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, for free. Open the App Store. In the sidebar, click Updates. Click Update next to an app to update only that app, or click Update All. If you didn’t get the app from the App Store on your Mac, contact the app developer to get help with updates.

Assuming you are downloading the software update or any app on your Mac. Launch App Store on your computer. If you are downloading any updates, click on the Updates tab.
