This guide shows you how to personalize your Mac's lock screen, adding a personal touch to your device's security. We'll cover changing the login screen image, wallpaper, and adding a custom message.

Personalizing Your Mac's Lock Screen

macOS offers customization options beyond the menu bar and Dock. You can personalize your lock screen with a custom message, user icon, and background image.

Changing Your Lock Screen Icon

To change the profile picture displayed on your lock screen:

1. Go to Apple menu > System Preferences > Users & Groups.
2. Unlock the lock (bottom left) using your password.
3. Select your user account.
4. Click your user icon to edit.
5. Choose a Memoji, emoji, monogram, photo from your camera, or an image from your Photo Library.
6. Click Save.

Use apps like Luminar Neo for quick image enhancements, including background removal and AI-powered enhancements.

Changing Your Lock Screen Wallpaper

To change your lock screen wallpaper:

1. Determine your Mac's screen resolution (Apple menu > About This Mac > Displays).
2. If necessary, resize your chosen image using Preview (right-click, Open With > Preview, Tools > Adjust Size) to match your screen resolution. Save the image as lockscreen.png.
3. Open Finder, Go > Go to Folder, and type /Library/Caches.
4. Drag your lockscreen.png into the Caches folder, replacing the existing file if prompted. If not prompted, locate the Desktop Pictures folder within Caches and replace the lockscreen.png there.

Note: Changing your desktop background will revert the lock screen to the default.

Use Wallpaper Wizard for high-quality desktop wallpapers.
