I have a text file in /Users/Shared that I would like to be editable by all users on my Mac. The Get Info window shows that everyone has read and write access, and when I open the file with TextEdit on a non-owner account, the title bar does not state that the file is locked. Yet when I attempt to save my edits, I'm faced with the "The document could not be [saved / autosaved]. You don't have permission" popups.
I've tried adding the non-owner user to the permissions list in the Get Info window. No dice.
ls (with names edited):
$ ls -l /Users/ total 0 drwxr-xr-x+ 14 Guest _guest 476 7 Apr 11:14 Guest drwxrwxrwt 45 root wheel 1530 12 Apr 17:40 Shared drwxr-xr-x+ 15 fileowner staff 510 22 Feb 12:49 fileowner drwxr-xr-x+ 17 admin staff 578 21 Dec 10:55 admin $ ls -l /Users/Shared/Links.txt -rw-rw-rw-@ 1 fileowner wheel 619 25 Feb 19:44 /Users/Shared/Links.txt
I can reproduce this behavior on two separate machines, one running 10.8 and the other 10.9, but not on the one running 10.6.
