I'd like to change the tap (i.e. touch) sensitivity value. Under a synaptics brand pad on a PC you would have the option of adjusting a slider from "light touch" to "heavy touch". It's not the com.apple.trackpad.scaling setting, this is speed. I have already tried BetterTouchTool and MagicPrefs, neither are the solution I'm looking for, however one of them DID increase the sensitivity and make tap to click work properly. Unfortunately it also removed standard tap-and-drag functionality (overrides sysprefs). It did show me that this is not a hardware issue, and indeed can be changed through software somehow, but I'm not sure how. Late 10 MBA on 10.6.5 Appreciate any help.
