MacOS – Macbook sees Japanese keyboard instead of native US English

keyboardmacmacbook promacos

Mavericks on Macbook Pro Retina A1398 (US keyboard with horizontal Enter) shows Japanese keyboard (JIS, with vertical Enter) on enabled keyboard viewer. How do I make Mavericks to recognize and to show its native US Keyboard layout?
I have tried to reset SMC and PRAM with no success.
p.s. I have tried changing input sources to U.S. as well – does not change the orientation of return on bluish keyboard on the right – mac OS still thinks I have JIS…

It sounds like your machine is not recognizing the "keyboard type" correctly, thinking you have a JIS (or ISO) type instead of ANSI. See this article for some suggestions on fixing it:
