Ever since I bought my Macbook pro in mid 2010, the trackpad hasn't been too clicky. About a year ago it stopped clicking altogether. I did take it to the Apple store twice, but they wanted to take it for five days- ******* that, I thought to myself, I can't live without it for that long of a period. My warranty is expired now, so I ordered myself some pentalobular/triwing screwdrivers and a new trackpad. The new trackpad does not click either.. it's not any clickier than the last, actually. I switched out the trackpads according to instructions on ifixit. I tried adjusting the pentalobular screw to make the trackpad more clicky, but that doesn't work either. I tried cleaning in that area of the computer to free it from debris. Any idea what I could be missing here? Thanks!
