I put a fair amount of effort into a long-ish blogpost yesterday, but I lost it due to my stupid Keychain problems. I’ll try to reconstruct it this afternoon.
I did what I should’ve done a couple days ago: I went to my user Library folder, found the folder at ~/Library/Keychains, deleted the folder, and cut loose. Now I have to re-enter all the passwords I had stored, but my system is astoundingly more stable.
