I have a BASE Mid-2012 MBP and would like to know about the graphics in the system. I am asking this because I came across a screenshot of the About this Mac window from Mountain Lion, which showed that the MacBook had Intel HD Graphics 4000 512 MB. Now when I look in About this Mac, it says that I have Intel HD Graphics 4000 1024 MB. Which is correct for the BASE MID-2012 MacBook Pro? And could anyone possibly give me a clue as to what caused this change? The only thing that I have done to the laptop between Mountain Lion and Mavericks is upgrade the RAM from 4 to 16 GB, but that wouldn't cause this, right? Thank you in advance.
