macOS: persistent home lives at /Volumes/vmix-home/<user> (no mount over /Users)

Browse source 
macOS refuses to mount a volume over /Users (firmlink), and a failing fstab
entry also suppresses the automount. Point NFSHomeDirectory at the automounted
volume instead. Profile: Dock entries need tile-type/file URL; wait for the
wallpaper store before shutting down.
