So I changed my menu bar to black and replaced the menu bar icons but now for some reason my airport menu bar icon does not show up anymore. I'm not sure if the aiport.menu was fully copied for it to work since when I tried copying the icons, all of them copied except the airport.menu because I got a message saying "Cannot copy because it is in use". So I deleted the file and copied the new one. So then I check on System Preferences > Network and check where it says "show airport status in menu bar" but it doesn't let me click on apply, it's greyed out. So when i exit System Preferences and go back, it's unchecked again. Any help?
