My MacBook track pad was acting up. Unable to click, not very responsive to touch.
The repair process went smooth thanks for the useful detailed guide and all the tools and accessories provided by iFixit.com.
If the track pad just not clickable (or having trouble clicking), just need to readjust the little circle metal underneath the track pad, no need to buy the track pad, unless your track pad is not responsive.
