Customizing the lock screen of your Mac is a fun and easy way to enhance your user experience. In addition to protecting your data, the screen can help you find your way into your Mac easily. There are several ways to customize the Lock Screen, from changing the profile picture to choosing a cool message.
The most obvious option is to choose a new background or icon. You can use an image from another folder or download an image from the Internet. Be careful with high-resolution images, though, because this can slow your Mac down. Instead, choose a picture that is slightly larger than your screen.

Another snazzy option is to set an inspirational quote as your lock screen message. This might be something like, “I’m glad I’m here,” or, “You are important,” or, “I am a creative person.” But whatever you decide, it’s a nice way to make a positive first impression.
If you’re looking for a more subtle approach, consider using the preview app to change your Mac’s lock screen image. It can be found in the Applications folder or by typing in Command + S. Once you’re in the app, you’ll see a set of options including “Adjust Size” and “File.” Choose one of these two and then hit the “OK” button.
You can also use the Wallpaper Wizard to add a cool touch to your Lock Screen. You can either choose from the various types of backgrounds available, or you can create your own. After you choose a design, you can use the preview to see how the wallpaper will appear in a lock screen. A preview is a small window that appears on your screen, and is a great way to test out your choice before you commit to it.
You can even change the lock screen message itself. This is the best way to display a personalized message, such as, “I’m here to watch you!” or, “I’m here to help you get your work done,” or, “I’m here to do what it takes to be the best at what you do.”

Other ways to customize the Lock Screen include adding a new one or making a few tweaks to an existing one. By default, Macs link the desktop and lock screens, but you can change this so you’re always logging into the correct one. Also, you can disable alerts for individual apps.
Lastly, you can link your Focus mode to the lock screen. Specifically, you can link “After Sleep or Screen Saver Begins” to your lock screen. While this may not be the most obvious option, it does allow you to easily toggle between Lock Screens and Focus modes.
Changing the lock screen isn’t a complicated process, and you can find all the information you need in one place. To change your Mac’s lock screen, simply follow these easy steps. Whether you’re changing your profile picture, your favorite inspirational quote, or changing the lock screen message itself, it’s a fun and easy way to customize your Mac.
