Changing the Lock Screen Icon on Mac

Are you tired of looking at the same old lock screen icon on your Mac? Well, you’re in luck!

In this tutorial, we’ll show you how to change the lock screen icon on your Mac to something more exciting and personal. With just a few simple steps, you can customize your lock screen and make it truly yours.

Step 1: Find the Icon You Want

The first step is to find the perfect icon that you want to use for your lock screen. This could be an image or an icon file that you have saved on your computer or downloaded from the internet. Make sure it’s a high-quality image so that it looks great when displayed as your lock screen icon.

Step 2: Convert the Icon to PNG Format

Before we can use the icon as our lock screen image, we need to convert it to PNG format. PNG is a widely supported image format that works well for this purpose.

There are many online tools available that can help you convert your image to PNG format. Simply upload your image and download it in PNG format.

Step 3: Rename and Resize the Icon

Once you have your icon in PNG format, rename it to “lockscreen.png” or any other name of your choice. This will make it easier for us to locate and use the file later.

Additionally, ensure that the dimensions of the icon are suitable for a lock screen display. A square-shaped image with dimensions around 200×200 pixels usually works well.

Step 4: Access Terminal

To change the lock screen icon, we need to use Terminal – a powerful command-line interface tool available on Mac. To open Terminal, go to Applications > Utilities > Terminal or simply search for “Terminal” using Spotlight.

Step 5: Enter the Terminal Command

Once you have Terminal open, enter the following command:

sudo cp /path/to/lockscreen.png /Library/Caches/

In the above command, replace “/path/to/lockscreen.png” with the actual path to your lock screen icon file that you renamed in Step 3. For example, if your icon file is located on the desktop, the command would be:

sudo cp ~/Desktop/lockscreen.png


The “sudo” command is used to run a command as a superuser or administrator. You may be prompted to enter your password when running this command.

Step 6: Log Out and Check Your New Lock Screen Icon

Now that you’ve entered the Terminal command, it’s time to log out of your Mac account. Go to the Apple menu and select “Log Out [Your Username].” Once you’re logged out, you’ll see your new lock screen icon displayed on the login screen.

If you’re using FileVault disk encryption on your Mac, you may need to restart your computer for the new lock screen icon to take effect.

  • If you want to revert back to the default lock screen icon, simply delete or rename the “com.png” file located in “/Library/Caches/” and restart your Mac.
  • You can change your lock screen icon as often as you like by following these steps again with a new image.

Congratulations! You’ve successfully changed the lock screen icon on your Mac.

Now every time you log in or wake up your Mac, you’ll be greeted by your customized lock screen icon. Enjoy the new personalized touch on your Mac!
