Thanks Vincent, You're suggestion fixed the script. The top line is the original rubycocoa line and the line below the macruby equivalent. It would be nice to add such an example to the tutorial at http://www.macruby.org/trac/wiki/MacRubyTutorial (please kind maintainer--if you are listening). It is not obvious that macruby would require quotes and a trailing colon when passing the name of a selector/method. I don't think there are any examples that cover this rule currently. Thanks, Tim
