hi everyone, I've searched this issue across forums and quite a lot of people using different apple machines seem to have the same problem about the tap to click, so I would to bring this issue up again. My macbook pro 15 is about a month old, about 2-3 days ago, I realised that the tap to click stopped working occasionally, after a few tries, it did work again but it's very annoying, so I now switched back to the mouse click. The drawback of using mouse click is that it's very noisy if you are in library or at a quiet office. Is there anyone having the same problem? Is it a hardware (trackpad) issue or software (OSX) issue? Thanks!
