wifi iconIf you take your Mac everywhere with you, there's a good chance that it has connected to a number of private and public Wi-Fi networks over that time.

These networks are remembered by macOS so that in the event that your Mac encounters one of them again, it can connect to it automatically and you won't have to manually select it or enter the password.

If you want, you can edit this list of "preferred networks" that your Mac keeps and change individual network connection settings. Whether you want to remove redundant networks or just forget a specific one, the following steps guide you through the process.
