How to delete a user account on Mac OS X

Macs with multiple user accounts sometimes need to delete a user account. Maybe you no longer need a specific user account, or you’re removing an old login, or just cleaning house, whatever the case, it is easy to remove a user from Mac OS X.

The method we’ll cover allows removal of any user account, whether it is an admin account or a standard account. Keep in mind that by deleting a user account, not only is the user account removed from the Mac which thereby prevents that user from logging into the Mac again, but in most situations that users files and data is also deleted as well. There are options to save the user Home folder data while still removing the user account login, however, or you can choose to completely and securely erase both the user account and the users Home folder.

How to Delete User Accounts from a Mac

The process of removing a user account is irreversible. Be sure to back up your Mac before deleting a user account or any user data.

    1. Go to the  Apple menu and choose “System Preferences”
    2. Select the “Users & Groups” preference panel

  1. You will be presented with three options when deleting the user account from the Mac, choose which is appropriate for your situation:
  • Delete user account but save the home folder to a disk image
  • Delete user account but keep the user home folder in /Users directory
  • Delete user account and delete the home folder (optionally, choose to erase home folder securely) – this completely removes the user account and that users files and apps from the Mac
  • Check the appropriate box and click on “Delete User” to completely delete the user account from Mac OS X

If you chose the option to completely remove the user account and the users Home folder, any and all files and apps in that users home directory will be deleted. If you choose one of the options to preserve the Home folder, it will be located in the /Users/ folder or the Deleted Users folder.

While deleting a user is permanent, you can always create a new user account on a Mac at anytime, though if the intention is simply to allow basic guest usage like internet access, then setting up the Guest User account on Mac OS X is often a better idea. Another option would be to hide a user if you don’t want it to be widely visible, which allows logins on that user ID but it won’t be visible in the obvious places throughout Mac OS X.
