If you happen to be someone who does not use the Caps lock key too often, you might want to disable it completely on your Mac. That way you will also not accidentally hit it when you are typing a password on a website which is case sensitive in most cases. Here’s how to do that.
Disable Caps Lock on Your Mac
Click on the Apple logo in the top-left corner of your screen and select “System Preferences…”
Click on “Keyboard” on the following screen to access the keyboard settings for your Mac.
Click on “Modifier Keys…” on the screen that follows to modify what a key does on your machine.
On the screen that appears select “No Action” from the “Caps Lock Key” drop-down menu. What it does is tell your machine not to perform any action when the Caps lock key is pressed. It makes the key inactive on your machine. Click on “OK” when you are done to save the settings.
You can now press the Caps lock key on your keyboard and should notice that it does not work anymore. It just does not perform any action at all.
Conclusion
If you do not use the Caps lock key frequently on your keyboard, you can have it disabled using the above method. Image Credit: Caps lock
