About Administrator Accounts
An administrator account has the same basic capabilities as a standard user account, including its own Home folder, desktop, backgrounds, preferences, Music, bookmarks, Messages accounts, Address Book/Contacts, and other account features. Setting an administrator account apart is its elevated privilege levels. Administrators can change system preferences that control how the Mac works and feels, install software, and perform many special tasks that standard user accounts cannot perform. Your Mac computer needs only one administrator account, but allowing one or two other trusted people to have administrative privileges is a straightforward process.
Creating a New Administrator Account
You’ll need to be logged in as an administrator to create or edit user accounts. You created an administrator account when you first set up your Mac. Then: A new Home folder will be created, using the account’s short name and a randomly chosen icon to represent the user. You can change the user icon at any time by clicking the icon and selecting a new one from the dropdown list of images. Repeat the above process to create additional administrator user accounts. When you’ve finished creating accounts, click the lock icon in the bottom left corner of the Users & Groups pane to prevent others from making changes.
Promote an Existing Standard User to Administrator
You also can promote a standard user account to an administrator account. Open Users & Groups as above, log in to your Administrator account, and select the account you wish to change. Place a checkmark next to Allow user to administer this computer.
