Trying to download the Airport Utility App from the iTunes store. Found it; its free; clicked on it and it said it was downloading and than says downloaded. Can not find it anywhere on my iMac. Tried the same thing on my MacBookPro. Same thing; cant find it. Tried it on my iPhone; it asked me if I wanted to install it; I said yes. There it is gone! Whats up with this? Running latest version of iTunes and Mavericks.
