AFP

XBMC has AFP (Apple Filing Protocol) client support for media on all platforms. We don't recommend using it, as AFP support in Kodi is very buggy right now.

Using external drives
Beware: When sharing an external drive via AFP from within MacOSX Snow Leopard or MacOSX Lion keep in mind that only HFS+ formatted drives are shared. This is a restriction from Apple. You can't share FAT32 or NTFS drivers from within MacOSX! See: https://sonos.custhelp.com/app/answers/detail/a_id/505
