I recently got the new touch bar 13" MacBook Pro, and within a couple of weeks I started noticing that the "C" key was having response issues. Sometimes it would work fine, but most of the time, hitting this key wouldn't register unless I tapped it much more forcefully than other keys. I finally got tired of dealing with this, so I took it in for a genius bar appointment last night and walked out with an entirely different machine (apparently they didn't have the ability to do the repair in store yet, so it was easier for them to just exchange it). On this brand new machine, I'm noticing that the "X" key is now having issues. Frequently whenever I hit this key I end up with two "Xs" being typed. Interestingly, I overheard another guy at the Apple store last night who was having a very similar problem -- whenever he typed the spacebar he would end up with two spaces. Has anyone else noticed similar issues?
