Re-Download OS X Mavericks Installer on a Mac Running 10.9
If the Mac is already running OS X Mavericks, redownloading the installer is extremely easy.
Open the App Store and search for “OS X Mavericks” or just click the direct App Store link (free, downloading one times or 200 is always free)

This is obviously much easier than it used to be in prior versions of OS X, which required various Option+Click maneuvers which caused a lot of confusion and frustration with many users. A nice big “Download” button is easy and obvious, just remember to

It’s not entirely clear why some users encounter the corrupted download issue, but deleting the Installer and trying again seems to resolve it every time.
