While Windows uses access control lists (ACLs) exclusively to enforce security, the Macintosh uses any one of three different schemes: Mac-style folder permissions, UNIX permissions, or ACLs. Regardless of what scheme the Mac is using, Acronis Files Connect (formerly ExtremeZ-IP) must map the Windows ACL to each of these Macintosh schemes in order to provide the necessary file and folder security expected by the user and/or application.

Acronis Files Connect versions 10.0.4 and later have been tested for compatibility with macOS 10.12 ‘Sierra’. If you are running an earlier version of Acronis Files Connect, please install 10.0.4 or later to support Sierra client Macs.


With Windows, the firewall is on by default. If you choose to run your server with the firewall up, you will need to configure it to allow other computers to access Acronis Files Connect (formerly ExtremeZ-IP).


With the release of version 10.5, Acronis Files Connect (formerly ExtremeZ-IP) supports Mac computers access to Microsoft Distributed File System (DFS) file shares in two ways.
