I've got a Macbook Pro Retina 13" with Mavericks installed and the Touchpad is not responsive and sometimes I have to click up to ten times before it will recognize my click. I removed the tap-to-click and I really have to press the touchpad.
I've used the exact same setup on my previous Macbook Pro (non retina) without issues.
Is there something I can reset myself before contacting Apple? I've bought this Macbook just a bit over 3 months ago - so the Apple Care you get by default is no longer valid.
As my search online I've found a fix, but this fix is not written for my software it claims on installation: http://support.apple.com/kb/DL1704?viewlocale=en_US&locale=en_US
