I have a 2012 MacBook Air and am getting quite a bit irritated with my trackpad. I like to double tap folders/files to open them but noticed the trackpad isn't very responsive to double taps. I usually have to tap like 3-10 times quickly and hope it opens the file and that I don't move the cursor off the file during my tapping spree -.- I remember it used to work perfectly, but I don't remember when the issue began. Recently I've been doing more work in multiple files and it's gotten really annoying trying to open them. Anyone have a fix for this? All other taps and gestures work fine.
