How to Remove a Network on a MacBook Keychain

By Mario Calhoun

The Keychain on your MacBook is a program that stores network keys and passwords for any website or wireless network on your computer and is considered the hub of password storage. When you first create an account on your MacBook computer, the Keychain application uses your account password to lock its information.
