Disable the Caps Lock Key on a Mac
Does anyone like the CAPS LOCK key? Yes, it can be useful for typing some things that happen to be all uppercase, but as many internet readers know, it can also be an obnoxious key that many Mac users accidentally press on their keyboards, leading to ALL THEIR LETTERS APPEARING UPPERCASE.
If you’re a Mac user who has become fed up with caps lock, either because you think it’s annoying or because you accidentally hit the key sometimes when typing, you’ll be pleased to discover that you can disable that key on any Mac keyboard completely, rendering it inoperable. This is done through an OS X systems setting, and requires no manual intervention with the keyboard itself, it’s all handled through a preference panel.
How to Disable the Mac Caps Lock Key
This will turn off the caps lock key completely, rendering presses on it as nonfunctional and lacking action. You can do this in all versions of Mac OS X, here’s what you’ll want to do:
- Open “System Preferences” from the Apple menu
- Click on “Keyboard”
- In the lower right corner, click on “Modifier Keys…”
- Click on the pull-down menu next to “Caps Lock Key” and select “No Action”
- Press “OK” and close out of System Preferences
That does it, no more caps lock. Now if you press the caps key, it won’t do anything – it is completely disabled. Try it out yourself with a text document open, where you can now press the key however many times and there won’t be anymore all uppercase typing as a result. If you do want to type all in uppercase, you’ll have to hold down the SHIFT key instead.
You’ll find that by using the same preference panel, you can also reassign the Caps Lock key to serve as one of the standard command keys, including Caps Lock, Control, Option, Command, or “No Action”, some of these alternatives may be desirable if you’d rather not have a useless keyboard button. For the time being, the ability to adjust this key is limited to OS X, while in iOS you can either just toggle the caps key on or off, but users are not able to disable it entirely or reassign the function.
Aside from the limited use of caps lock, why is it so hated? My theory is that because ALL CAPS is the universal internet indicator of yelling is why it’s viewed so poorly. Some others could argue that Caps Lock functionality has simply run it’s course, going from the most obnoxious key on the keyboard that seems to have an increasingly tiny place in the modern world of computing, to a place where it’s just not needed any longer, enough so that Google’s Chrome OS notebooks abandoned the key completely. We’ll see if Apple follows suit some day and also ditches the physical key, but for now you’ll just have to reassign the key or disable it as described above.
This works in all versions of OS X the same way, whether OS X Yosemite, OS X Mavericks, OS X Mountain Lion, or any other version, and it works with all keyboards too. Therefore, it doesn’t matter what OS or keyboard is being used on the Mac, it can disable the caps lock key if you wish to do so.
