APFS: AFP is incompatible with sharing of APFS volumes but is still usable as a Time Machine destination in High Sierra.Įarly implementations of AFP server software were available in Mac OS starting with System 6, in AppleShare and AppleShare IP, and in early '1.x' releases of Mac OS X Server.Single sign-on using Kerberos requires AFP 3.1. AFP 3.0 and later is required for network home directories, since Mac OS X requires POSIX permissions on user home directories.Typically, Mac OS 9.1 or later is recommended for connecting to AFP 3.x servers for versions of original Mac OS prior to 9.1, installation of the AppleShare client 3.8.8 is required. For example, the maximum file size in Mac OS 8 is 2 gigabytes. Computers using classic Mac OS can connect to AFP 3.x servers, with some limitations.Mac OS X v10.4 and later eliminates support for AFP servers that rely solely on AppleTalk for communication.Notable current compatibility topics are:

Other literature may refer to AFP as 'AppleShare', the name of the Mac OS 9 (and earlier) AFP client. For this reason, some older literature refers to AFP as 'AppleTalk Filing Protocol'. Still earlier versions rely exclusively on AppleTalk. Many third-party AFP implementations use AFP 2.x, thereby supporting AppleTalk as a connection method. The AFP 2.x family supports both TCP/IP (using Data Stream Interface) and AppleTalk for communication and service discovery. AFP supports Unicode file names, POSIX and access control list permissions, resource forks, named extended attributes, and advanced file locking.ĪFP versions 3.0 and greater rely exclusively on TCP/IP (port 548) for establishing communication, supporting AppleTalk only as a service discovery protocol. The latest version of Apple's OS at the time of writing, macOS Ventura, is still able to authenticate with and connect to AFP servers. Starting with OS X 10.9 Mavericks, Server Message Block (SMB) was made the primary file sharing protocol, with the ability to run an AFP server removed later in macOS 11 Big Sur. In OS X 10.8 Mountain Lion and earlier, AFP was the primary protocol for file services. The Apple Filing Protocol ( AFP), formerly AppleTalk Filing Protocol, is a proprietary network protocol, and part of the Apple File Service ( AFS), that offers file services for macOS, classic Mac OS, and Apple IIs. Apple Filing Protocol Communication protocol Not to be confused with Apple File System (APFS), a file system for macOS, iOS, tvOS and watchOS, currently being developed and deployed by Apple Inc.
