I'm fairly sure the problem is that the ls on the mac does not support the --colors option since it is a vanilla bsd ls and not the gnu version. Fish completetions reads the man pages on the machine to generate the completion options
ls -<TAB> correctly lists all the options for ls on my OS X box. I don't know if the detect bad options code works for utilties that only have single dash char options like the older version of ls on OS X. - Booker C.
