I just got a new MacBook Pro with Retina Display, this is my 1st Apple so I'm very new to the operating system. I have the touchpad set so I click with one finger, the problem I'm having is randomly when I touch the touchpad with my finger to click on something the arrow will jump to the left between an 1/8 to 1/4". It doesn't do it all the time it's intermittent. At times it jumps enough to where I have to move the pointer back to what I was clicking on and try again. Does anyone have any suggestions on what's going on? I have a bad feeling I got a dud. This is my 1st post and I'm sorry it's for help.
