One of the main reasons to lock your MacBook is to protect the device from other people who might want to access the Mac while you are away.
Another reason for MacBook users to lock their devices is to avoid unwanted input. For instance, when you are cleaning the keyboard, you want the keys to be unresponsive so you avoid potential accidents.
Deleting files accidentally because you do not know keyboard shortcuts (something that happened to me recently when I was trying to remove crumbs from my keyboard in a hurry) is a problem. Another example is realizing how to shutdown Mac with keyboard shortcuts without wanting to shut down the computer.
If you are unaware of how to lock and unlock the Mac keyboard on your computer, fret not. It is relatively simple, and you will find the answers in this article.

How to Enable Num Lock on Your Mac’s Keyboard

Troubleshooting MacBook Keyboard Issues
#1 – Clean Your Keyboard
When it comes to cleaning your MacBook’s keyboard, there are a few different approaches you can take. You can use a can of compressed air to blow the dirt and dust out of the keys, or you can use a damp cloth to wipe down the keys. If you’re dealing with more than just a little bit of grime, you may need to resort to using a mild cleaning solution and a toothbrush to scrub the keys clean.
Once you’ve got the keyboard clean, it’s important to protect it from future dirt and grime build-up. One way to do this is to invest in a keyboard cover. Keyboard covers come in a variety of materials, including silicone and plastic, and they help keep your keys clean while also providing a bit of extra grip.
If you don’t want to use a keyboard cover, another option is to simply avoid eating or drinking near your MacBook. Crumbs and spills can quickly turn into a sticky mess, so it’s best to play it safe and keep food and drinks away from your computer.
#2 – Disable Slow Keys
If you have ever accidentally hit the Caps Lock key and found yourself unable to type properly, you know how annoying it can be. Thankfully, there is a way to disable Slow Keys on a MacBook. This will prevent the Caps Lock key from being activated inadvertently and will make typing much easier.
To disable Slow Keys:
- Open System Preferences and click on Accessibility.
- Scroll down to the Interacting section and click on Keyboard.
- Under Key Repeat, select “Off”. This will disable the Caps Lock key from being activated inadvertently.
#3 – Disable Mouse Keys
Mouse Keys allow you to control the mouse pointer using the keyboard. While this can be a useful feature for some users, it can also be a nuisance if you accidentally enable it.
- Open System Preferences.
- Click on Accessibility.
- Scroll down to the bottom of the list and click on Mouse & Trackpad.
- Under the Pointing & Clicking section, make sure that the box next to Enable Mouse Keys is unchecked.
