If you need to remove an administrator from your Mac without a password, there are a few different ways to go about it. The first option is to use the Recovery Mode interface. This can be accessed by pressing Command+R at the same time as you power on your Mac. Once in Recovery Mode, select “Utilities” and then “Terminal”. Type the following command and press Enter: sudo rm -rf /usr/local/bin This will delete all of the administrator-related files from your Mac. However, if you want to keep any of your user data or applications, you’ll need to create a new user account and copy over any files that you want to keep. Another option is to use the Terminal app on your computer and type the following command: sudo su - This will switch you into root mode on your Mac. From here, you can delete any administrator-related files by typing the following command: rm -rf /usr/local/bin However, this method is less secure because it allows anyone with access to your computer to delete administrator-related files without needing a password. The final option is to use Apple’s System Preferences tool. This can be accessed by clicking on “System Preferences” in the menu bar at the top of your screen and then selecting “Security & Privacy”. From here, you can click on “Users & Groups” and then click on “Administrator”. You’ll now be able to select which users or groups have administrative privileges on your Mac. ..
