I'm not sure how to post an image in this forum.
Anyway, you can see what I mean by comparing the correct display. For example, if you have a look at the Hardware simulator instructions: http://www1.idc.ac.il/tecs/tutorials/hardware-simulator.pdf
In the "Running a script" section there are two screenshots. In the second one the message "End of script - comparison ended succesfully" is circled in red. This message is shown in a rectangular area at the bottom of the screen.
This area where messages are displayed that I call "status bar" and that's what's missing in my Macbook pro laptop. It happens in every tool, not only in the hardware simulator. It shows in my linux box just as in the tutorial screenshots.
I hope it's clearer now.
