![]() Using these ACLs on OS X are quite simple you may even be using them without knowing it.ĪCLs are made up of ACEs (Access Control Entries) and each ACL can contain more than one ACE. Mac OS X is no different and, as of OS X 10.4, it has supported NFSv4 ACLs when used with the HFS+ file system. Often times this is also dependent upon which filesystem is in use, or which implementation can be used on which file system (the two primary ACL types are POSIX.1e ACLs and NFSv4 ACLs). ![]() Most operating systems also support some form of Access Control Lists (or ACLs). For directories, these permissions mean that the user can read the contents of a directory (but not necessarily the contents of the files in the directory), can write to the directory (create and delete files), or execute (allows the user to traverse that directory tree in order to access files or subdirectories, although it does not on its own allow permission to see the contents of the directory). With a file, these permissions mean that the user can read the file, write to it, change or delete it, or execute it as a program. You can further define whether or not each of these has read, write, or execute permission to the file or directory. Standard POSIX permissions are independent of which file system they are used on (provided the system supports them), and anyone familiar with Linux or UNIX will be familiar with them as they are the standard way to set very basic access control on files and directories.Įssentially, you can define the owner of a file or directory, the group that owns it, and “other” (everyone who is not the owning user or a member of the owning group). Most UNIX systems use the standard POSIX (Portable Operating System Interface) permissions when managing access to files.
