I have owned several Macbooks, and have never had this issue: on the 13" rMBP I am getting thumb pain from clicking on the trackpad. Has anyone ever heard of this?
Thanks for the suggestion. Has anyone else experienced problems with this? It is actually getting so bad (I don't like using tap very much) that I am considering replacing it.
Try some Tylenol first if that doesn't work turn on tap to click. And set the 2 fingers to right click in the corner so you don't click when trying to scroll.
