Hello guys, I own a 15" MBPR mid 2014 that has a multi-touch trackpad. My trackpad worked fine since the last 3 months but it has started creating a problem. I use both, the soft touch on the trackpad as well as the physical trackpad primary click button for primary clicking. Now the problem is that the physical trackpad primary click button isn't behaving the way it is expected to be. When I press the primary button with normal force in the RED area as shown in the picture, the clicking doesn't occur. Whereas the primary clicking in the BLUE range and the secondary click in the GREEN range works perfectly. I also noted that there used to be a firm clicking sound whenever I physically pressed the trackpad buttons but now there is no clicking sound in the RED region, while the BLUE and GREEN regions work fine in terms of functionality and physical inspection. After restarting my laptop several times and disabling the Better Touch Tool app, I also found out that if I press the RED region with certain amount of force (which is greater than I previously used to apply when the trackpad used to work fine), the clicking occurs - but not with normal force. Please tell me what should I do to bring it back to the original condition as this is really frustrating for me because I miss a lot of clickings before I am finally able to click correctly. I started running Apple Diagnostic Tool but it doesn't gave me any problem. And I don't use any bluetooth or external mouse. Any help would be appreciated.
