The user-group security model is alive and the heart of OS-X  
security.  It is used throughout the system even within the user's  
home directory where there are files the user cannot access.  This  
causes problems for backup progrms that want to be run by the user  
with a window interface as they can't backup those files.  ACLs are  
available but not used by default.  The user has to create them if  
desired.  There used to be a FreeBSD project to add ACLs but I don't  
know its status.  i suspect the two implementations will be very  
similar.
