AFS, the Andrew File System, has kernel support. [0] AFP, the Apple Filing Protocol, is a network protocol, not a filesystem. It has several userspace implementations. [1] AFS, the Apple File Service, is AFP plus other auxiliary protocols. [1] APFS, the Apple File System used in modern MacOS, has read only support in userspace, and there is work on a read/write kernel module that is not mainlined. [2] [4] HFS, the Hierarchical File System used in older MacOS, has mainline kernel support.
