should i feel stupid for asking?

I know other people have had this problem...but im a mac person..so it makes it more complicated usually. Anyways I was wondering if there was any way to get rid of the lil black bars on each side of my screen when I play cod...

Find out what your desktops resolution is set to, then set the game to the same. Sometimes it's just as simple as that. Let me know if that fixes anything. If it doesn't I'll come up with something else.

I would think the same console cmds would work for your game as a pc game. But I'm not sure.

EDIT:

1. Open System Preferences and click Displays to display its preferences.
   
2. Click the Display tab; your display's supported resolution settings are listed in the Resolutions pane, from the lowest to the highest resolution.
   
3. Select any of the choices to change the resolution. A lower resolution gives you less desktop space to display windows and interfaces, but these will also appear larger. A larger resolution maximizes your screen space, letting you see more of a photo or document, and can help you manage applications whose interface elements span multiple windows.
   
4. To adjust your screen's brightness, move the Brightness slider left to make it dimmer, or right to make it brighter.
