Ok so I have a MacBook Pro and I've been having this particular issue for a few months now. Out of nowhere an entire section of my keyboard stopped responding. The weird thing is that when I login to my MacBook the keys respond and when I use those particular keys as shortcuts they also respond then too. They stop working as soon as I try to type normally. So I was wondering if anyone knew what the issue is, and if it is something I can fix myself or take it to be fixed and if possible the typical price range for that kind of repair. Thanks for the help!!
