Why You Might Want to Forget a Wi-Fi Network on Mac

There are many practical reasons to remove a saved Wi-Fi network. A network may have changed its password, and your Mac keeps trying the old one. You may have connected to a hotel, airport, or cafe network once and do not want your Mac to reconnect automatically later. In some cases, a network name may be duplicated or spoofed, and removing the saved entry helps your Mac choose the correct access point. Forgetting a network can also resolve slow or unstable connections caused by a saved profile that no longer matches the router configuration.

Privacy is another common reason. On a shared or work Mac, saved networks can reveal places you have been. Removing them reduces that footprint. If you are troubleshooting, forgetting and reconnecting from scratch is often faster than digging through advanced network settings.

Before You Start: What Forgetting a Network Does

When you forget a Wi-Fi network, your Mac removes that network from its preferred networks list. It will no longer automatically join that network, and the saved password for that network on that Mac is typically removed from the local Wi-Fi configuration. However, if iCloud Keychain is enabled, the password may still be stored in your iCloud Keychain and could sync back or be available on other Apple devices. Forgetting the network on one Mac does not always remove it from every device.

It is also important to understand that forgetting a network does not delete the network itself, change your router, or affect other devices. It only changes how your Mac remembers and connects to that network. If you want a complete cleanup, you may also need to remove the password from Keychain Access and disable automatic joining for nearby networks.

Forget Wi-Fi Network on macOS Ventura and Sonoma

On macOS Ventura and Sonoma, Apple moved most network controls into the redesigned System Settings app. If you are using one of these versions, follow the steps below. This is the most common path for newer Macs, and it is where most users should start when asking how to forget a Wi-Fi network on Mac.

Step-by-Step for Ventura and Sonoma

1. Click the Apple menu in the top-left corner of your screen.
2. Select System Settings.
3. In the sidebar, click Wi-Fi.
4. Make sure Wi-Fi is turned on.
5. Look for the network you want to remove under Known Networks or in the list of available networks.
6. Click the More info button, often shown as a small circle with an “i”, next to the network name.
7. Click Forget This Network.
8. Confirm when prompted.

After you confirm, the network should disappear from your known networks list. If you are currently connected to that network, your Mac may disconnect briefly. Reconnect manually if needed, and enter the password again if the network requires one.

If you do not see the network in the list, make sure it is not hidden under a different name or that you are signed into the correct user account. Some networks may appear only when Wi-Fi is scanning nearby, while others remain in the known list even when out of range.

Forget Wi-Fi Network on macOS Monterey and Earlier

If your Mac runs macOS Monterey, Big Sur, Catalina, Mojave, or an earlier release, the path uses System Preferences instead of System Settings. The wording is slightly different, but the idea is the same: open network settings, find the saved network, and remove it.

Step-by-Step for Monterey, Big Sur, and Catalina

1. Click the Apple menu.
2. Select System Preferences.
3. Click Network.
4. Select Wi-Fi in the left sidebar.
5. Click the Advanced button.
6. In the Preferred Networks list, select the network you want to remove.
7. Click the minus button (-) below the list.
8. Click OK, then click Apply.

On older macOS versions, you may need to click Remove instead of using the minus button. The exact label varies, but the action is the same: remove the selected preferred network and apply the change.

For macOS Mojave and High Sierra, the path is very similar. Go to System Preferences, Network, Wi-Fi, Advanced, select the network, remove it, and apply. If the Apply button is grayed out, make sure you have selected the correct network and that no other dialog boxes are open.

System Settings vs System Preferences: A Quick Comparison

The method for forgetting a network depends on your macOS version. This table summarizes the main differences so you can quickly choose the right path.

macOS Version	Settings App	Path to Wi-Fi Networks	Removal Action
Sonoma / Ventura	System Settings	Wi-Fi, then Known Networks or available list	More info, then Forget This Network
Monterey / Big Sur / Catalina	System Preferences	Network, Wi-Fi, Advanced, Preferred Networks	Select network, click minus, Apply
Mojave / High Sierra	System Preferences	Network, Wi-Fi, Advanced, Preferred Networks	Select network, remove, Apply
Older releases	System Preferences	Network, Wi-Fi, Advanced	Select and remove from preferred list

If you are unsure which macOS version you are running, click the Apple menu and choose About This Mac. The version name and number appear at the top of the window.

How to Forget All Saved Wi-Fi Networks on Mac

Sometimes you do not want to remove just one network; you want a clean slate. macOS does not offer a single “forget all networks” button in the main interface, but you can remove them one by one in the Preferred Networks list. For a more thorough cleanup, you can also delete network configuration files or use Terminal commands.

To remove multiple networks manually, open the Advanced Wi-Fi settings, select each network in the Preferred Networks list, and remove it. Hold the Command key to select multiple entries if your version supports multi-selection, then remove them together. Afterward, click Apply and restart your Mac if you want to be certain the changes take effect.

If you want to reset all network settings more broadly, you can remove the system configuration files. This is more aggressive and should be used carefully. The relevant files are typically located in /Library/Preferences/SystemConfiguration/. Removing the wrong file can affect Ethernet, VPN, or Bluetooth settings. Before making changes, back up important data and consider creating a new network location first.

Remove Network Passwords from Keychain Access

Forgetting a network from Wi-Fi settings usually removes the local association, but the password may remain in Keychain Access. If you want to fully remove traces of a network, especially on a shared Mac, check Keychain Access as well.

1. Open Spotlight by pressing Command + Space.
2. Type Keychain Access and press Return.
3. In the search field, type the name of the Wi-Fi network.
4. Look for entries labeled as AirPort network passwords or Internet passwords.
5. Select the matching entry.
6. Press Delete or right-click and choose Delete.
7. Confirm the deletion.

Be careful not to delete unrelated passwords. If you are signed into iCloud Keychain, the password may also exist on your other Apple devices. In that case, removing it from one Mac may sync the deletion, but you should verify on other devices. If you do not want passwords syncing at all, review your iCloud Keychain settings in System Settings or System Preferences.

Advanced: Forget Wi-Fi Network Using Terminal

Advanced users can manage Wi-Fi networks from Terminal. This can be useful when the graphical interface is not responding, when you need to script cleanup, or when you are managing multiple Macs. Commands vary by macOS version, so use them carefully and make sure you understand what each command does before running it.

First, identify your Wi-Fi interface. It is often en0, but not always. You can list network hardware ports with the following command:

networksetup -listallhardwareports

To see saved preferred networks, use a command like this, replacing en0 if needed:

networksetup -listpreferredwirelessnetworks en0

To remove a specific network, use:

networksetup -removepreferredwirelessnetwork en0 "NetworkName"

Replace en0 with your actual Wi-Fi interface and NetworkName with the exact network name, including spaces and capitalization. After running the command, verify the removal with the list command again. You may need to enter your administrator password.

Terminal changes can be powerful. If you are not comfortable with the command line, use the graphical method instead. A typo in a network name usually just causes the command to fail, but removing the wrong interface or file can disrupt connectivity.

Troubleshooting: Wi-Fi Network Keeps Reappearing

Sometimes you forget a network, but it returns. This usually happens because the password is still stored in iCloud Keychain, because the network is being shared from another device, or because a configuration profile manages the network. Here are the most common fixes.

• Check iCloud Keychain: If the password syncs back, remove it from Keychain Access and check other Apple devices.
• Disable auto-join: Turn off automatic joining for nearby networks so your Mac does not reconnect without asking.
• Check configuration profiles: In System Settings or System Preferences, look for Profiles. A managed network may be pushed by an organization.
• Restart your Mac: A simple restart can clear cached network states.
• Reset network settings: As a last resort, remove configuration files or create a new network location.

If the network reappears immediately after you remove it, look for a device nearby that is sharing the network or a router using the same name. Your Mac may be connecting to a different access point with an identical SSID. In that case, forgetting the name removes all entries with that name, but a new identical network may still be detected.

Tips and Best Practices

A few habits make Wi-Fi management easier and safer. Keep your macOS updated so the Settings interface and security features stay current. Use strong, unique Wi-Fi passwords and avoid saving public hotspot credentials unless you trust the network. Review your known networks periodically and remove old entries. If you travel often, consider turning off automatic joining for open networks to reduce the risk of connecting to a malicious hotspot.

When troubleshooting, change one thing at a time. Forget the network, reconnect manually, and test. If the issue remains, move on to Keychain cleanup or router checks. This makes it easier to identify the real cause. Also, document important network passwords in a secure password manager rather than relying only on macOS saved credentials.

For work or school Macs, check with your IT department before removing managed networks. Some profiles are required for access to internal resources, and removing them may interrupt VPN or directory services.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete the password everywhere?

No. It removes the network from your Mac’s preferred list and usually removes the local password association, but iCloud Keychain may still store it. Check Keychain Access and other devices if you want complete removal.

Why can I not find the Forget This Network button?

You may be using an older macOS version that uses System Preferences instead of System Settings. On newer versions, click the info button next to the network. If the network is not saved, there is nothing to forget.

Can I forget a network I am currently using?

Yes, but your Mac will disconnect. You can reconnect manually afterward by selecting the network and entering the password.

How do I stop my Mac from auto-joining Wi-Fi networks?

In Wi-Fi settings, disable automatic joining for specific networks or adjust the auto-join behavior in the network details. You can also remove unwanted saved networks so your Mac cannot reconnect automatically.

Is it safe to use Terminal to remove Wi-Fi networks?

It is safe if you use the correct commands and exact network names. Terminal commands can affect system configuration, so double-check before pressing Return. If you are unsure, use the graphical method.

Will forgetting a network fix slow Wi-Fi?

Sometimes. If the saved profile is corrupted or the network changed its settings, forgetting and reconnecting can help. If the problem persists, check router placement, interference, and macOS updates.

Conclusion

Now you know how to answer the question How Forget Wifi Network on Mac? across modern and older macOS versions. Start with System Settings or System Preferences, remove the network from your preferred list, and confirm the change. If the network returns, clean up Keychain Access, check iCloud syncing, and review managed profiles. For advanced cleanup, Terminal commands and configuration resets are available, but use them carefully. With these steps, you can keep your Mac’s Wi-Fi list clean, secure, and under your control.
