I logged back into my Win-laptop Monday and spent a couple of hours getting the frisbee up to speed. I downloaded all the current anti-malware definitions, then I turned to those critical Microsoft updates again. I manually selected just the titles that looked appropriate to my setup to avoid the 94% problem. Still feel irked that I had to waste so much time.
Last night I installed an update on my Mac. I got an email alert that it was available; a dialog box prompted me to enter my pass; I kept working. When the update was completed seconds later, I closed the notice dialog. Such a breeze. Guess I’m just spoiled by my trusty OSX software.
