Hi, My macbook pro has been having issues with the trackpad/cursor. Every few hours (it can be completely random but this in on average), the cursor will start acting erratically. Basically moving and clicking on its own. I've taken it into the Apple Store but as this is a totally random issue it has difficult to replicate. They tried swapping out the hard drive first, now the trackpad and still no luck. I'm not sure where to go from here, i am still under warranty so does anyone have any suggestions. This issue hinders me from using my macbook as the cursor will act up for quite some time occasionaly and i'm not able to use it properly.
