Password is in a different language
I've had this happen with a couple of new Macs at our office recently.  I'm not sure if something is off with Apple's latest imaging of new Macs but the fix is relatively simple.


Login as normal, using your regular password.
Click on the  menu in the upper left corner and choose System Preferences (4th choice down)


Click on Language &amp; Region

Change the following


If English is already an option then drag it to the top of the list
Click the + symbol in the lower left to add English to the list of languages
Change the region to the appropriate one (Americas, North America, United States)






Click "Show All" to leave the preference pane and return to System Preferences.  Your language should now be set to English.  You might restart your Mac to make sure.
