After I have worked hard with the language management into my OS X I tried to resolve some issues the first issue is the OS X should running English instead of Danish, this resolved I do that go into the (System Preferences -> Language & Text) here inside click (Edit list …) and remove all the languages you not want be listed, remember if you run more than one language so dreg’n'drop your language up to the top.

Followed you must restart your Mac after you have restarted your Mac, you will discover the login display is still appears on your first language that your Mac are installed from the beginning in my case Danish, that we would not therefore log in and open up your terminal can be found in the folder (Applications -> Utilies) now open the “terminal” write follow and be sure you have adminsitartor promissons.

sudo languagesetup

Here after you will be ask for your super administrator password that you need write, then it tells your now it all as it should be and you may now reboot your Mac before you do anything else.

Good luck with this small tip.
