Give 3 things:
1) The creation date of many of the items in your ~/Library (yesterday & today)..
2) The lack of folders that I would expect to see in a Library folder in use for a couple months..
3) The issues that you've described..
I'm going to have to go with this assessment:
When you were using Transmission, you accidently overwrote (or something similar) your own Library folder with someone else's when you were downloading with Transmit.
Were you using FTP or SFTP to copy stuff from someone else's Mac?
At this point, there's no 'going back', so you're going to have to rely on your last good backup to fix this mess.
I guess that could be the cause. I was attempting to download some files (music and art files for a CD release) from someone else's FTP but Transmit hung up before I actually started downloading anything so I Force Quit.
Before doing that, I did get a weird message from Transmit that, unfortunately, I didn't read closely because I was distracted by someone in my office. I think the message had an "X" in it. XPanel or XFilter, I don't know. I'm kicking myself for not reading that closely.
It gave me the option to Stop or Continue. I guess maybe I hit continue and that's what screwed me.
In fact, that must be what happened b/c, in my Finder, the file I intended to download to is just above the Library.
I'm just not sure why it actually overwrote all of that.
At least I've got a fairly recent backup. I'm just bummed I haven't Time Machined recently.
Would comparing my HD to my b/u and moving any missing files from the b/u to the HD, then restarting, solve a lot of this? Or is there more to it than that?
Thanks (again).
