Apple has deprecated support for Apple Filing Protocol in macOS Sequoia 15.5.
The year after Apple released the Macintosh in 1984, it introduced a proprietary networking standard called Apple Filing Protocol. Part of a suite of software which included AppleTalk, AppleShare, and Apple cabling hardware called LocalTalk, AFP allowed users to share files across Macs on local area networks.
This was a decade before the Internet and its open protocols became popular in the mid-1990s.
