Restart AFP service in High Sierra I would like to restart the AFP service but I'm not sure how to do it anymore. In previous versions of OS X I would run serveradmin stop afp and serveradmin start afp, but serveradmin is no longer available in High Sierra.
serveradmin is still available in macOS High Sierra. Server.app has to be installed though and launched at least once to start its set-up.

host:~ $user: which serveradmin
/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin

host:~ $user: sudo serveradmin fullstatus afp
afp:state = "STOPPED"
afp:readWriteSettingsVersion = 1
afp:logging = "NO"
afp:servicePortsRestrictionInfo = _empty_array
afp:startedTime = ""
afp:guestAccess = "NO"
afp:logPaths:errorLog = "/Library/Logs/AppleFileService/AppleFileServiceError.log"
afp:logPaths:accessLog = "/Library/Logs/AppleFileService/AppleFileServiceAccess.log"
afp:failoverState = "NIFailoverNotConfigured"
afp:servicePortsAreRestricted = "NO"
afp:setStateVersion = 2
afp:currentConnections = 0


AFP won't work with shared APFS volumes!
