How to Disable or Reassign the Caps Lock Key on a Mac

Disable caps lock in 3 easy steps!
1 minute

The caps lock key is one of the least used keys on a Mac. It's often a nuisance causing people to enter incorrect passwords when it's accidentally turned on by the graze of a finger. If you don't use the caps lock key and find it a bit of a nuisance, consider disabling or modifying the caps lock key by reassigning it to a different function.

By disabling the caps lock key, your caps lock key will have zero function or purpose. So, accidentally clicking the caps lock key will cause no issues. If you like using caps lock, this modification is not for you.

By modifying the caps lock key, your caps lock key will work, but not as a caps lock key. It will have an entirely different function based on what you decide to reassign it to. If you are currently struggling with an option key that is broken, this is a great workaround while you wait to get into the genius bar.

Note: these steps were done with macOS Big Sur, but should be relatively similar for most recent macOS versions.

Because your MacBook is so important for all that you do in a day, it is important to take good care of your Mac battery, monitor your Mac's battery health, and check the cycle count of your Mac's battery when to determine if your Mac needs a new battery. This might sound like a lot of maintenance, but checking your Mac's cycle count is an easy way to determine if your Mac needs a new battery, and it's actually incredibly simple. A battery's maximum cycle count is how many charge cycles your Mac can complete before the battery is no longer able to perform and will need replacing. In this guide, I show you how to check your Mac battery's cycle count and determine if your battery needs to be replaced.
