The status menu on y mac book air not showing...how can I fix that? Thank u!

System Preferences > Energy Saver > check Show Battery status in menu bar

Try:

1. restart your mac
2. repair permissions with Disk Utility
3. Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. OS X: About OS X Recovery
4. If that doesn't work, and you still can't get the battery status to work, I'd reinstall Mavericks over your current installation. Sort of a blunt tool but it will probably work.

Do the regular menu entries extend all the way across the menu bar? If so, the system will remove status menu items to make room for the actual menus.

If not, it could be a crappy third-party menu item causing the problem with the rest.

I'm having the same problem. It happened right after the most recent security update. If I click in the blank space they show up.

Anyone?
