How To Change Picture On Login Page On Mac


Changing the picture on the login page of my Mac has always been one of those small personalization touches that make the whole user experience feel more tailored to my taste. It’s a simple and fun way to add a touch of uniqueness to my login screen, and I’m here to guide you through the process.

Step 1: Choose the Perfect Picture

The first step is to find the picture you want to use as your login page background. It can be anything that speaks to you – a photo of your loved ones, a breathtaking landscape, or even a cool abstract artwork. Just make sure it’s an image that you’ll enjoy seeing every time you log in to your Mac.

Step 2: Prepare the Picture

Before we can set our chosen picture as the login page background, we need to make some adjustments to ensure it fits perfectly. Start by resizing the image to the correct resolution for your Mac’s screen. You can do this using image editing software like Photoshop or even the Preview app that comes with macOS. The optimal resolution for the login background image is the same as your screen resolution.

Additionally, you may want to tweak the brightness, contrast, or any other aspect of the picture to make it visually pleasing when displayed as your login page background. Take your time to experiment and find the perfect settings that complement your image.

Step 3: Replace the Login Page Picture

Now that your picture is ready, it’s time to replace the default login page picture. Here’s how:

  1. Open Finder and navigate to the Applications folder.
  2. Locate the “Utilities” folder inside Applications and open it.
  3. Inside the Utilities folder, find and open the “Terminal” application.
  4. In the Terminal window, type the following command and press Enter: sudo nano /Library/Caches/
  5. You will be prompted to enter your administrator password. Once you do, press Enter.
  6. A text editor will open, showing the path to the login page picture. Delete the existing path and replace it with the path to your own picture. If your picture is located in the Pictures folder, the path would look like this: /Users/yourusername/Pictures/yourpicture.jpg
  7. After updating the path, press Control + O to save the changes and then Control + X to exit the text editor.

Step 4: Restart and Enjoy

Now that you’ve replaced the default login page picture, it’s time to see the magic in action. Restart your Mac, and when the login screen appears, you’ll be greeted by your chosen picture as the background. Enjoy the personal touch every time you log in!


Changing the picture on the login page of your Mac is a simple yet rewarding way to personalize your user experience. By following these steps, you can choose a picture that resonates with you and replace the default login page background. Remember to have fun and experiment with different images until you find the perfect one. Enjoy logging in to your Mac with a personal touch!
