This method ensures your MacBook will not automatically connect to that network in the future.

Begin by clicking the Apple menu and selecting System Preferences, then navigate to Network. In the Network pane, select Wi-Fi from the list on the left side. Next, click the Advanced button located in the lower right corner of the window. Here you will find a list titled Preferred Networks, which contains all the Wi-Fi networks your MacBook has connected to and saved.

To forget a network, simply:

  • Locate the network you want to remove from the list.
  • Click on it to highlight.
  • Press the minus (-) button below the list to delete it.
  • Confirm your choice if prompted.
  • Click OK to close the dialog.
  • Finally, click Apply to save the changes.

This process removes the network from your preferred list, preventing automatic reconnection and clearing any saved passwords associated with that network.

Using the Terminal to Forget a Network

For users comfortable with command-line interfaces, the Terminal provides an alternative method to forget Wi-Fi networks. This approach is particularly useful for scripting or managing networks remotely.

To begin, open Terminal from the Utilities folder or via Spotlight search. Use the following command to list all saved Wi-Fi networks:

“`bash
networksetup -listpreferredwirelessnetworks en0
“`

Here, `en0` typically refers to the primary Wi-Fi interface on most MacBooks. If your MacBook uses a different interface, replace `en0` accordingly.

Once you identify the network you want to forget, use the following command to remove it:

“`bash
networksetup -removepreferredwirelessnetwork en0 “NetworkName”
“`

Replace `”NetworkName”` with the exact name of the Wi-Fi network you wish to delete. It is important to include the quotation marks if the network name contains spaces.

After executing the command, the specified network will be removed from your list of preferred networks, and your MacBook will not attempt to connect to it automatically in the future.
