The newest Apple laptops feature a glass trackpad that supports many useful gestures. Made of glass, it feels great and the whole trackpad is the trackpad button. You can press in certain areas to accomplish simple tasks like right-clicking, and the supported gestures are, I’m sure, only a precursor of what’s to come.
I received a few e-mails from customers asking whether the feel of clicking can be adjusted at all. They find that the noise from clicking is too loud, and that there’s too much travel in the mechanism for their comfort.
This is a rare hardware hint, and as such your mileage may vary and you’re wholly responsible for any damage that might be caused!
Start by removing the battery cover of your unibody MacBook or MacBook Pro. Remove the battery by pulling on the clear plastic tab – it’ll pop right out. You’ll notice a screw on the underside of the trackpad with a Y-shaped head. Using a small flat screwdriver, turn it clockwise about an eighth of a turn. I’d advise reassembling the unit, testing for the desired tactile feedback, and continuing or backing off as necessary.
Be sure not to turn the screw too far in one direction or the other, as you may either lose the screw or cause irreversible damage to the trackpad. Neither of these outcomes would be covered by your warranty!
