I was running the latest firmware on an Apple 2007 Aluminum Wireless Keyboard, and MacBook Pro Keyboard, but the issue still persisted. However, oddly this fixed it:

1. Open System Preferences
   


2. Click Keyboard
   


3. Click Modifier Keys...
   


4. Select your keyboard from the Select keyboard: list.


5. Set the Caps Lock Key: to No Action.


6. Press OK.


7. Ensure your Caps Lock no longer works on your keyboard.


8. Click Modifier Keys... again.


9. Set the Caps Lock Key: to Caps Lock.


10. Press OK.

Now, the Caps Lock key works instantly for that keyboard. Repeat as-needed for each keyboard you own.

If you install Karabiner-Elements, it defaults to zeroing out macOS's obnoxious caps lock delay.

(edit: although just at this moment there's a bug to do with it in versions >= 12, so stick to <= 11.6)

https://pqrs.org/osx/karabiner/

This is the only solution I know of that both works on 10.12 and requires nothing more than installing & running an application without any special steps or reconfigurations.

1. Download and install the following software
   
   
   
   
   • Karabiner
   
   
   • Hammerspoon
   
   
   
   


2. Use Karabiner maps CapsLock key to F19.


3. Edit init.lua under the path ~/.hammerspoon, paste the code below.

pressedF19 = function()

end



releasedF19 = function()

    hs.hid.capslock.toggle()

end



f19 = hs.hotkey.bind({}, 'F19', pressedF19, releasedF19)

Then reload the hammerspoon config for changes to take effect.

Not really sure about this, but google found this. This was one of the suggestions, but it does not seem foolproof (or even close). There are more suggestions on the page.

1. Go to System Preferences > Keyboard & Mouse > Keyboard. Click on Modifier Keys. In the window that opens, for the Caps Lock key, select "No Action"


2. Install the "No CapsLock" script. Download at

In addition, if you hold down the key, even for a fraction of a second, it will go on automatically.

On Apple's discussion boards other's report that updating your keyboard's firmware can/will eliminate this delay.

It appears that the keyboard firmware update released today fixes this
issue.

Get keyboard firmware(s) from Apple.

Originally the answer by Martin Steven worked for me. This was when I used OSX 10.9.

After upgrading to OSX Yosemite (10.10) it stopped working. I found another, essentially the same, solution documented here

http://sleepycow.org/2014/07/removing-the-caps-lock-delay-on-a-macbook/

It uses updated version of the apps (with different names) that work with 10.10.

As requested - quoting the relevant sections from the link

1. Install Seil and Karabiner.


2. Go to System Preferences > Keyboard > Modifier Keys and change “Caps Lock” to “No Action.”


3. Using Seil, check “Change Caps Lock Key” and change the key code to 110. (Application Key)


4. Go to Karabiner, and in the search box, enter “application key to capslock.” Under For PC Users > Change PC Application Key, check off “Application Key to CapsLock.”

Just as an FYI, I found an alternative solution on Reddit:

1. Go to System Preferences -> Accessibility -> Keyboard
   


2. Check Enable Slow Keys
   


3. Click Options
   


4. Drag the Acceptance Delay slider all the way to the left


5. Press OK
   

However, this fix introduces a different problem: if you hold down a key to repeat it (such as delete) then the repeat delay is extremely slow.

Tested on macOS 10.14.4.
