Chosen Solution
I changed my trackpad and battery ( it was swollen) on my macbook pro mid 2012. Now the new track pad does not work properly. Its not sensitive at all u need to push and hold the finger for it to respond but when i warm it up with my hand or hair dryer it gets alot better almost as good as it was before. What can be the couse of this? Maybe a lose cable or ribbon? Please help me
@navid, There is a centre screw at the “bottom” of the trackpad that needs to be loosened or tightened. If you are like me (in the past) and tightened it too much, there will be no “click” effect. Image is courtesy of iFixit with my edit in ORANGE.
