Darn it. Doing the PRAM thing worked but only temporarily. ☹ï¸
I was afraid that might happen, because I had a date/time issue that the same procedure corrected, but which also regressed and required a second step to correct with finality.
Unfortunately, the second step, which used to be a simple Terminal command, has changed as per
Apple has changed resetting permissions again.
Redo the NVRAM/PRAM thing, and then follow steps 1-8 to repair home permissions.
Yep! Giant PIA!
