Bought a MacBook Air Mid 2014 but system says it's Mid 2013
I bought a new customized Macbook Air (mid 2014) but when I look the hardware up in the system it says it is mid 2013. How do I ensure it is really the Mid 2014 version? And how do I update the system so it displays the rightmodel?
See the screenshot of the system info in attachment.
