On my MacPro there is one issue (and guys from Apple think this is feature...) that annoys me very much: there is a time delay between CapsLock switching. I used to do that fast. If I go to preferences and reassign caps lock to any other button and then back it works OK then, so it is not a hardware problem.

Is there any way to fix that ?

    Wow that is an insanely great feature - and I never even noticed I had it! That explains why I never ever make that "oops - hit cAPS LOCK" mistake when typing quickly! I guess this feeling of enlightenment is the same as what some Mac users feel once they realize that the Force Touch trackpad actually clicks back at you (youtube.com/watch?v=x3B3bHt8ya8)

    I don't understand people like "conny". I know they must exist as Apple's claimed reason for this "feature" is that it reduced the number of accidentally-activated caps lock. But HOW does someone ACCIDENTALLY hit caps lock? I type literally 145 wpm (tested on typeracer) and have literally never in my life encountered this problem. The A is right under your pinky and isn't a moving target. There should be no way to accidentally hit caps lock. This "feature" is catered towards the bottom end of the population who doesn't know how to type, and alienates those of us who actually CAN type.

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.

    this doesn't work on high sierra 10.13.4. if you disable the caps lock on a usb keyboard and put it back on, it still has the delay.

    ok, the only solution that for me (using a cheap ISO keyboard): github.com/tekezo/Karabiner-Elements/issues/1423 Install Kabariner Elements 11.6.0 where intially the CapsLock delay is set 0. Works great and there's no more headache about this ridiculous "feature".

Just as an FYI, I found an alternative solution in another question:

  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 other problems, including:

  • If you hold down a key to repeat it (such as delete), then the repeat delay is extremely slow
  • Some keyboard shortcuts like Crtl+Shift+Tab may no longer work

Tested on macOS 10.14.4 and 10.15.7

  • Incredible... this worked even better than the suggestion at the top. (They both improve it for some whacky reason)

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

The version you need to install depends on your macOS version.

macOS 10.15.6 and above

Download and install Karabiner-Elements 13.3.0 or higher.

macOS 10.11 through 10.15.5

Download and install Karabiner-Elements 11.6.0.

(Note that Karabiner-Elements 12.0.0 - 13.1.0 re-added the Caps Lock delay, and 13.3.0 isn't available on older OS versions.)

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.

    Thank you, worked a charm. I had tried 3 different Dell keyboards, and just thought the caps lock on all Dell keyboards was rubbish, until I noticed them working fine on a Windows PC. This is just the usual presumptuous idealistic crap that Apple does all the time, trying to solve problems that don't exist, and creating problems in the process.

    @TomWardrop agreed (& doubly so, as the Karabiner guys had to apparently do something of a rewrite just to get things to happen with newer versions of the OS) Aug 24, 2017 at 3:38

    @JanKyuPeblik I agree perfectly, that the caps lock delay is a non-feature ("bug") solving a problem that wasn't one. But rewriting a core API is something that should happen from time to time, because no OS should stay 1980 forever, so there is no way around rewriting things from time to time. Albeit of course things should get better with a new API and not worse.

    Looks like the problem is fixed perfectly in Karabiner-Elements v13.3.0. I've tested and confirmed that there is no delay, the Caps Lock light still works, and it still works on the lock screen without getting stuck. Can you update your answer for this? Thanks to Matias Simone for spotting this.

If you want a simpler solution than Karabiner, I've written a very small, open source tool to fix exactly that.


  • Thanks so much for building this! I just tried it out, and I'm not sure if it's starting up properly. I followed the steps in your readme file and also got past the Mac trying to stop me from opening it because it couldn't scan it or something. But when I go to Activity Monitor, then I can't see it running when I look for a process starting with "Caps". I'm also still getting the caps lock delay. Is there somewhere I can look at logs for the app? Or I wonder if something on my Mac is blocking it from starting?

    After checking my system log, it looks like the process was exiting with code 1. I checked your code and can see it also needs accessibility permission, so I went and manually added it to the Security/Accessibility list and granted access, and now it's working. After doing my test (which is just repeatedly pressing a then Caps Lock and repeating), it looks like it's fairly reliable but occasionally hiccups and doesn't work as expected. I'll keep using it and see how I go!

  • I've noticed that each time I turn Caps Lock on, then the Caps Lock light on my USB keyboard comes on, then turns off for a split second, then comes back on. I wonder if something else on the OS is fighting with your app? Or maybe the app is accidentally toggling it twice?

  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()

hs.hotkey.bind({}, 'F19', pressedF19, nil)

Then reload the hammerspoon config for changes to take effect.

  • I ended up moving hs.hid.capslock.toggle() into pressedF19 since this is more consistent with the default behaviour and is also how it works on Windows.

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 http://home2.btconnect.com/Taniwha/ (look near bottom of page)

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

    Holding down for a fraction of a second is exactly what people are complaining about. It's really stupid. Imagine you had to hold down the "E" key for a fraction of a second to really indicate you actually wanted to type it. "Oh it's to prevent users from ACCIDENTALLY hitting the key". Bullshit; I type 145 wpm as measured on typeracer and have literally never in my life ACCIDENTALLY hit caps lock. OTOH my time is wasted typing constants and doing a double take thinking it was MY FAULT for missing the caps lock key, when actually it was Apple gaslighting me with their delay "feature".

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

Re: Delay problem with caps-lock

Apr 8, 2008 3:52 PM

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

Get keyboard firmware(s) from Apple.

  • Any solution for Macbook Air keyboards on Windows? Feb 21, 2013 at 22:00

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


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.”

I had exactly the same problem, I could solve it by installing Karabiner-Elements and making the following modification :

  • select the Simple Modifications tab
  • add a new modification (Add Item)
  • and put from key caps_lock to key caps_lock

enter image description here

  • Nice find! Looks like Karabiner-Elements v13.3.0 fixes the problem out-of-the-box. Note that the remapping in your answer isn't actually needed; it still works without it.
    – Sam
    Mar 2, 2021 at 3:24

If you don't want to install Karabiner just for that, you can use brew install --cask capslocknodelay, it's nice lightweight and open-source tool GitHub.

Do not forget to enable it in the settings:

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

  2. System Preferences -> Security & Privacy -> Privacy -> Accessability -> Enable CapsLockNoDelay.app

  3. System Preferences -> Security & Privacy -> Input Monitoring -> Enable CapsLockNoDelay.app (if present).


This happened on my new MacBook Air, I contacted Apple Support and these were the instructions that were given to me and WORKED:

Go to System Preferences > click Accessibility > click Keyboard > then click Hardware > Select Enable Slow Keys > then click Options > Drag the Acceptance Delay slider to set how long you want your Mac to wait before it responds after the key is pressed.

I hope this helps :)
