Actually, I do see something a little odd that I just noticed. I see references to “/Users/WonCheol” and “/Users/woncheol”. One has capitalized letters and one doesn’t. This is strange, as I would expect them to be listed the same, as they are in other diagnostics I’ve looked at.
What do you see when you run this command in a terminal session?
ls -al /Users
Can you think of any reason why I would see both versions?
