I recently purchased a new Macbook Pro (8,1 running OS X 10.7.3) and I am frustrated with the behavior of the 'two-finger' trackpad secondary click. I am used to the behavior of my 2006 Macbook, which I migrated form, where I could issue the secondary click command by holding one finger on the trackpad whilst tapping the trackpad with a second finger. However, this movement is ignored by my Macbook pro, which requires both fingers to be lifted and tapped simultaneously. I seem to have an appreciable error rate with the 'double tap' movement since it requires both fingers to hit the trackpad at the same time. I also find that it requires more energy! Does anyone know how to change the secondary click function to the macbook-like secondary click?
