Eric: You're right; I was looking at Login Options. Now, I've unchecked all three Login Items.
In addition, on similar boards from early MountainLion upgrades back in July 2012, I discovered
advice to NOT connect BLUETOOTH devices before power up. I'm trialing that now with my Magic
Mouse and Apple Wireless Keyboard; I should have mentioned those BLUETOOTH devices early
in my discussion here; Sorry!
Thanks, your guidance has led me to search Google for titles not found on my original post here.
There's plenty of fundamental troubleshooting and maintenance information available out there.
I'll progress slowly with any repair mechanism. I've been spoiled by more than three years of
simple problems to solve since switching from Windows to Mac. Therein may lie the problem for
Mac newbies; we don't have much trouble to resolve so we relax and don't bother to use Apple
Tutorials. I'll get back to my habit of Scientic Method for user knowledge. It's been easy to be
lazy with my Apple products up to now.
