Hi, I was wondering if someone could explain what exactly the "Access Permissions" checkbox does? There doesn't seem to be much in the way of information in the manual or the built-in help. Ideally I would like to deny access to a folder on an NTFS drive for a specific user on the Mac. I can do this on Windows and I thought this option may give me similar functionality on OSX but I can't see how to specify users and/or groups on the Mac side so I am confused as to what exactly this option is doing. Thanks.
