Begin by clicking the Apple menu in the top-left corner of your screen, then select System Preferences. From there, navigate to the Network panel. In the sidebar, select Wi-Fi, and then click the Advanced button at the bottom right of the window. This will open a list of all the WiFi networks your MacBook has connected to in the past.

Within this list, you can select the network(s) you wish to forget. Use the minus (-) button below the list to remove the selected network(s). After making your changes, click OK, and then Apply to confirm the modifications.

Key points to remember during this process:

  • Removing a network deletes saved passwords and settings.
  • Your Mac will no longer connect automatically to that network.
  • You can always rejoin the network later by selecting it from available networks and entering credentials anew.

Managing Preferred Networks and Connection Order

The order of networks in the saved list determines the priority your MacBook gives when multiple known networks are available. By adjusting this priority, you can control which network your Mac connects to first.

To reorder networks, simply drag and drop networks within the saved list in the Advanced network settings window. Placing a network higher on the list increases its connection priority.

Consider these best practices for managing preferred networks:

  • Prioritize trusted and secure networks at the top.
  • Remove obsolete or rarely used networks to avoid unnecessary connections.
  • Regularly review the list to maintain an optimal connection sequence.

Using Terminal Commands to Forget WiFi Networks

For users comfortable with command-line operations, the Terminal offers a quick way to manage saved WiFi networks without navigating through graphical interfaces.

The `networksetup` utility can be used to remove WiFi networks from the preferred list. The general syntax to remove a network is:

“`
sudo networksetup -removepreferredwirelessnetwork
“`

For example, if your WiFi interface is `en0` and the network to forget is `HomeWiFi`, the command is:

“`
sudo networksetup -removepreferredwirelessnetwork en0 HomeWiFi
“`

To find your WiFi interface name, use:

“`
networksetup -listallhardwareports
“`

This command lists all hardware ports and their corresponding device names.

Below is a table summarizing useful Terminal commands for managing WiFi networks:

Command Description Example
List all hardware ports Displays network interfaces and device names networksetup -listallhardwareports
Remove preferred wireless network Deletes a saved WiFi network sudo networksetup -removepreferredwirelessnetwork en0 HomeWiFi
List preferred wireless networks Shows saved WiFi networks on a specific interface networksetup -listpreferredwirelessnetworks en0

Using Terminal commands requires administrator privileges, so you may be prompted for your password. This method is efficient for managing multiple networks quickly or scripting network management tasks.

Additional Tips for WiFi Network Management on macOS

Effective WiFi management on macOS involves a few additional considerations to enhance connectivity and security:

  • Enable “Ask to Join Networks”: This setting prompts your MacBook to notify you when new networks are available, reducing automatic connections to unknown networks.
  • Regularly Update macOS: Network management features improve with updates, ensuring better security and functionality.
  • Use Keychain Access for Password Management: WiFi passwords are stored in the Keychain; managing entries here can help troubleshoot connection issues.
  • Reset Network Settings if Needed: If WiFi behaves erratically, resetting network preferences by deleting related system files can help, though it requires caution.

By thoughtfully managing saved networks and preferences, you maintain control over your MacBook’s wireless connections, improving both convenience and security.

Accessing Network Preferences to Manage Saved WiFi Networks

To forget WiFi networks on a MacBook, begin by navigating to the system settings where all network configurations are managed. This process ensures that previously connected networks will no longer automatically reconnect.

  • Click the Apple menu () located in the top-left corner of your screen.
  • Select System Settings (or System Preferences in macOS versions prior to Ventura).
  • In the settings window, locate and click on Network.
  • From the list on the left, select Wi-Fi.
  • Click the Details button next to the current Wi-Fi network name or the “Advanced” button in older macOS versions.

This opens a detailed panel showing all WiFi networks your MacBook has saved and can connect to automatically.

Removing or Forgetting Specific WiFi Networks

Once inside the detailed WiFi settings, you can manage individual networks to prevent automatic reconnection or to clear obsolete entries.

The steps to forget WiFi networks are as follows:

  • In the list of “Preferred Networks,” locate the WiFi network(s) you want to forget.
  • Select the network by clicking on its name.
  • Click the – (minus) button below the list to remove the selected network.
  • Confirm any prompts to ensure the network is deleted from your Mac’s remembered list.
  • After removing all unwanted networks, click OK or Apply to save the changes.

Removing a network from this list means your MacBook will no longer automatically connect to it unless you manually select and re-enter its password.

Additional Considerations When Managing WiFi Networks

Understanding how macOS handles WiFi networks can help maintain control over your connections, particularly in environments with many overlapping networks.

Aspect Description Impact of Forgetting Network
Auto-Join Setting Controls whether your Mac automatically connects to a known network when in range. Forgetting a network disables auto-join, requiring manual connection.
Network Password Stored credentials allow seamless connection without re-entering passwords. Forgetting a network deletes stored passwords, so re-entry is needed on next connection.
Priority Order Determines which saved networks the Mac connects to first when multiple are available. Removing networks modifies priority, potentially improving connection choices.
Profile-Based Networks Networks configured via profiles (e.g., enterprise or school networks). May require profile removal or administrator privileges to forget.

For networks installed via configuration profiles, additional steps may be necessary, such as removing the profile from System Settings > Profiles.

Forgetting WiFi Networks Using Terminal Commands

For advanced users or administrators, macOS provides command-line tools to manage WiFi network preferences. This method can be particularly useful for scripting or remote management.

To forget a WiFi network via Terminal:

  1. Open Terminal from Applications > Utilities or using Spotlight search.
  2. Identify your WiFi interface, typically named en0 or en1, with the command: 
    networksetup -listallhardwareports
  3. Use the following command to remove a saved network (replace SSID_NAME with the network’s name and en0 with your interface): 
    networksetup -removepreferredwirelessnetwork en0 "SSID_NAME"
  4. Verify removal by listing preferred networks: 
    networksetup -listpreferredwirelessnetworks en0

This method requires administrator privileges. Use sudo if necessary.

Preventing Automatic Reconnection Without Forgetting Networks

In some cases, you may want to keep a network saved but disable automatic reconnection. macOS allows this adjustment without deleting network credentials.

  • Follow the initial steps to access the list of preferred networks.
  • Select the desired network.
  • Uncheck the Auto-Join option.
  • Click OK or Apply to save.

Disabling auto-join keeps the password stored but prevents the Mac from connecting automatically when the network is in range.
