Unshaky

It seems on macOS 10.15.6, Unshaky no longer works unless by default, workaround: issue #166

Unshaky tries to address an issue on the butterfly keyboard (Macbook, Macbook Air 2018 & MacBook Pro 2016 and later): Double Key Press (See "User complaints" below).

Apple made it difficult to replace only the keyboard and it costs hundreds of dollars. Unshaky might save your keyboard by dismissing such "second key hits" (any key presses that occur no later than x milliseconds after the previous effective one). I fixed my "w" key with Unshaky, and if it does not work for you, open an issue here. The image below illustrates how Unshaky works.

[June 2018] Good news, Apple launched a Keyboard Service Program for MacBook and MacBook Pro, and go get your keyboard fixed, maybe temporarily.

[May 2019] Apple extends the service program to cover all MacBook (Air & Pro) with 3rd gen butterfly keyboards.

[May 2020] The Verge: The saga of Apple’s bad butterfly MacBook keyboards is finally over.

How-To

Download Unshaky.app here

First, move the "Unshaky.app" to your "/Applications" folder.

Grant Accessibility Permission

Why "Input Monitoring" is not enough in Catalina?

Follow the instruction when you first open Unshaky. If the instruction does not work for you, go to System Preferences -> Security & Privacy -> Privacy (Tab) -> Accessibility (Left panel) and add "Unshaky.app." Make sure it is checked.

Since macOS 10.15.6, also add Unshaky to Privacy (Tab) -> Input Monitoring (Left panel), see issue #166

Launch at Startup (Optional)

Go to System Preferences -> Users & Groups -> Login Items (Tab) and add "Unshaky.app".

Configure delays for your defective keys

Click Unshaky icon in the menu bar and select "Configure" to configure delays for the defective keys.

How to pick an appropriate delay?

I don't think there is a universal delay value for all people. If you type very fast, you might want to have a shorter delay. I use 40 ms since I am a fast typer. With a long delay, I cannot type "apple" because the second "p" is likely to be blocked. Some users found 60 ms a sweet spot and some have no issue with 80 ms. My suggestion is to start with a short delay (like 40 ms) and gradually increase it.
