A lovely aspect of any macOS is just how thought-out most of the processes are, without users having to even lift a finger. For example, once you connect to a WiFi network on your Mac, it will remember the network forever and automatically join it every time it becomes available.
When the WiFi is buggy and needs some work though, automatic connection might pose a problem. So learning how to forget networks on Mac might prove to be useful sooner or later.
How To Delete Network On Mac And Optimize WiFi
Your Mac’s ability to remember all past wireless connections, especially if you tend to travel regularly, will add up to quite a long scroll pretty quickly. Just imagine every new WiFi login at the airport, train station, hotel, restaurant, client’s office, open public network, and more. A good thing, at least, is that all WiFi credentials are stored in Apple Keychain, which then makes them available on your iPhone and iPad through iCloud. So why do you sometimes need to delete networks and how to do it?
