I have just done a fresh install of mavericks on my pro book everything seems to be fine except in my about this mac it shows my display as 13 and it should be 15 how can i change this without causing any disruptions to other settings??
"macbook pro 8.1" is showing its just the display size thats the problem.
Any help thanks Montyboy
