Dear Mac enthusiasts,
how to forget a network on mac! To forget a Wi-Fi network on a Mac, open the Wi-Fi menu from the menu bar and select the network you want to forget. Then, hold down the Option key and click the network name. You'll see a pop-up menu with the option to forget the network. Click it and the network will be removed from your list of available networks. If the network still appears, try resetting your network settings. Go to System Preferences > Network > Advanced > Reset. This will reset all your network settings and the stubborn network should be gone. I hope this helps!
