchased apps work? That's among the many questions users have about the Mac App Store. With the Mac App Store just over a day old, updates for purchased apps are already appearing in the Store."

The unknown is now not so unknown as some updates are coming through the Mac App Store already. It is probably not a big shock to find out that it is similar to how the iOS App Store updates your mobile device. Go into the App Store and you will see a notification icon with the number of apps that need updating. Click on it and you go into a screen very similar to what you see with your iOS updates. I didn't think it would be much different but in case you were wondering, well, now you know.
