It is a convenient option to create a guest account for other users to access your computer while unattended. If the user no longer needs access, you can potentially leave your business and personal files at risk if you have accidentally given read and write permissions to access certain areas. The safest way to avoid this is to remove unnecessary accounts using the ‘Users and Groups’ section that is located in System Preferences.

Follow these steps to remove your guest account.

1. Click the “Apple” icon on the menu bar in the upper left corner.

2. Select “System Preferences“.


3. Click the “Users & Groups” icon.

4. Click the “Lock” icon and then enter your administrator name and password as prompted. This unlocks the settings to allow you to make changes to this section.


5. Select the account on the left column. In this case, it will be the “Guest User” account. Deselect the “Allow Guests to Log in to This Computer” option. The Guest User account is disabled.


6. Click the “Lock” icon to prevent others from changing the settings in this section.
