Single keypress types repeated characters (MacBook Pro 2016 & 2017)

Solution 1:

Finally, if anyone had or has the same issue, Apple is replacing the keyboard free of charge / refunding the past repair : https://www.apple.com/support/keyboard-service-program-for-macbook-and-macbook-pro/

UPDATE. There is a small program, called Unshaky written on Swift. It fixed this issue for me. It lets you configure a timeout for each key to suppress duplicate keypresses. For instance, if the 'e' key is giving you trouble, you can configure the timeout for a longer duration and adjust for the best results. There is also a statistics panel that shows how many times a key was suppressed by the software, as well as a detailed breakdown for each key.

I have the same problem. I gradually started noticing double key presses for few keys showing up in the text I typed. The offending keys are: i, t and e.

How to reproduce

• I went to Keyboard > Key Repeat > Off.
• When I press down the i and then slide my finger from the left edge to the right edge of the key, it triggers more keypresses.
• If I key my finger still and press down with more pressure, it sometimes triggers more keypresses.

Pressure seems to be important. If I rub lightly it doesn't happen as much.

I wonder what is causing it. I hope its dust. I will clean my keyboard tonight. But seeing as they all occur in the same row, maybe its something to do with the circuitry - I have to research more about how the keyboard works.

Sprayed my laptop keyboard with a lot of pressurized air. Did not help at all. the T and I keys are still consistently causing issues.

The current range of MacBook Pros seem to be suffering from this problem with the keyboard. To the point where they have released this technical note about how to attempt a fix.

But a recent article has brought this to the forefront of the tech-news, and as a result Apple may be forced to take more action on this obvious design flaw. It has reached the point where there is even a song now.

I also had a problem with the L key on a new laptop at work. Spare a thought for those of us who live in a country that has no Apple stores. From here in Thailand, any repair that requires a return means a three-week (at least) trip to Singapore. It's still under repair, and we are still waiting for it to come back.

Solution 4:

A seemingly workable way is to Enable Slow keys under the Accessibility setting of Keyboard. For me, a slight adjusting above Short can mostly resolve the problem.
