Forget a Wi-Fi Network on your MacBook Pro


Once a wi-fi network has been joined in OS X, the Mac will default to joining that network if it’s within range and available again. This is undeniably convenient for joining your home, work, and regular wireless networks, but it can be a nuisance when the Mac rejoins a network that you no longer want to connect to. While setting the wi-fi network priority is one option, another option is to have the Mac “forget” the network, preventing it from automatically rejoining again. This is particularly helpful if you live or work within an area that has open networks available that you do not accidentally want to join.
