Introduction

Mac computers are designed to remember every wireless network you join. From your home router to the coffee shop down the street, your device stores network names, passwords, and security settings so you can reconnect without typing credentials every time. While this convenience is helpful, it can also lead to a cluttered list of saved networks, outdated credentials, and potential security risks. That is why knowing How to Forget Wifi on Mac? is a valuable skill for every macOS user.

Over time, your Mac may attempt to connect to networks you no longer use, or it might keep trying to join a network with an old password after you have changed it. These situations can cause slow connections, repeated authentication prompts, and unnecessary frustration. Forgetting a WiFi network removes it from your Mac’s memory, giving you a clean slate and better control over your wireless connections.

This guide covers every method available for forgetting a WiFi network on Mac, whether you are using the latest macOS Ventura or an older release such as Monterey, Big Sur, or Catalina. You will find step-by-step instructions for System Settings, System Preferences, Keychain Access, and Terminal. We also explain what happens after you forget a network, how to troubleshoot common problems, and the best practices for keeping your wireless list organized.

Why You Might Want to Forget a WiFi Network on Mac

There are many practical reasons to remove a saved wireless network from your Mac. Understanding these scenarios helps you decide when it is time to clean up your network list and take control of your connections.

One of the most common reasons is security. If you have connected to public WiFi networks at airports, hotels, or cafes, your Mac may remember them and attempt to join automatically when in range. Some of these networks are unsecured, and automatic connections can expose your device to risks. Forgetting these networks prevents your Mac from joining them without your permission.

Another reason is changed passwords. When the password for a network you use regularly is updated, your Mac may keep trying to connect with the old credentials. This results in repeated connection failures and annoying prompts. Learning How to Forget Wifi on Mac? lets you remove the outdated entry and start fresh with the correct password.

Network troubleshooting is another important scenario. If you are experiencing slow speeds, intermittent drops, or inability to connect to a specific router, removing and rejoining the network can clear corrupted settings. Forgetting the network is often the first step in resolving stubborn wireless issues.

Over time, Macs accumulate networks from places you no longer visit. Former workplaces, old apartments, and previous schools can clutter your preferred networks list. Removing these entries makes it easier to find and manage the networks that actually matter to you.

Finally, privacy matters. A long list of saved networks can reveal where you have been. If you share your Mac or simply want to minimize the information stored about your location history, forgetting sensitive or personal networks is a smart move.

What Happens When You Forget a WiFi Network

Before you remove a network, it is useful to understand exactly what forgetting does and does not do. When you tell your Mac to forget a WiFi network, several things happen behind the scenes.

First, the network is removed from your list of known or preferred networks. Your Mac will no longer attempt to join it automatically when it comes within range. Second, the saved password and security settings associated with that network are deleted. If you want to connect again in the future, you will need to enter the password from scratch.

Third, forgetting a network does not affect your other saved networks. Each entry is independent, so removing one does not impact the rest. Fourth, this action does not delete any personal files, applications, or system settings. It is strictly limited to wireless network preferences.

It is also important to know that forgetting a network does not hide it from WiFi scans. Your Mac will still detect the network when searching for available connections. It simply will not connect automatically unless you manually select it and provide the credentials again.

Overall, forgetting a network is a safe and reversible action. If you change your mind, you can always reconnect by selecting the network from the WiFi menu and entering the password.

How to Forget Wifi on Mac? Using System Settings (macOS Ventura and Later)

Apple introduced a redesigned System Settings app with macOS Ventura. If you are using Ventura, Sonoma, or any later version, the interface looks more like iOS, with a sidebar and detailed panels. Follow these steps to forget a WiFi network using System Settings.

  1. Click the Apple menu in the top-left corner of your screen.
  2. Select System Settings from the dropdown menu.
  3. In the left sidebar, scroll down and click Wi-Fi.
  4. On the right side, you will see a list of available and remembered networks.
  5. If the network you want to forget is visible, click the Details button next to it. If you do not see it, click Advanced at the bottom right of the window.
  6. In the Advanced Wi-Fi settings, locate the section labeled Known Networks.
  7. Find the network name in the list.
  8. Move your pointer over the network and click the More button, which appears as three dots.
  9. Choose Remove from List or Forget This Network, depending on the exact wording in your macOS version.
  10. Confirm your choice when the system asks if you are sure.

After you confirm, the network disappears from your known networks list. Your Mac will no longer join it automatically. If you ever want to reconnect, you can select the network from the WiFi menu and enter the password again.

This is the most straightforward way to answer How to Forget Wifi on Mac? for users on modern versions of macOS.

How to Forget Wifi on Mac? Using System Preferences (macOS Monterey and Earlier)

Macs running macOS Monterey, Big Sur, Catalina, Mojave, or earlier use System Preferences instead of System Settings. The layout is different, but the process is just as simple. Here is how to forget a WiFi network on older versions of macOS.

  1. Click the Apple menu in the top-left corner.
  2. Choose System Preferences.
  3. Click the Network icon.
  4. In the left-hand panel, select Wi-Fi.
  5. Click the Advanced... button located in the bottom right corner.
  6. A new sheet opens with several tabs. Make sure the Wi-Fi tab is selected.
  7. You will see a list labeled Preferred Networks containing every wireless network your Mac remembers.
  8. Click on the network you want to remove to highlight it.
  9. Click the minus (–) button below the list.
  10. Click Remove to confirm the deletion.
  11. Click OK to close the Advanced sheet.
  12. Click Apply to save your changes.

The network is now removed from your Mac’s preferred networks. It will not connect automatically until you add it again manually. This method works reliably on older Macs and older operating systems, making it a dependable option when you need to know How to Forget Wifi on Mac? without upgrading your software.

How to Forget Wifi on Mac? Using Keychain Access

Sometimes a WiFi network refuses to disappear because its password is stored in the macOS keychain. The keychain is a secure storage area for passwords, certificates, and other sensitive data. If standard removal methods leave traces behind, Keychain Access can help you erase the saved credentials completely.

  1. Open Finder.
  2. Navigate to Applications, then open the Utilities folder.
  3. Double-click Keychain Access to launch it.
  4. In the upper right search field, type the name of the WiFi network you want to forget.
  5. Look for results labeled as AirPort network passwords or entries that match the network name exactly.
  6. Right-click or Control-click the matching entry.
  7. Select Delete from the context menu.
  8. If prompted, enter your administrator password to authorize the deletion.
  9. Close Keychain Access and restart your Mac if the network still appears in your WiFi list.

This method is particularly useful when a network password has changed and your Mac keeps trying to authenticate with old credentials. By removing the keychain entry, you ensure that no saved password remains to cause conflicts.

If you are still wondering How to Forget Wifi on Mac? and the graphical settings did not fully solve the problem, Keychain Access is often the missing piece.

How to Forget Wifi on Mac? Using Terminal

Advanced users and IT professionals often prefer the command line for managing system settings. Terminal provides a fast, scriptable way to remove wireless networks without navigating through multiple menus. This method works across most versions of macOS.

  1. Open Terminal. You can find it in Applications > Utilities, or by using Spotlight search.
  2. Type the following command to display all remembered wireless networks:
    networksetup -listpreferredwirelessnetworks en0
  3. Press Enter. Review the list and note the exact name of the network you want to remove.
  4. Type the removal command, replacing NETWORK_NAME with the actual name of the network:
    networksetup -removepreferredwirelessnetwork en0 "NETWORK_NAME"
  5. Press Enter.
  6. If asked, enter your administrator password. Note that Terminal does not show characters as you type passwords.
  7. Run the list command again to verify that the network is gone.

On most Macs, the WiFi interface is en0. However, if you have multiple network adapters, your WiFi might be en1 or another identifier. You can check all hardware ports by running:
networksetup -listallhardwareports

For users comfortable with the command line, this is one of the fastest ways to handle How to Forget Wifi on Mac? without using a mouse at all.

Forgetting the Network You’re Currently Connected To

A common question is whether you can forget a WiFi network while you are actively connected to it. The answer is yes. Your Mac allows you to remove a network from memory even if you are using it right now, though the connection will end once the removal is confirmed.

On macOS Ventura and later:

  1. Open System Settings and navigate to Wi-Fi.
  2. Find your current network in the list.
  3. Click the Details button next to the network name.
  4. Look for the option labeled Forget This Network or Remove from List.
  5. Click it and confirm your choice.
  6. Your Mac will disconnect from the network immediately.

On macOS Monterey and earlier:

  1. Open System Preferences and click Network.
  2. Select Wi-Fi in the left sidebar.
  3. Click Advanced....
  4. In the Preferred Networks list, select your current network.
  5. Click the minus (–) button and then click Remove.
  6. Click OK, then click Apply.

Afterward, your Mac will no longer remember the network. If you need to get back online, choose a different network from the WiFi menu or re-enter the password for the same network if you want to reconnect.

Forgetting Hidden WiFi Networks and Removing All Networks

Hidden networks do not broadcast their names, which means they do not always appear in the standard WiFi menu. However, your Mac can still remember them if you have joined them before. To forget a hidden network, you must access the list of known networks directly.

On macOS Ventura and later, open System Settings, go to Wi-Fi, and click Advanced. Look through the Known Networks list for entries that do not have a clear name or that match the hidden network you joined previously. Remove them using the three-dot menu as described earlier.

On macOS Monterey and earlier, open System Preferences, go to Network, select Wi-Fi, and click Advanced.... The Preferred Networks list may include hidden networks. Select them and click the minus button to remove them.

If your goal is to remove every saved WiFi network at once, there is no single “Forget All” button in the graphical interface. You must delete networks one by one through System Settings or System Preferences. Alternatively, you can use Terminal to clear the entire preferred networks list with a loop command.

for ssid in $(networksetup -listpreferredwirelessnetworks en0 | tail -n +2); do
  networksetup -removepreferredwirelessnetwork en0 "$ssid"
done

Use this command with caution. It will delete every remembered wireless network, and you will need to re-enter passwords for any network you want to join again.

Whether you are dealing with a single hidden network or clearing your entire list, these methods ensure that you fully understand How to Forget Wifi on Mac? in every situation.

Troubleshooting Common Problems When You Forget WiFi on Mac

Even with clear instructions, things do not always go as expected. Here are the most common issues users encounter and how to resolve them.

The network will not disappear from the list. If you remove a network but it still appears, restart your Mac and try again. You should also check Keychain Access for any saved passwords related to that network and delete them manually. If the problem persists, use the Terminal removal command described earlier.

Your Mac keeps connecting automatically after forgetting. This usually means the network is still in your preferred list or that auto-join is enabled. Double-check that you actually removed the network and not just disconnected from it. If you are using a work-managed Mac, your organization may have policies that prevent certain networks from being forgotten.

The Forget option is greyed out. This typically happens when you are logged in as a standard user without administrator privileges. Log in with an admin account or contact your IT support team for assistance.

You cannot reconnect after forgetting. Remember that forgetting deletes the saved password. When you try to join the network again, you will be prompted to enter the password. Make sure you have the correct credentials before you forget a network you use regularly.

Hidden networks do not appear in the WiFi menu. Hidden networks are not broadcast, so they will not show up in the normal scan. You must manage them through the Known Networks or Preferred Networks list in System Settings or System Preferences.

By knowing these troubleshooting steps, you can confidently handle How to Forget Wifi on Mac? even when something goes wrong.

Tips and Best Practices for WiFi Management on Mac

Keeping your wireless network list clean requires more than just knowing how to remove networks. These best practices will help you maintain a secure and organized connection history.

  • Review your saved networks regularly. Every few months, open your WiFi settings and remove networks you no longer use. This prevents your list from growing too large.
  • Turn off auto-join for public networks. When you connect to airport, hotel, or cafe WiFi, disable automatic joining so your Mac does not remember the network permanently.
  • Keep passwords in a safe place. Before you forget a network you use often, make sure you know the password or have it stored in a password manager.
  • Use clear network names. If you manage multiple routers at home or in the office, give them descriptive names so you do not accidentally forget the wrong one.
  • Keep macOS updated. Newer versions include improved WiFi management tools, security updates, and bug fixes that can prevent connection problems.

Following these tips reduces how often you need to ask How to Forget Wifi on Mac? because your saved networks will stay relevant and easy to manage.
