I'm able to load the lisp in my system. After loading the lisp did you get the pop up like in the screen shot? and did the window show that the lt.lsp successfully loaded as shown in screenshot? If not the Lisp is not loaded. Try restarting the AutoCAD and see if it works. Though I am using windows I guess it should not look much different in mac.
