Having multiple displays is definitely quite useful for creative types and people who like to multitask. Mac OS X Mavericks changed the way Mac OS X handled multiple displays, but this came with the addition of a menu bar on secondary displays. This additional menu bar serves some purpose but, as is often the case with new software features, not everyone is fond of this additional menu bar.
If you’re one of those users who find the additional menu bar on your secondary display annoying, or want to get rid of it because you just don’t have any use for it at all, rest easy. Mavericks does indeed let you disable this additional menu bar, and here’s how you do it.

Hide The Menu Bar On Secondary Displays
Normally, this is what a secondary display looks like on Mavericks. Note the slightly faded menu bar:
To get rid of the secondary display’s menu bar, you’ll have to go to the Mission Control preferences. You can do this by going into System Preferences or simply searching for Mission Control in Spotlight.
Once you have Mission Control preferences open, untick the option that says Displays have separate Spaces.
To have the changes take effect, you’ll have to log out and then log back in again. Once you do that, you should no longer have a menu bar on your secondary displays.
One thing to be aware of, though, is that disabling the ‘Displays have separate Spaces’ setting will also disable OS X Mavericks’ new multiple-display management features, so it will handle multiple displays much like previous versions of OS X.
So, if you like how Mavericks handles multiple displays, you might want to keep the setting enabled and live with the additional menu bar.
