It downloads fine and then sits there "installing" forever. It gets to about a minute remaining and then goes back to 7 minutes remaining and that's where it seems to get stuck. I then downloaded the dmg file straight from Apple, deleted Xcode.app and the dmg version installed fine, but I would prefer to have the version from the store, so I deleted Xcode.app again and retried the App store version with the same result. I don't want to have to delete the preferences and all of the other stuff that's not in the Xcode.app bundle. Any ideas? This is all on the latest version of El Capitan.
