adjustment height screw type on trackpad?
I am trying to fix my trackpad not clicking anymore on a refurbished macbook pro 13" retina early 2013. I opened it up without any problem, but I can't seem to find the right screwdriver to unscrew the trackpad's height adjustment screw; a TR6 seem slightly too small and a TR7 too big. Do I need a special tool?
