If you are a Macbook Air user, there are a few ways to delete a user. The first way is to use the System Preferences application. In the System Preferences application, select the Users & Groups tab and then click on the Delete User button. The second way is to use the Finder. In the Finder, select the Users & Groups tab and then click on the Delete User button. The third way is to use Terminal. In Terminal, type sudo rm -rf user1user2
If you’re the only admin on a system, double-check to make sure you don’t mean to remove the sole admin account. You won’t be able to remove a solitary administrator account from a computer if it’s the only one; instead, you’ll need to either convert one of the other accounts into an administrator or establish a new admin user
On the bottom left, you’ll find Users & Groups. Select the padlock icon. Enter your password. On the left side, select Admin User and then Minus Sign Near Bottom. Choose one from the list and then Delete User after that.
Choose Apple menu System Preferences, then Users & Groups. Select the Add button below the list of users. Choose a type of user from the New Account pop-up menu. Give your new user a complete name.
From the Apple menu, choose System Preferences, then Accounts, Lock, and enter your password. Triple-check that all of the files for all of your old computer’s accounts have been copied to your new system.
In my case, it said a one-pass random erase would take 9 hours, and a one-pass zero-fill erase was estimated at about an hour. One step that should be included on this list is to delete the user’s account’s incomplete DMG backup file, which was generated as a result of the interrupted job.
