For some time now my Finder "Get Info" dialogs have been displaying "Fetching...", and I recently decided to fix the problem by following the instructions for resetting my home folder permissions. As expected, this resolved the issue, but now the permissions on all of my files are
-rw-r----- 1 MyName staff ... FileNow
whereas before they were
-rw-r----- 1 MyName MyName ... FileBefore
and I wonder: Why were they different before? Is there some common operation that causes permissions to change from the default, to what I had? Was the default perhaps different in earlier versions of OS X? Are there security implications of this change?
