Greetings! Just got my first Mac, a second hand MBP13 2010 and am very happy with it. However, I'm looking for a way to rotate the built in screen 90 degrees (for lazy web browsing, half asleep on the side...). So far I have only found info on how to do this on external monitors and with a ATI graphics card (the MBP 13 2010 has Nvidia 320m). Is there some unofficial hack or other way to enable this feature? Thanks!
