What Does It Mean to Forget a WiFi Network on MacBook?

When your MacBook joins a WiFi network, macOS stores the network name, also called the SSID, along with the password and security settings in a local database. This allows the computer to reconnect automatically whenever the network is in range. Forgetting a network tells macOS to delete that saved entry from your computer’s memory. Afterward, your MacBook will not join the network automatically, and it will not offer to connect unless you manually select it and re-enter the credentials.

It is important to distinguish forgetting from simply disconnecting. Disconnecting ends your current session but keeps the network saved for later use. Forgetting removes the network from your MacBook’s list of known networks entirely. If you want to use that network again in the future, you will have to set it up as if it were brand new.

Why You Might Want to Forget a WiFi Network

There are many practical reasons to remove a saved wireless network from your MacBook. Security is a major consideration. If you connected to a public WiFi network at an airport, hotel, or coffee shop, you probably do not want your MacBook to remember it indefinitely. Old networks with outdated passwords can cause connection loops, where your MacBook keeps attempting to join and failing, which drains battery and interrupts your workflow.

If you are preparing to sell or give away your MacBook, forgetting personal and work networks protects your privacy by ensuring the next owner cannot easily reconnect to your home or office network. You might also want to clean up a long list of saved networks that makes it harder to find the one you actually need. In short, forgetting a network is a simple way to maintain control over which wireless networks your MacBook trusts.

Prerequisites Before You Begin

Before you start, make sure you are logged in to an administrator account. Standard user accounts may not be allowed to modify network preferences on some managed MacBooks, especially those issued by schools or employers. You should also know which version of macOS you are running, because the user interface changed significantly between macOS Monterey and macOS Ventura. To check, click the Apple menu in the top-left corner of your screen and select About This Mac.

You do not need to be connected to the network you want to forget, but having the exact network name handy will help you locate it in the list. If you are using a MacBook managed by an organization, there may be configuration profiles that prevent you from forgetting certain networks. In those cases, you may need to contact your IT department.

Method 1: Forget Network via System Settings (macOS Ventura and Later)

Apple redesigned the settings app in macOS Ventura, replacing the old System Preferences window with System Settings. If your MacBook is running macOS Ventura, Sonoma, or a later release, follow these steps to forget a WiFi network.

  1. Click the Apple menu in the top-left corner of your screen and choose System Settings.
  2. In the left sidebar, scroll down and click WiFi.
  3. Look for the network you want to forget. If you are currently connected to it, click the Details button next to the network name. If you are not connected, look under Known Networks and click the Details button or the three-dot menu next to the network.
  4. In the details panel that appears, look for the option labeled Forget This Network.
  5. Click Forget This Network and confirm your choice when prompted.
  6. The network will disappear from your saved list, and your MacBook will no longer attempt to join it automatically.

This method works whether the network is currently in range or not, as long as it appears in your Known Networks list. If you do not see the network, make sure WiFi is turned on and that you are viewing the complete list of known networks.

Method 2: Forget Network via System Preferences (macOS Monterey and Earlier)

If your MacBook is running macOS Monterey, Big Sur, Catalina, or an earlier version, you will use System Preferences instead of System Settings. The layout is slightly different, but the result is the same.

  1. Click the Apple menu and select System Preferences.
  2. Click the Network icon.
  3. Select WiFi from the list of interfaces on the left.
  4. Click the Advanced button in the bottom-right corner.
  5. You will see a list of Preferred Networks. Select the network you want to forget from the list.
  6. Click the remove button, which looks like a minus sign (-), below the list.
  7. Click OK to close the Advanced sheet, then click Apply to save your changes.

After completing these steps, the selected network will be removed from your MacBook’s preferred networks list. If you ever want to join it again, you will need to select it from the WiFi menu and enter the password manually.

Method 3: Forget Network Using Terminal (Advanced Users)

For users who prefer the command line or need to script network management, macOS provides the networksetup utility in Terminal. This method is especially useful when you want to remove multiple networks quickly or when the graphical interface is not responding.

  1. Open Terminal. You can find it in Applications > Utilities, or by searching with Spotlight.
  2. Type the following command to list your preferred wireless networks and press Enter:
networksetup -listpreferredwirelessnetworks en0
  1. Identify the exact name of the network you want to forget from the output.
  2. Type the following command, replacing “NetworkName” with the actual SSID, and press Enter:
networksetup -removepreferredwirelessnetwork en0 "NetworkName"
  1. If prompted, enter your administrator password. Note that Terminal will not show characters as you type.
  2. Restart WiFi or wait a few moments for the change to take effect.

On most MacBooks, en0 is the built-in WiFi interface. If you are using an external USB or Thunderbolt WiFi adapter, the interface name might be en1 or en2. You can run networksetup -listallhardwareports to confirm which identifier corresponds to WiFi.

How to Forget a Network Your MacBook Is Not Currently Connected To

One common misconception is that you must be connected to a WiFi network before you can forget it. That is not true. macOS keeps a list of known networks even when they are out of range. Both the System Settings method and the System Preferences method allow you to remove networks from this list regardless of your current connection status.

In macOS Ventura and later, look under the Known Networks section in the WiFi settings. In macOS Monterey and earlier, look under Preferred Networks in the Advanced WiFi sheet. Select the network you want to remove and follow the same steps described above. Your MacBook will forget the network and stop attempting to join it automatically the next time it comes within range.

How to Reconnect to a Forgotten WiFi Network

Forgetting a network is not permanent. If you change your mind or need to reconnect later, you can add the network back at any time. Click the WiFi icon in the menu bar or open Control Center and select WiFi. Choose the network from the list of available networks. If the network does not appear, make sure it is broadcasting its SSID and is within range.

When you select the network, macOS will prompt you to enter the password. Once you enter it correctly and join, the network will be saved again and your MacBook may reconnect automatically in the future, depending on your settings. If you want to prevent automatic rejoining, you can uncheck the auto-join option during the connection process or adjust it later in the network details.

Troubleshooting: Network Still Appears or Will Not Forget

Sometimes a network seems to stick around even after you try to forget it. If the network still appears in your list, first confirm that you actually clicked Forget or Remove and then clicked Apply or OK. Changes in System Preferences are not saved until you click Apply.

If the network reappears on other Apple devices, iCloud Keychain may be syncing your saved WiFi networks across your iPhone, iPad, and Mac. Forgetting the network on your MacBook does not automatically remove it from your other devices unless you disable iCloud Keychain syncing for passwords.

If the Forget This Network option is grayed out or missing, your MacBook may be managed by a mobile device management (MDM) profile installed by your employer or school. These profiles can enforce specific WiFi settings that users are not allowed to change. In that case, contact your IT administrator for assistance.

As a last resort, restart your MacBook and try again. If the problem persists, you can boot into Safe Mode to see if a third-party application or login item is interfering with network preferences.

Comparison: Forget vs. Disconnect vs. Remove Profile

It helps to understand how forgetting a network differs from other wireless actions. The table below compares the most common options.

Action What It Does Best For Reversible?
Disconnect Ends the current connection but keeps the network saved. Taking a short break from a network. Yes, reconnect anytime.
Forget This Network Deletes the saved SSID and password from your MacBook. Privacy, old networks, wrong passwords. Yes, by rejoining manually.
Remove Configuration Profile Removes enterprise or corporate WiFi settings installed by MDM. Work or school networks with restrictions. May require IT department.
Turn Off WiFi Disables all wireless networking on the MacBook. Airplane mode, saving battery, troubleshooting. Yes, turn WiFi back on.

Tips and Best Practices for Managing WiFi Networks on MacBook

Managing your saved networks is an ongoing task, not a one-time event. Here are some best practices to keep your MacBook’s wireless settings clean and secure.

  • Review your known networks regularly. Every few months, check your list of saved networks and forget any you no longer use.
  • Forget public networks after use. If you connect to airport, hotel, or cafe WiFi, forget the network when you leave to prevent automatic reconnection in the future.
  • Use Private WiFi Address. Modern macOS versions offer a Private WiFi Address feature that improves privacy by rotating your device’s MAC address on supported networks.
  • Check Keychain Access for saved passwords. If you forget a network but later need the password, you can often find it in Keychain Access under the System category.
  • Turn off Ask to Join Networks if needed. If your MacBook constantly prompts you to join nearby networks, disable this option in WiFi settings to reduce interruptions.
  • Be cautious with enterprise networks. Work or school networks may use certificates and profiles. Forgetting them might require additional steps to reconnect, so consult your IT team first.

Frequently Asked Questions

Will forgetting a network delete the password from my iCloud Keychain?

Forgetting a network removes it from your MacBook’s saved list. If you use iCloud Keychain, the password may still exist on your other Apple devices. You would need to remove it from each device individually or manage it through iCloud settings.

Can I forget multiple networks at once?

macOS does not provide a bulk forget button in the graphical interface. You must remove networks one by one through System Settings or System Preferences. Advanced users can write a Terminal script to remove multiple networks in sequence.

What if the network name is hidden?

Hidden networks still appear in your preferred networks list if you have joined them before. You can forget them using the same steps as any other saved network.

Does forgetting a network affect other devices?

No. Forgetting a network on your MacBook only affects that specific computer. Your iPhone, iPad, or other devices will still remember the network unless you forget it on them as well.

How do I stop my MacBook from asking to join networks?

Open System Settings or System Preferences, go to WiFi, and look for the option labeled Ask to join networks. Turn it off to stop automatic prompts.

Can I forget a network I am currently connected to?

Yes. When you confirm Forget This Network, your MacBook will disconnect immediately and remove the network from memory.

What is the difference between en0 and en1 in Terminal commands?

en0 is typically the built-in WiFi interface on most MacBooks. en1 or higher usually refers to external network adapters or additional interfaces. Run networksetup -listallhardwareports to identify the correct interface for your MacBook.

Will resetting network settings forget all WiFi networks?

Yes. A full network reset removes saved WiFi networks, Bluetooth pairings, VPN configurations, and other networking preferences. Use this option only if you are prepared to set everything up again.
