In doing some more reading online re: this problem, is was posted on the web that one should have in Finder preferences, CD's, DVD's, and iOS Devices option checked - which I did - on my Mac and my wife's. So I unchecked the option re-started Finder and checked the option and still nothing - same issue - update not recognized. So leaving the option checked, I then unchecked Bonjour Devices ( which im not sure why it was checked to begin with). I restarted Finder and tried the update via USB again and it worked. So doing one or both of these tasks fixed the not being able to recognize updates issue....
