how do desktop files get locked spontaneously? (v10.7.4)
Recently (in addition to other seemingly unrelated password problems), files on my desktop became locked. Finder asks for a password to delete them. I believe an Apple Genius said thought this was normal behavior, but we've never had that happen before on this computer (Mac intel core 2 duo v10.7.4) or anyother of our Apple computers, which are several years old.
So, is this suspicious activity, or is this a normal feature of the OS?
I had a Comcast tech run me through a security check on our home wireless system. He thought it seemed secure. I should note that I'm mot sure how good he was, as our Time Machines have not worked since his "help".
