Running Debian on an old Macbook 4,1 (2008) on my first ever Mac and am not thrilled with the trackpad, or the keyboard layout. The best configuration I've yet mustered is:

  #!/bin/bash
  synclient TapButton1=1
  synclient TapButton2=3
  synclient TapButton3=2

This gives a minimally usable touchpad, with two-finger-tap right-click, side-scroll and tap-select.

I am still scratching my head at the absence of right-click and the key layout. I have no actual Mac OS experience to compare to, but Imagine they've done it all well when it's used as intended. Otherwise, it's working great and the build quality is solid. I am already fantasizing about Linux on a newer model, maybe with a PC mouse or external touchpad though.
