In 20 years of using Apple devices, this is the first time a User Account I am dealing with has corrupted on me. I can’t imagine how much detritus it has.

How can I fix it, or lose the least amount of good stuff?

Above is what I want to address. Below is what has already been tried and how it presented..

Apple “Support” has fought me every step of the way, because it is Apple’s policy not to support Obsolete hardware, or Obsolete software. As far as the software, it is less than 5 years old., And the problem turns out not to be either the hardware or a unique or discontinued feature of the software. But we did after many reinstall, Recoveries from the Partition, Cmd R, or Recoveries over the Internet, Opt Cmd R.

We did finally narrow it down to the fact that my User account is corrupted. A new test administrator User worked properly.

I found an Apple article, I don’t remember the search term used, but here is how it presented:

Under SysPrefs/ Internet Accounts, only my iCloud and Game Center accounts show but none of my non-Apple email accounts. (Clue, long ago, on my MBP running 10.7.5, my yahoo accounts won’t appear.)

As a work around, I again created a new Admin User for myself, and all of the above seems to work properly.

Conclusion, my original User account is corrupted.
