Using Command line in Rhino for Mac

I a new to Rhino for Mac and am trying to used the Command line. My problem is I cannot seem to add parameters to a command. And commend history just shows me the name of the command an not the parameters. Manuals and other training available implies that this is available in Rhino for Mac but I cannot get it to work, Any help would be most appreciated.

Suzanne, the “command bar” (actually, Command Search) in Rhino for Mac is just for searching and launching the command. Options can be selected from a floating panel.
