When you first start your brand new Mac, you have to setup a new user account. This user account is the administrator account using which you can make system wide changes and create new user accounts. If you are the only user on your Mac then you do not really more than one user account.
But if you share your Mac with others than you would need many other accounts for other people such as your family members or coworkers. Mac OS X Mojave and Catalina also allow creation of user accounts with parental controls which are great for the kids in a family.
Different users can identify their user accounts by the pictures that are associated with them. You can change the user account pictures to the actual photographs of those users to make them much more personalized. This picture is displayed at the logon screen when you start your Mac.
Here is how you can change the picture for your local user account on Mac:
- Click on the Apple icon and select System Preferences from the menu that appears.
- In the System Preferences window, click on the Users & Groups.
- In the Users & Groups window, select the user account that you want to customize, click on the lock icon, enter your administrator account credentials, and then click the picture for that user account.
- In the next window, you can choose one of the stock pictures or select a picture from the local storage drive.
- Click on the Save button and finally click on the lock icon once again in order to prevent any changes. And finally close all the windows opened in the above steps.
There are dozens of beautiful user account pictures available in your Mac but if you really want to personalize your Mac, then you should use your own photograph instead of the stock images. In case of the computers used for a business, a logo for the business could serve as the user account.
