Trackpad issue 1 out of 20 times, have to tap again.
I had that freeze problem, it has now been fixed with the last update.
The issue I'm having now is that the trackpad is super "slippery/smooth", so that some taps (not a click, but a tap with a finger) are not registered as taps, but rather as slight mouse movement. At least thats my theory.
What happens is that every now and again, I tap on a link, closing a window, or tap another tab, and nothing happens and I have to tap again.
This is especially the case when I tap on the edges of the trackpad.
Maybe its just me having to get used to the upgraded macbook pro's, but is alittle annoying.
MacBook Pro with Retina display, OS X Mavericks (10.9)
