Replacement Trackpad doesn't work
I replaced the Trackpad with one from ifixit. The cursor is responsive however clicking doesn’t work, the Dock doesn’t respond or appear at all and I cannot open any menus .
I checked everything and even repeated the process and made sure the connections were secure.
I replaced the new with old and functionality returned other than drag and drop which is what prompted the upgrade in the first place.
Is this a good question?
