I was just looking thru the commandline switch options and noticed that the -rt switch "needs root privledges". Well, if this is true, I did try a couple of examples (from Adam Lindsay, in conjunction with Paradiddle) that used the -rt switch, but it did not ask me for a password.
Well, it's just guessing, but doesn't the default user under OSX have root privileges anyhow (even if she/he is not "root")?
