Introduction

Mac computers are designed to remember every Wi-Fi network you join. That convenience means your Mac will automatically reconnect to your home network, office network, or favorite coffee shop hotspot whenever it is in range. However, there are many situations where that saved memory becomes more of a liability than a feature. You might have changed your Wi-Fi password, moved to a new apartment, or connected to a public network that you never want to join again. In those cases, knowing How to Forget Mac Wifi? is an essential skill for any macOS user.

Forgetting a Wi-Fi network is not the same as simply turning off Wi-Fi or disconnecting from a network. When you forget a network, macOS removes it from the list of preferred networks, deletes the saved password from your keychain, and stops your Mac from automatically joining it in the future. The network may still appear in the list of available networks, but your Mac will not connect to it unless you manually select it and re-enter the credentials.

This guide walks you through every method for forgetting Wi-Fi networks on macOS, whether you are running the latest version of macOS Ventura or an older release such as Monterey or Big Sur. You will learn how to use System Settings, System Preferences, the menu bar, Terminal, and Keychain Access. We will also cover what happens after you forget a network, how to troubleshoot networks that refuse to disappear, and best practices for keeping your wireless network list clean and secure.

What Does It Mean to Forget a Wi-Fi Network on Mac?

When your Mac joins a Wi-Fi network for the first time, macOS stores several pieces of information about that network. It saves the network name, also known as the SSID, the security type, and the password. It also marks the network as a preferred network, which means your Mac will attempt to connect to it automatically whenever the signal is detected. This information is stored in the system configuration and, in many cases, in the macOS Keychain.

Forgetting a network tells macOS to remove that stored information. Once a network is forgotten, it is no longer in the preferred networks list. Your Mac will not attempt to auto-join it, and the saved password is typically removed. If you want to join that network again later, you will need to select it from the available networks list and enter the password from scratch.

It is important to understand that forgetting a network does not delete the network itself. The router or access point still exists. It also does not affect other devices on the same network. Your iPhone, iPad, or Windows laptop will continue to remember the network unless you forget it on those devices as well.

Why You Might Want to Forget a Wi-Fi Network

There are many practical reasons to remove a saved Wi-Fi network from your Mac. Understanding these reasons can help you decide when it is time to clean up your network list.

  • Changed passwords: If you updated your home Wi-Fi password, your Mac may keep trying to connect with the old credentials, causing repeated connection failures.
  • Old or unused networks: Networks from former workplaces, previous apartments, or schools you no longer attend clutter your list and can cause confusion.
  • Security concerns: Public Wi-Fi networks at airports, hotels, or cafes should not remain on your Mac indefinitely. Forgetting them reduces the risk of your device automatically joining an unsecured network.
  • Troubleshooting connectivity: If your Mac cannot connect to a network you previously joined, forgetting the network and reconnecting fresh can resolve authentication or configuration errors.
  • Roaming issues: If you have multiple networks with similar names, your Mac might jump between them unexpectedly. Removing unwanted networks helps your Mac connect to the right one.

Regardless of the reason, learning How to Forget Mac Wifi? gives you more control over your device’s wireless behavior and improves both privacy and performance.

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

Apple redesigned the settings interface with macOS Ventura. If you are using macOS Ventura, Sonoma, or a later release, you will use System Settings instead of the older System Preferences. Follow these steps to forget a Wi-Fi network.

  1. Click the Apple menu in the top-left corner of your screen and select System Settings.
  2. In the sidebar, click Wi-Fi. If you do not see Wi-Fi immediately, scroll down or use the search field at the top of the sidebar.
  3. Look for the network you want to forget. Next to the network name, click the Details button, which looks like a small circle with three dots or an i icon depending on your macOS version.
  4. A panel will open with information about that network. Look for an option labeled Remove From This Mac or Forget This Network.
  5. Click that option. macOS may ask you to confirm your choice. Confirm to remove the network.
  6. The network will disappear from your preferred networks list. It may still appear under available networks if it is within range, but your Mac will not connect to it automatically.

This method is the most straightforward approach for modern Macs. If you are unsure which version of macOS you are running, click the Apple menu and select About This Mac or System Settings > General > About to check.

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

If your Mac is running macOS Monterey, Big Sur, Catalina, or an earlier version, you will use System Preferences instead of System Settings. The process is slightly different but still simple.

  1. Click the Apple menu in the top-left corner and choose System Preferences.
  2. Click the Network icon.
  3. In the left-hand list, select Wi-Fi.
  4. Click the Advanced… button in the bottom-right corner of the window.
  5. A new sheet will open with a tab labeled Wi-Fi. Under the Preferred Networks section, you will see a list of every network your Mac remembers.
  6. Select the network you want to forget from the list.
  7. Click the Remove button, which looks like a minus sign (–) below the list.
  8. Click OK to save your changes, then click Apply in the main Network window.

After completing these steps, the network is removed from your Mac’s preferred list. If you later decide you want to rejoin it, you will need to enter the password again.

How to Forget Mac Wifi? Using the Menu Bar

The Wi-Fi icon in the macOS menu bar provides quick access to wireless connections, but it does not always provide a direct way to forget a network. On most modern versions of macOS, clicking the Wi-Fi icon lets you turn Wi-Fi on or off, select a network, or open Network settings. It does not usually show a “Forget” option directly.

However, you can use the menu bar as a starting point. Click the Wi-Fi icon and choose Network Settings or Open Network Preferences, depending on your macOS version. From there, follow the steps outlined in the System Settings or System Preferences sections above. On some older versions of macOS, holding the Option key while clicking the Wi-Fi icon may reveal additional diagnostic information, but it still will not let you forget a network directly from the menu.

If you are looking for the fastest path, use the keyboard shortcut Command + Space to open Spotlight, type Network, and press Enter to jump directly to the network settings.

How to Forget Mac Wifi? Using Terminal

Advanced users and IT administrators may prefer to forget Wi-Fi networks using the Terminal. This method is especially useful when managing multiple Macs or when the graphical interface is not responding. The primary command for managing preferred wireless networks is networksetup.

Before you can remove a network, you need to know the name of your Wi-Fi hardware port. On most Macs, it is en0, but it can vary. Open Terminal from Applications > Utilities and run the following command:

networksetup -listallhardwareports

Look for the entry labeled Wi-Fi or AirPort and note the device name, such as en0. Once you have the hardware port, use this command to forget a specific network:

networksetup -removepreferredwirelessnetwork en0 "NetworkName"

Replace en0 with your actual hardware port and NetworkName with the exact SSID of the network you want to remove. If the network name contains spaces, keep it inside quotation marks.

To verify that the network has been removed, you can list all preferred networks with this command:

networksetup -listpreferredwirelessnetworks en0

Terminal does not provide a confirmation dialog, so double-check the network name before pressing Enter. This method removes the network from the preferred list, but you may still need to remove the password from Keychain Access for a complete cleanup, which we cover in the next section.

How to Forget Mac Wifi? Removing Saved Passwords from Keychain

Even after you remove a Wi-Fi network from your preferred networks list, macOS may still store the password in Keychain Access. This means that if you ever rejoin the network, your Mac might offer to fill in the old password automatically. For a thorough removal, especially if you are troubleshooting authentication issues or concerned about security, you should delete the network password from Keychain as well.

  1. Open Keychain Access. You can find it in Applications > Utilities, or by using Spotlight search.
  2. In the Keychain Access window, look at the top-right search field and type the name of the Wi-Fi network you want to forget.
  3. Look for results labeled as AirPort network password or Wi-Fi password. These entries correspond to saved wireless network credentials.
  4. Select the entry or entries for the network you want to remove.
  5. Press the Delete key or right-click and choose Delete.
  6. If prompted, enter your Mac administrator password to confirm the deletion.
  7. Close Keychain Access.

After deleting the keychain entry, the network is completely forgotten by your Mac. No password remains stored, and your Mac will not attempt to authenticate with that network automatically.

Comparison: Forgetting vs. Disconnecting vs. Turning Off Wi-Fi

Many Mac users confuse forgetting a network with simply disconnecting from it or turning off Wi-Fi entirely. These actions have very different effects. The table below explains the differences so you can choose the right option for your situation.

Action What It Does Auto-Rejoin Later? Password Saved? Best For
Forget Network Removes the network from preferred networks and deletes saved credentials. No, not unless you re-add it manually. No Old networks, changed passwords, public Wi-Fi you will not use again.
Disconnect Drops the current connection but keeps the network in the preferred list. Yes, macOS may reconnect automatically. Yes Temporarily leaving a network you still use regularly.
Turn Off Wi-Fi Disables the wireless radio entirely. No networks can connect. N/A while Wi-Fi is off. Yes, all saved passwords remain. Saving battery, avoiding all wireless connections temporarily.

As the table shows, forgetting a network is the only option that permanently removes the saved password and prevents automatic reconnection. Use it when you are certain you do not want your Mac to remember that wireless network anymore.

What Happens After You Forget a Network?

Once you forget a Wi-Fi network on your Mac, several things change immediately. First, the network is removed from the list of preferred networks in System Settings or System Preferences. Second, the saved password is deleted from your keychain if you followed the Keychain Access steps. Third, your Mac will stop attempting to connect to that network automatically, even if the signal is strong.

The network may still appear in the list of available networks when you click the Wi-Fi icon in the menu bar. This is normal. Your Mac scans for all nearby wireless networks, whether it remembers them or not. If you click on a forgotten network, macOS will prompt you to enter the password as if you were joining for the first time.

If you use iCloud Keychain and have other Apple devices signed in with the same Apple ID, forgetting a network on your Mac may not remove it from your iPhone or iPad. Each device maintains its own network preferences unless you manage them individually. Keep this in mind if you are trying to fully remove a network from your entire Apple ecosystem.

Troubleshooting: Network Won’t Forget or Keeps Reappearing

Occasionally, a Mac user will follow the steps to forget a Wi-Fi network only to find that it reappears later or refuses to be removed. Here are the most common causes and how to fix them.

iCloud Keychain syncing: If iCloud Keychain is enabled, your Wi-Fi passwords may sync across your Apple devices. A network you forget on your Mac could reappear if another device, such as an iPhone, still remembers it and syncs the credential back. To prevent this, forget the network on all your Apple devices or temporarily disable iCloud Keychain for passwords.

Enterprise or managed networks: If your Mac is managed by an organization using a mobile device management (MDM) profile, certain Wi-Fi networks may be pushed to your Mac automatically. You may not be able to forget these networks until the profile is removed or updated by your IT administrator.

Cached network data: Sometimes macOS holds onto network information in memory. If a network will not forget, restart your Mac and try the removal process again. After rebooting, check System Settings or System Preferences to confirm the network is gone.

Incorrect network name: When using Terminal, a small typo in the SSID will cause the command to fail silently or remove the wrong network. Double-check the exact capitalization and spelling of the network name.

Multiple user accounts: Wi-Fi preferences are generally stored at the system level, but if you share your Mac with other users, check that you are logged into an administrator account. Standard user accounts may not have permission to modify network settings.

How to Reconnect to a Forgotten Network

Forgetting a network is not permanent. If you change your mind or need to rejoin a network you previously removed, the process is straightforward.

  1. Click the Wi-Fi icon in the menu bar.
  2. Look for the network name in the list of available networks.
  3. Click the network name.
  4. If the network is secured, enter the password when prompted.
  5. Choose whether you want your Mac to remember this network. If you select the option to remember it, the network will be added back to your preferred networks list.
  6. Click Join or Connect.

After reconnecting, your Mac will store the password again and may auto-join the network in the future, depending on the settings you choose during the connection process.

Tips and Best Practices for Managing Wi-Fi Networks on Mac

Keeping your Mac’s Wi-Fi network list clean can improve connectivity, security, and battery life. Here are some best practices to follow.

  • Review your preferred networks regularly: Every few months, open System Settings or System Preferences and remove networks you no longer use. This is especially important if you travel frequently and connect to many temporary networks.
  • Be cautious with public Wi-Fi: Always forget public networks at hotels, airports, and cafes after you leave. This prevents your Mac from automatically joining a network with the same name that could be malicious.
  • Use strong, unique passwords: When you reconnect to a forgotten network, make sure you are using the current password. If you suspect a network has been compromised, forget it and ask the network administrator for updated credentials.
  • Label your networks: If you manage multiple networks at home or work, give them distinct names so you do not accidentally forget the wrong one.
  • Keep macOS updated: Apple occasionally changes how Wi-Fi settings are managed. Keeping your Mac updated ensures you have the latest tools and security patches for wireless networking.
  • Document important passwords: Before you forget a network, make sure you know the password or have it stored in a password manager. Forgetting a network also removes the saved password, so you do not want to lock yourself out.

By making network cleanup a regular habit, you will always know exactly which networks your Mac trusts, and you will avoid the frustration of connecting to outdated or incorrect wireless access points.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete the password from my Mac?
Yes, forgetting a network removes the saved password from your Mac’s preferred networks list. If you want to ensure the password is completely gone, you should also delete the entry from Keychain Access.

Will forgetting a network on my Mac also forget it on my iPhone?
No. Each Apple device manages its own Wi-Fi preferences. Unless you are using a specific syncing feature and manage settings across devices, you must forget the network separately on your iPhone, iPad, and Mac.

Can I forget multiple Wi-Fi networks at once?
In System Preferences on older macOS versions, you can select multiple networks in the Advanced Wi-Fi panel and remove them one by one. In System Settings on newer macOS versions, you generally remove them individually. Terminal can remove networks one at a time per command.

What is the difference between forgetting a network and turning off Wi-Fi?
Turning off Wi-Fi disables the wireless radio temporarily. Forgetting a network removes a specific network from your Mac’s memory while leaving Wi-Fi turned on.

Why does a forgotten network still appear in my available networks list?
Your Mac scans for all nearby Wi-Fi networks, whether it remembers them or not. A forgotten network may still appear as an available option, but your Mac will not connect to it automatically.

Can I forget a network that is not currently in range?
Yes. Saved networks remain in your preferred list even when they are out of range. You can forget them at any time through System Settings, System Preferences, or Terminal.

What should I do if I forget my home Wi-Fi network by mistake?
Simply click the Wi-Fi icon in the menu bar, select your home network, enter the password, and choose to remember it. Your Mac will reconnect and save the credentials again.

Is it safe to forget public Wi-Fi networks?
Yes. Forgetting public Wi-Fi networks is a good security practice. It prevents your Mac from automatically joining a network with a similar name in the future, which could be a security risk.
