Hi, I have upgraded my Macbook Prod 13 Early 2011 with Mountain Lion. Now scrolling between pages in Launchpad & Scrolling between Desktops and on some websites in Safari is not smooth at all. There is a lag while scrolling. My Macbook specs are i5 with 4 GB RAM. I have shown this issue in Apple genius bar appointment they said to wait for next OS upgrade. Could you please suggest is there anything i can do to resolve this issue. It is very annoying.
