MBP Late 2016 — Butterfly keyboard's key double hit problem

I recently got a new Macbbook Pro. Problbem is what you're exactly seeing here and it's specific to the bb key.

I touch it once and it puts two b characters for me most of the time, but not always. This key is much looser and more sensitive than the others.

Suggested by @pydev, I removed the key cap. It does work flawlessly without the key cap. But when I put it back, same old story.

Any ideas?

Update: Here's a software solution working around the problem.

Update: Apple has announced a MBP Late 2016 — Butterfly keyboard's key double hit problem for macbooks with butterfly keyboard.

I'm experiencing this issue as well!

由完成的

I'm experiencing this very thing. I noticed that when I tested it out in Microsoft word, I just typed in B again and again until it doubled.

I tried to press the button with the same intensity each time, and sure enough, after the 3rd try b bb << (Second attempt there) it automatically populated as double-b... I'm not sure how to explain this in CPU terms. But it seems to be a key that is out of whack in general throughout the OS.

Would love to hear if there's a solution and how customers can update our CPU's.

Cheers,

thomasbunn - You'll need to bring your system in to an Apple Store for them to replace the keyboard. There is a known issue within the first gen units.

As far as upgrading the CPU sorry guy no can do! Apple uses soldered CPU's & RAM in all of their current laptops, you can't swap it out.

Ah, weird that it's the bb key for you, too! That'd be organized conspiracy!

I'm currently living in a US-sactioned country; Iran and thus I don't have easy access to Apple service center. Please do me a favor and update me about the results, if you decided to go down that way.

由完成的

I googled and found many people facing similar issue. Apple have replaced their keyboard's logic board.

I have apple care covered for 3years.. So I planned to visit the service center in 10days. Will surely update the status here.

Hi, how did that go for you? I see that Apple now has a recall as of June 2018 (which is after your issue). I was wondering what they do to test your computer for the problem because surely they have to believe us. They could not replicate our typing, nor believe screenshots we take.

I also had this problem same key "b", but by busting big B button beyond abode button behavior be back! i.e. I removed the button and then replaced it. It didn't seem dirty. Must have been out of alignment or something.

I had the same problem. Brought to the Apple Store, they ran a software diagnosis after hearing complaint (I also had problems w/ space bar being "dead" and the f&w keys not working intermittently), they found an additional problem w/ the right shift key linked to up arrow so they took it as it is under apple care ( thank goodness as it otherwise would have been out of warrantee). Receipt claimed $800 "flat fee" for parts (covered by warranty) and 100 for labor(also covered)?

I'll write back when it is returned....

P.s. They said it was a good thing I didn't try to remove keys to clean, I gave them crap for issuing keyboards that were not user maintainable unlike every other keyboard on the planet, that just made him uncomfortable....

Have you all done the new update? I know the new Update fixed a lot of problems with that. Also might want to try a can of air and try to blow out under the button. sounds like it is a keyboard problem many people are having. Keep eyes open for a recall.

I have the same issue as well. I got my b char typed double, but it is not always. Somehow if I try to focus on typing the sentence the b is not double. But when I just type as usual it will be keep in double.

Here I am trying to type:

bb b b b b b b b b b b bb b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b bb b b b b b b b b b b b b b b b b b

So as you can see the double b typed 3 times.

Did you get your system repair? Its a free repair!

由完成的

No, I think it will take a week or so to get it repaired. I am still using it for work.

Has anyone tried to repair it? How long it takes?

由完成的

Best to visit them ASAP so you get it noted, you don't want to loose out on the warranty coverage.

Even if you don't leave it that day they will be able to give you an idea how long. Different service centers have different times, so what I get may not be what you get.

I initially had issues with the B - sometimes not typing at all - and now it has moved on to the N key, which comes out in n double randomly, sometimes together withinn or at the end of the word, sometimes after a space.

Best solution is to sign this petition https://www.change.org/p/apple-apple-rec...

Apple will only do something about this when it starts to hurt the bottom line, which only happens when there is enough awareness of Apple's late quality problems.

Hi, I have the same problem with the letter b, id thought I would write a comment on my experience; I’ve been for a repair 4 times at the apple store. First time round they cleaned out the key; worked fine for 15mins when I got home. Then I had to go back, this time round they changed the top case including the touchbar; 48 hours letter the problem occurred; I went back they cleaned out the letter b key again. The problem occurred again when I got home. So now it’s back in for repair; they will replace the top case. Let’s hope this will work! I will let you guys know. I did go through the troubleshoot over a apple senior advisor; he mentioned it’s a software issue since he tested it out on the digital keyboard and the problem still persisted. But then again the people at the apple store said it’s a mechanical issue. So I have no idea...

I just brought my MacBook Pro with the same issue with the b key. Apple is aware of the issue and have create a quality program to replace with a redesign top case that addresses this issue. We’ll see if this is true in 5 days. This is my 4th time getting repaired. If it’s not fixed this time around I will be escalating for a complete replacement.

My Mbp was under AppleCare so no charge for me. You should contact Apple support to see if they will fix your top case since they developed a program specifically fixing this exact issue.
