How to Delete a User Account in Mac OS X

Do you want to give your computer to another person so they can use it, but before you give it away you want to remove all of your data? If so, here’s an easy way to accomplish this. We’ll create a user account for the person who’ll be using the Mac, then we’ll delete your user account.

These instructions were written for OS X 10.5 and 10.6, but should work on previous versions as well though some of the names and wordings have changed subtly.

• Turn on the Mac and let it start up.
• Go to the Apple menu, select System Preferences and click on Accounts
• If the padlock in the lower left corner is locked then click on it to unlock it. Enter your user account’s password when prompted to do so.
• Click the plus sign button to add a new user account. Set “New Account” to “Administrator”. Enter the real world name of the new user of the Mac in the “Full Name” field. Enter a name in the “Account name” field; this name can not contain spaces, capital letters or punctuation marks. Enter a password in both the “Password” and “Verify” fields. Enter a password hint if you’d like.
• Click the “Create Account” button.
• Go to the Apple menu and select Log Out which appears at the bottom of the menu.
• You’ll be presented with a login window. Type in the account name and password for the account which you just created. You’ll be logged into this new user’s account and now that you’re no longer using your account it can be deleted.
• Go to the Apple menu, select System Preferences and click on Accounts
• If the padlock in the lower left corner is locked then click on it to unlock it. Enter your user account’s password when prompted to do so.
• Click on your user account which’ll be listed on the left-hand side of the window.
• Click the minus sign button to delete your user account.
• Select “Delete the home folder” to have all of the data in your user account deleted.
• Click the OK button. The actual deletion process could take 10-15 minutes, especially if there is a lot of data in your account.
• When the deletion process is complete you can close the System Preferences window.
