CapsLockNoDelay

Removes annoying delay when pressing the caps lock on Mac OS.

Confirmed working on MacOS Sequoia 15.5

Built-in Alternative

Turns out there is a built-in alternative for deactivating the CapsLockDelay. Thanks @decodism for pointing that out!

hidutil property --set '{"CapsLockDelayOverride":0}'

Just run this, no other steps are needed.

If that doesn't work, continue with the regular installation.

Install

Manual

Download from releases or compile from source.

Copy CapsLockNoDelay.app to /Applications folder.

Homebrew

To install it using Homebrew, open the Terminal app and type:

brew install --cask capslocknodelay

Usage

Go to System Preferences -> General -> Login Items, add CapsLockNoDelay.app to the list.

Go to System Preferences -> Security & Privacy -> Privacy -> Accessability -> Check CapsLockNoDelay.app -> Input Monitoring -> Check CapsLockNoDelay.app (if present).

You won't see any settings / GUI, the app is running in the background (you can see it in Activity Monitor).
