>The MacBook Pro keyboard mechanism has had a materials change in the mechanism. Apple says that this new keyboard mechanism composition will substantially reduce the double type/no type issue. Apple will not specify what it has done, but doubtless tear-downs of the keyboard will reveal what has been updated.
They say it's improved. But check back in a year or so to see if it works, because the 3rd gen revisions didn't end up fixing it before.
If you have a 3rd gen butterfly keyboard, replacements will now use the 4th gen.
If you have a 1st or 2nd, they'll continue to replace the failing keyboards with more failing keyboards. Lucky me!
In other news for the 2016 MBP, there's a new repair extension program for the "Oops we made the display ribbon cable too short" issue. Haven't had that problem myself, but this was an expensive goddamn laptop and I'm not optimistic about its resale value or lifespan after the 4 year repair window is up. Multiple known design flaws that cost $600-$800, and in the keyboard's case are just putting in more of the same failure-prone parts.
I might bite if they've fixed this. Oh and no touch bar.
