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?

Note that staff isn't even a group I'm in (I'm in admin). I'm not sure what the implications of that are, or who ends up in that group. – raxacoricofallapatorius Feb 5 '13 at 20:30
that is because you have admin rights. a normal user is in staff – Mark Feb 5 '13 at 20:54
ALso note that the Apple note to rename users only includes OSs up to Lion - so not ML - take note of what details are on a article - I don't know what if anything ML has changed or if the note just has not een updated.. – Mark Feb 5 '13 at 20:58
@Mark: Good point. I followed these (same) instructions, which mentioned ML explicitly. – raxacoricofallapatorius Feb 5 '13 at 21:11
