Last Updated: August 18, 2021

This wikiHow will teach you how to use remove wireless networks from your preferred networks on a Mac. When your computer searches for wireless connections, it will show you all the available networks. Once you connect to a network (often with a password), it will appear in your preferred networks. In System Preferences, you'll be able to make these changes to your preferred networks. However, if you haven't connected to a network before, you can't remove it from the list of available networks. You can also remove a network to be able to connect to it using a different password.
