Understanding Mac Administrator Accounts and Their Purpose
Your Mac computer uses different types of user accounts to organize how people can work with the system. An administrator account is one of these types, and it has special powers compared to other accounts. The administrator account can install software, change system settings, create new user accounts, and modify security features. If you're the main user of your Mac or you share it with others, you may need to know who has administrator rights on the machine.

When someone sets up a Mac for the first time, they typically create an administrator account without thinking much about it. This first account automatically gets administrator privileges. Over time, as people add new users to their Mac or change settings, the original administrator account holder may no longer be involved with the computer. This creates a situation where someone might inherit a Mac or work on a shared machine without knowing who the administrator is.
There are practical reasons to identify your administrator username. When you try to install a program, change your network settings, or update macOS, the system often asks you to enter an administrator password. Without knowing which account has these permissions, you might waste time trying to use the wrong password. Additionally, if you're troubleshooting problems or trying to reset something on your Mac, knowing the administrator account helps you understand what options are available to you.
Mac computers running modern versions of macOS—from Big Sur through the current Monterey and newer versions—all use the same basic account structure. Whether you have an Intel Mac or an Apple Silicon Mac (like the M1, M2, or M3 models), the process of finding your administrator username is similar. The information in this guide works across different Mac models and recent operating system versions.
Practical Takeaway: Before you start looking for your administrator username, think about whether you need it for a specific task. Knowing the administrator account name helps you understand who can make changes to your Mac and prepares you for situations where the system requests administrator credentials.
Checking Your Own Account Status in System Settings
The most direct way to learn whether your current account has administrator privileges is to look at your account settings. Apple built a straightforward tool into macOS that shows you exactly what type of account you're using. This method takes only a few minutes and doesn't require you to remember passwords or navigate complex menus.

Start by clicking the Apple menu in the top-left corner of your screen. This opens a dropdown menu with several options. Look for and click "System Settings" or "System Preferences" depending on your macOS version. Older Macs use the term "System Preferences," while newer versions starting with Monterey and later use "System Settings." Both lead to the same kinds of controls.
Once System Settings or System Preferences opens, look on the left sidebar for an option related to user accounts. On newer Macs, this might be labeled "General" followed by other options, or you might see "Users & Groups" directly. Click on the appropriate option. The system may ask you to authenticate—this means entering your password to prove you have permission to view account information.
After you've navigated to the account settings area, look for a list of user accounts on your Mac. Your current account should have a label next to it. If it says "Admin" or shows an administrator icon (usually represented by a small gear or person symbol), then your account has administrator privileges. If it says "Standard" or "User," then your account is a regular user account without administrator powers.
If you see that your account is a Standard User, this means someone else on your Mac has the administrator account. You'll need to ask that person when you need to make system changes, or you can use one of the other methods in this guide to identify who holds the administrator account.
Practical Takeaway: Checking your own account type through System Settings is the quickest way to learn whether you personally have administrator rights. Write down whether you're an Admin or Standard User—this information helps you understand what actions you can take on your Mac without asking someone else for their password.
Finding Administrator Names Through System Preferences Account Lists
If your account is a Standard User account, or if you need to identify all administrator accounts on your Mac, the Users & Groups section in System Settings provides a complete list. This method shows you every person who has an account on your computer and what type of account each person has. On a personal Mac, this is usually just one or two accounts, but shared family computers or work machines might have more.

Open System Settings or System Preferences as described in the previous section. Navigate to the Users & Groups area and click the lock icon at the bottom of the window if it's locked. You'll need to enter your password or use your fingerprint (if your Mac has Touch ID) to unlock these settings. This security measure prevents people from changing sensitive account information without permission.
After unlocking, you'll see a list of all user accounts on your Mac. Each account shows a name and a small picture or icon. Below or next to each account name, you should see text indicating what type of account it is. Look specifically for accounts labeled "Admin" or showing an administrator badge. These are your administrator accounts.
The account names you see here are the usernames you need to know. They might look different from the display names. For example, someone might have "Michael Chen" as their display name but "mchen" as their username. When the system asks for an administrator username, you need to use the actual username, not the display name. Write down the exact spelling and capitalization of the administrator username you find.
On some Macs, particularly older ones or those shared within families, you might find multiple administrator accounts. This is common in households where both parents have administrator access, or in offices where several people need system-level permissions. Each administrator account is equally powerful, so any of them can perform administrative tasks.
Practical Takeaway: The Users & Groups section gives you a complete picture of who has administrator access on your Mac. Write down all administrator usernames (not display names) in a safe place so you have this information when you need it for installing software or changing settings.
Using Terminal Commands to Identify Administrator Accounts
For people who are comfortable using Terminal—the command-line tool built into every Mac—there's a more technical way to find administrator information. Terminal is a program that lets you type commands directly to your Mac's operating system. While this method sounds complicated, the actual commands are short and straightforward. This approach is useful if the graphical methods aren't working or if you want to double-check what you found through System Settings.

Open Terminal by going to Applications, then Utilities, then double-clicking Terminal. You'll see a black or white window with a command prompt (a line of text ending with a dollar sign or percent sign). This is where you type commands. Type the following command exactly as written: dscl . list /Users UniqueID and then press Enter. This command asks your Mac to show you a list of all user accounts and their unique identification numbers.
The system will show you a list of account names. Most of these are system accounts that run behind the scenes and aren't for human use—they'll have names like "nobody," "root," or "daemon." Human user accounts are usually the ones with regular names or usernames. If you want to check whether a specific account has administrator rights, type this command: dseditgroup -o checkmember -m username admin Replace "username" with the actual account name. If the account is an administrator, the system will tell you "yes is a member of the admin group."
Another useful Terminal command shows you more detailed information about all accounts: dscl . list /Users | grep -v '^_' This filters out the system accounts and shows primarily human user accounts. Learning these commands helps you understand your Mac's account structure more deeply and gives you information that might not be visible in the graphical settings.
If you're nervous about using Terminal, remember that just looking at information and reading output won't hurt your Mac. Only commands that change settings can cause problems. Reading commands are safe, so you can experiment without worry. If you make a mistake typing a command, just press Enter and try again—the worst that happens is you get an error message.
Practical Takeaway: Terminal commands give you direct access to account information and work even if the graphical interface has problems. Write down the administrator usernames you find, and keep this Terminal knowledge in mind for future situations where you need detailed technical information about your Mac.
