> How do you know if you are running as root user or standard user?
Open System Preferences, then User Accounts, then find your user name in the list of accounts. It should tell you if your account is Admin or Standard. If it’s Standard then you are not root, and can’t be even if you try.
If it’s Admin, then you can become root if you request it. To tell if you are root, open Terminal (in Applications, Utilities) and type the command:
whoami
Then the Return key. It will print your username.
Thanks
