Problem with Apple ID and SECD (security daemon?)
When I try to sign into my Apple ID (on App Store) with one of my accounts, the cursor spins forever. (This does not happen with the same AppleID from a different user-account on my 2017 MacBook Pro, nor from my iPhone.) Also, the security daemon (I think) SECD crashes randomly from time to time and puts up a crash report. This problem arose after I tried, with only partial success, to roll back my attempt to update to Monterey and return to High Sierra, which is what I am running now. The rollback was complicated because of what Monterey does to the disc structure, but with some guidance from the author of the backup software I had been using, and from whose clones I attempted to restore, I got back to a mostly-working High Sierra. From the SECD crash report:
Process: secd [18810]
Path: /usr/libexec/secd
Identifier: secd
Version: 1.0 (1)
Code Type: X86-64 (Native)
Parent Process: ??? [1]
Responsible: secd [18810]
User ID: 509
Date/Time: 2022-02-11 10:45:24.999 -0500
OS Version: Mac OS X 10.13.6 (17G14042)
I believe there is some corruption of my UUID or something like that, but I don't know how to correct/reset/ it. Any hints? I would be willing to create a new user account if there is some easy way to have it retain the contents (Documents and Mail, mainly) of the corrupted one.
