I think my MacBook might have a software bug with the trackpad - occasionally, but not always, when scrolling or just moving the cursor around I'll hear a slight clicking noise. It's a higher pitched sound than the regular press/force press feedback. I haven't been able to work out any pattern in what causes it, seeing as it only happens sporadically. Super annoying. I think I read that El Capitan will have an option to turn off all trackpad noises, so that might fix it, but I'd rather have the option to still have the normal clicking noises (if this indeed is a bug). Anyone else have a similar experience?
