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

There are many practical reasons to remove a saved Wi-Fi network from your Mac. Understanding these scenarios can help you decide when forgetting a network is the right solution.

• Wrong network priority: Your Mac may automatically join a slow or unreliable network instead of your preferred one because it remembers both.
• Changed passwords: If a network’s password has been updated and your Mac keeps trying to connect with the old credentials, forgetting the network lets you enter the new password cleanly.
• Security and privacy: Removing networks you no longer use—such as public hotspots, hotel Wi-Fi, or a former workplace network—reduces the risk of your Mac automatically connecting to unsecured or spoofed networks.
• Troubleshooting connection issues: Corrupted network settings can cause dropped connections, slow speeds, or failure to obtain an IP address. Forgetting and rejoining the network often resolves these problems.
• Decluttering your network list: Over time, your Mac accumulates dozens of saved networks. Cleaning up the list makes it easier to manage your connections.

Before You Begin: What Happens When You Forget a Network

Before you learn How to Forget Wifi Network Mac? using the steps below, it helps to understand exactly what happens when you remove a network:

• The saved password is deleted: Your Mac will no longer remember the Wi-Fi password. You will need to enter it again if you want to reconnect.
• Auto-join is disabled: Your Mac will stop automatically connecting to that network when it is in range.
• Network-specific settings are removed: Any custom DNS, proxy, or other network configurations tied to that Wi-Fi network are cleared from your Mac’s local settings.
• iCloud Keychain may sync the change: If you use iCloud Keychain, forgetting a network on your Mac can also remove it from your other Apple devices signed in with the same Apple ID. You can manage this behavior in your iCloud settings.

If you think you might need the password later, make sure you have it written down or stored in a password manager before proceeding.

How to Forget a Wi-Fi Network on macOS Ventura, Sonoma, and Later

Starting with macOS Ventura, Apple replaced System Preferences with System Settings, which changed the layout of Wi-Fi controls. If you are running macOS Ventura, Sonoma, Sequoia, or a later version, follow these steps to forget a Wi-Fi network.

Step-by-Step Instructions

1. Open System Settings: Click the Apple menu () in the top-left corner of your screen and select System Settings. You can also click the System Settings icon in your Dock if it is there.
2. Select Wi-Fi: In the left sidebar, click Wi-Fi. Make sure Wi-Fi is turned on so you can see your network options.
3. Open Known Networks: Look for the Known Networks section and click the Details button (or Advanced, depending on your macOS version) next to it. This opens a list of all Wi-Fi networks your Mac has saved.
4. Find the network you want to remove: Scroll through the list or use the search field to locate the network you want to forget.
5. Forget the network: Click the three-dot menu (More button) next to the network name and select Forget This Network. Alternatively, on some versions, you can click the minus (–) button or select the network and confirm removal.
6. Confirm your choice: A dialog box will appear asking you to confirm. Click Remove or Forget to finalize the action.
7. Close System Settings: Your Mac will no longer automatically connect to that network.

This method is the most straightforward way to answer the question, “How to Forget Wifi Network Mac?” on modern versions of macOS.

How to Forget a Wi-Fi Network on macOS Monterey and Earlier

If your Mac is running macOS Monterey, Big Sur, Catalina, Mojave, or an earlier version, you will use the classic System Preferences interface. The process is slightly different but just as simple.

Step-by-Step Instructions

1. Open System Preferences: Click the Apple menu () and choose System Preferences.
2. Go to Network: Click the Network icon in the System Preferences window.

Once you click Apply, the network is removed from your Mac’s saved list and will not connect automatically.

How to Quickly Disconnect vs. Forget a Network from the Menu Bar

Many users click the Wi-Fi icon in the menu bar to manage their connections, but it is important to understand the difference between disconnecting from a network and forgetting it.

• Disconnecting: Clicking the Wi-Fi icon and selecting a different network (or turning Wi-Fi off) only disconnects you temporarily. Your Mac will still remember the network and may reconnect automatically later.
• Forgetting: Forgetting a network removes its saved credentials entirely. This requires going into System Settings or System Preferences, or using Terminal, as described in the sections above.

On recent versions of macOS, you can click the Wi-Fi icon in the menu bar, then click Wi-Fi Settings (or Network Settings) to jump directly to the Wi-Fi settings panel. From there, you can access Known Networks and remove the network you no longer want. This shortcut saves time compared to navigating through the Apple menu.

How to Remove All Saved Wi-Fi Networks at Once

If you want a completely fresh start, you can remove all saved Wi-Fi networks from your Mac. This is useful when troubleshooting persistent connectivity issues, preparing a Mac for a new user, or clearing out years of accumulated networks.

Using System Settings or System Preferences

1. Open the Known Networks (macOS Ventura and later) or Preferred Networks (macOS Monterey and earlier) list using the steps outlined above.
2. Select the first network in the list.
3. Hold down the Shift key and click the last network to select all networks at once. Alternatively, hold Command (⌘) and click individual networks to select multiple entries.
4. Click the minus (–) button or choose Forget This Network to remove all selected networks.
5. Confirm the removal and apply your changes.

Keep in mind that removing all networks means you will need to re-enter passwords for any Wi-Fi networks you want to use again, including your home and work networks.

How to Forget a Wi-Fi Network Using Terminal

Advanced users and IT administrators may prefer to use Terminal to remove a Wi-Fi network. This method is fast, scriptable, and useful when the graphical interface is unresponsive or when managing multiple Macs remotely.

Step-by-Step Instructions

1. Open Terminal: Go to Applications > Utilities > Terminal, or use Spotlight (Command + Space) and type Terminal.
2. Identify your Wi-Fi interface: Run the following command to list network hardware:

   networksetup -listallhardwareports

   Look for the device name next to “Wi-Fi” (usually en0 on most Macs).

3. View saved preferred networks: To see the list of saved networks, run:

   networksetup -listpreferredwirelessnetworks en0

   Replace en0 with your actual Wi-Fi interface if it differs.

4. Remove a specific network: To forget a network, use:

   networksetup -removepreferredwirelessnetwork en0 "NetworkName"

   Replace NetworkName with the exact name of the Wi-Fi network (keep the quotation marks if the name contains spaces).

5. Verify the removal: Run the list command again to confirm the network no longer appears in your preferred networks.

You may be prompted to enter your administrator password. Terminal commands take effect immediately, making this one of the quickest ways to handle How to Forget Wifi Network Mac? when you are comfortable with the command line.

Troubleshooting: When Your Mac Won’t Forget a Wi-Fi Network

Sometimes a network refuses to stay forgotten. If you remove a network and it keeps coming back, one of the following issues may be the cause.

The Network Keeps Reappearing

If a deleted network shows up again in your Known Networks or Preferred Networks list, restart your Mac after removing it. A restart clears temporary caches and ensures the change is fully applied. Also, double-check that you clicked Apply (on older macOS versions) after removing the network.

iCloud Keychain Is Syncing the Network Back

iCloud Keychain syncs Wi-Fi passwords across your Apple devices. If another device still has the network saved, it may sync back to your Mac. To prevent this:

• Forget the network on all your Apple devices signed in with the same Apple ID.
• Alternatively, temporarily turn off iCloud Keychain on your Mac by going to System Settings > [Your Name] > iCloud > Passwords and Keychain (or the equivalent location in System Preferences), then forget the network and turn Keychain back on.

The Network Is Managed by a Configuration Profile

If your Mac is managed by an employer, school, or IT department, a configuration profile may automatically reinstall certain Wi-Fi networks. In this case:

• Go to System Settings > Privacy & Security > Profiles (or System Preferences > Profiles on older versions) to see if any profiles are installed.
• If a profile is managing the network, you may not be able to remove it permanently without removing the profile or contacting your IT administrator.
• Do not remove profiles you do not recognize or that are required for work or school access without first checking with your administrator.

How to Rejoin a Wi-Fi Network After Forgetting It

Forgetting a network is reversible. If you need to connect again, the process is simple:

1. Click the Wi-Fi icon in the menu bar.
2. Select the network you want to join from the list of available networks.
3. Enter the network password when prompted.
4. Optionally, check the box to Remember this network or allow auto-join so your Mac connects automatically in the future.

If the network does not appear in the list, it may be hidden. In that case, choose Join Other Network (or Other) from the Wi-Fi menu and manually enter the network name (SSID), security type, and password.

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

Knowing How to Forget Wifi Network Mac? is just one part of keeping your wireless connections secure and reliable. These tips will help you manage your Wi-Fi networks more effectively:

• Regularly audit your saved networks: Every few months, review your Known Networks or Preferred Networks list and remove entries you no longer use.
• Prioritize your networks: On macOS Monterey and earlier, you can drag networks up or down in the Preferred Networks list to set connection priority. Place your most trusted networks (like home and work) at the top.
• Disable auto-join for public networks: For cafes, airports, and hotels, turn off auto-join so your Mac does not connect automatically to potentially insecure networks. On modern macOS, you can adjust this in the network’s details within Known Networks.
• Use a password manager: Store Wi-Fi passwords in a secure password manager so you can easily reconnect after forgetting a network.
• Be cautious with iCloud Keychain: iCloud Keychain is convenient, but remember that changes to saved networks may sync across all your devices. Review your Keychain settings if you want more control.
• Update macOS regularly: Apple frequently improves network management and security. Keeping your Mac up to date ensures you have the latest fixes and features.
• Restart Wi-Fi when troubleshooting: Before forgetting a network, try turning Wi-Fi off and on, or restarting your Mac. Sometimes a simple reset resolves the issue without removing saved credentials.
• Check for configuration profiles: If you use a work or school Mac, be aware that managed profiles may override your network settings. Coordinate with your IT department before making changes.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete it from my router?

No. Forgetting a network only removes the saved network information from your Mac. It does not affect the router, the network itself, or any other devices connected to it.

Will forgetting a Wi-Fi network on my Mac remove it from my iPhone or iPad?

It can, if iCloud Keychain is enabled on all your devices with the same Apple ID. iCloud Keychain syncs Wi-Fi passwords across devices, so removing a network on one device may remove it from others. To avoid this, turn off iCloud Keychain temporarily or forget the network on each device individually.

Why can’t I see the “Forget This Network” option?

The option may be hidden or labeled differently depending on your macOS version. On macOS Ventura and later, look in System Settings > Wi-Fi > Known Networks and click the More button next to the network. On older versions, go to System Preferences > Network > Wi-Fi > Advanced. If the network is managed by a configuration profile, you may not have permission to remove it.

How do I forget a Wi-Fi network I am not currently connected to?

You do not need to be connected to a network to forget it. Simply open your Known Networks or Preferred Networks list, find the network in the saved list, and remove it using the steps for your macOS version.

Is it safe to remove all saved Wi-Fi networks?

Yes, it is safe, but it is inconvenient. You will need to re-enter the passwords for every network you want to use again. Make sure you know your important Wi-Fi passwords before clearing the entire list.

What is the difference between turning Wi-Fi off and forgetting a network?

Turning Wi-Fi off disables your Mac’s wireless connection entirely but keeps all saved networks intact. Forgetting a network deletes that specific network’s saved credentials and settings while leaving Wi-Fi turned on and other saved networks unaffected.

Can I forget a Wi-Fi network using Terminal without administrator privileges?

In most cases, modifying preferred wireless networks with the networksetup command requires administrator privileges. You may be prompted to authenticate, or you may need to prefix the command with sudo and enter your administrator password.

Conclusion

Understanding How to Forget Wifi Network Mac? gives you greater control over your Mac’s wireless connections, helps resolve stubborn connectivity issues, and improves your privacy when using public networks. Whether you use the streamlined Known Networks interface in macOS Ventura and later, the classic Preferred Networks list in older versions, or the power of Terminal, removing a saved Wi-Fi network takes only a few moments.

By combining the step-by-step methods in this guide with smart habits—like auditing saved networks, managing auto-join settings, and keeping an eye on iCloud Keychain—you can keep your Mac’s Wi-Fi experience fast, secure, and hassle-free. The next time your Mac insists on joining the wrong network, you will know exactly what to do.
