Changing the picture in the background of your Mac's login screen won't change how well the device works. It's just a change to how your Mac looks when you log in. It won't change anything else. Some people would say that you have no reason to spend even a second of your time making such a useless change to your computer and that doing so would be a waste of time. We disagree with this assessment, and we think there are a lot of good reasons to change the background screen. Let's start by looking at how to modify/change your login screen in macOS (and change it back).
Before you can change the background when you log in to your Mac, you have to make sure that the picture is in the proper format and size. You can do that with most photo editing software, but the macOS Preview app works fine. Here's how to set up your login screen preview:
Once you've made your new login background picture, you must put it in the correct file on your Mac. You'll see it the next time you log in. Follow these steps to change the image that shows up in the background when you log in to your Mac.
Your login screen is different from your lock screen. When your Mac wakes up from its nap, you'll be able to see it. Your lock screen won't change until you change the background of your login screen. Change the background on your Mac's desktop to change the lock screen. Here's how to set your Mac's lock screen:
Several things come to mind when you think about why you might want to change the background of your login screen.
If you use your computer a lot, you'll see that background. Still, apps and other programs often take up most of your screen, so you might not see the background for long periods. But in the end, you will. Why not use a picture you like or that has some meaning for you? It might make using your Mac even easier than it is now.
You might want all of your employees to make the same impression on your customers. One way to do this is to put a standard background or company logo on the MacBooks they get from work. It eliminates the chance that an employee will use an inappropriate background and gives the computers of your support team a unique look when they start up.
People who don't know how to use public computers, like those in a library, can see instructions in the background of the login screen. This can help people who have never used the machine before and reduce the number of requests for help.
