on an early usbC MacBook Pro we are noticing an odd keyboard issue: for select keys, two so far, the mighty "space bar" and the '7' key. These keys seem to stop functioning all together or loose their mechanical feed back. A couple of days later the keys work fine like nothing ever happened. Just makes probable a password will not function, you will get locked out of the device or function. anything can happen but usage is in a super clean work environment. maybe its how i am hold it or need to trim my nails?
