Fixing Sticky or Crunchy Keys?
The keys on the left side of my Mid-2015 MacBook Pro have gotten to where they stick or make an odd crunching sound when pressed. It doesn't happen consistently and there doesn't seem to be a pattern to it. The keys work just fine, but I'd like to get it taken care of before passing the machine on to a friend when I do an upgrade in a few months.
Is there something I can do at home to clean/fix this issue?
