gvim - macvim clipboard not working

Question

Installing macvim 7.4 already supports clipboard

gvim --version | grep clipboard

+clipboard       +iconv           +path_extra      +transparency
+eval            +mouse_dec       +startuptime     -xterm_clipboard

But after setting up

set clipboard=unnamed

No effect?
