How to change lower case am/pm on the menu bar to uppercase? I find the time shown on the menu bar on mavericks a bit annoying. It's not perfect. The "AM/PM" is now shown in lowercase after upgrade to OS X 10.9 Mavericks. Back in the previous versions of OS X, it was displayed in uppercase. 

Is there a way change the lowercase am/pm to uppercase?
Since my system is german, I'm not 100% sure, but try this:


go to 'Language &amp; Region' in the System Preferences





open 'Advanced Options'





go to tab 'Time' and see if you can customize the way it's displayed
