What Does “Forget Wifi” Mean on a Mac?

When your Mac connects to a Wi-Fi network for the first time, it saves the network name (SSID) and password in a secure database. The next time that network is in range, your Mac automatically reconnects without asking for credentials. This convenience is great for home and office networks, but it can become a problem when you no longer want that automatic connection.

Choosing to “forget” a network tells macOS to delete that saved entry. After forgetting, your Mac will no longer auto-connect to that SSID, and it will prompt you for a password if you try to join manually. Importantly, forgetting a network does not delete the password from your iCloud Keychain if it is synced across devices, which is why some networks seem to “come back” after being removed.

Why You Might Want to Forget a Wifi Network

There are many legitimate reasons to remove a saved network from your Mac. Understanding these scenarios helps you decide whether forgetting is the right action.

  • Security: If you connected to a public hotspot at a coffee shop or airport, leaving it saved means your Mac may auto-connect to a rogue network with the same name later.
  • Network changes: Your router was replaced or renamed, and the old SSID no longer works.
  • Performance: Your Mac keeps jumping to a weaker saved network instead of staying on the strongest one.
  • Privacy: Shared or work Macs may have networks saved by previous users that you want removed.
  • Troubleshooting: Corrupted network profiles can cause connection failures, and forgetting then rejoining often fixes them.

How to Forget Wifi in Mac? (macOS Ventura and Later)

Apple redesigned System Settings starting with macOS Ventura, moving away from the older System Preferences layout. If your Mac runs Ventura, Sonoma, Sequoia, or newer, follow these steps.

Step-by-Step Instructions

  1. Click the Apple menu in the top-left corner and select System Settings.
  2. In the sidebar, click Wi-Fi.
  3. Scroll down to the section labeled Known Networks (or click Advanced on some versions).
  4. Find the network you want to remove.
  5. Click the three dots (…) or the minus (-) button next to the network name.
  6. Select Forget This Network (or Remove).
  7. Confirm by clicking Remove in the dialog box.

After completing these steps, the network disappears from your Known Networks list. If you want to reconnect later, you will need to select it from the Wi-Fi menu and enter the password again.

How to Forget Wifi in Mac on Older macOS Versions

If you are running macOS Monterey, Big Sur, Catalina, Mojave, or earlier, the interface is different. Here is how to forget a network on those systems.

macOS Monterey and Big Sur

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

macOS Catalina and Earlier

  1. Open System Preferences and choose Network.
  2. Select Wi-Fi and click Advanced.
  3. In the Wi-Fi tab, highlight the desired network.
  4. Click the minus (-) button.
  5. Click OK and then Apply to save changes.

These older methods are still widely used because many Macs cannot upgrade to the latest macOS. The core concept remains the same: open Network settings, find the preferred networks list, and remove the entry.

Comparison of Methods Across macOS Versions

The table below summarizes where to find the forget option depending on your macOS version.

macOS Version Settings Location Button to Remove Notes
Ventura, Sonoma, Sequoia System Settings > Wi-Fi > Known Networks Three dots or minus Redesigned interface
Monterey, Big Sur System Preferences > Network > Advanced Minus button Classic layout
Catalina, Mojave, High Sierra System Preferences > Network > Advanced Minus button Same as above
Terminal (all versions) Command line networksetup command Best for scripting

How to Forget Wifi in Mac from the Menu Bar

Sometimes you do not want to open System Settings at all. You can manage known networks directly from the Wi-Fi icon in the menu bar, though the exact capability varies.

  1. Click the Wi-Fi icon in the menu bar.
  2. Select Wi-Fi Settings (or Network Preferences on older systems).
  3. Follow the same steps as above to remove the network.

On very recent macOS versions, you can also click the network name while holding Option to see additional details, but removing still routes you to Settings. This method is convenient when you are already connected and want to quickly switch or forget a network without navigating through multiple menus.

How to Forget Wifi in Mac Using Terminal

Power users and IT administrators often prefer the command line because it is fast and scriptable. macOS includes the networksetup tool for managing network interfaces.

Terminal Commands

  1. Open Terminal from Applications > Utilities.
  2. List your Wi-Fi interfaces by running: networksetup -listallhardwareports
  3. Identify your Wi-Fi device, usually en0 or Wi-Fi.
  4. View saved networks with: networksetup -listpreferredwirelessnetworks en0
  5. Remove a specific network with: networksetup -removepreferredwirelessnetwork en0 "NetworkName"

Replace en0 with your actual interface name and NetworkName with the exact SSID, including spaces if present. Wrap the SSID in quotes. This method is especially useful when managing multiple Macs or when the graphical interface is unresponsive.

Important: Terminal commands require administrator privileges for some operations. If you see a permission error, prefix the command with sudo and enter your password.

How to Forget Wifi in Mac for All Users

On a Mac with multiple user accounts, Wi-Fi networks saved by one user may not appear for another. However, if the network was saved at the system level or synced via iCloud, it can persist across accounts.

To ensure a network is forgotten for all users:

  • Log in to each user account and remove the network individually using the steps above.
  • Check System Settings > Wi-Fi > Advanced (or Network preferences) for system-level entries.
  • Use Terminal with sudo to remove system-wide preferred networks.
  • Disable iCloud Keychain syncing temporarily if the password keeps returning.

In managed environments, administrators can also use configuration profiles or MDM tools to enforce network removal across all accounts.

How to Remove Wifi Passwords from Keychain

Even after forgetting a network, its password may remain in Keychain Access. This is why the network can sometimes reappear or auto-connect if iCloud Keychain re-syncs it.

Removing Passwords from Keychain

  1. Open Keychain Access from Applications > Utilities.
  2. In the search box, type the name of the Wi-Fi network.
  3. Look for entries of type AirPort network password or Internet password.
  4. Select the entry and press Delete.
  5. Confirm deletion.

If you use iCloud Keychain, the deletion may sync to your other Apple devices. This is usually desirable, but be aware that removing a password from Keychain means you will need to re-enter it on all devices if you reconnect later.

Troubleshooting: Wifi Network Keeps Reappearing

One of the most common frustrations is removing a network only to see it return. Here are the likely causes and fixes.

iCloud Keychain Sync

If iCloud Keychain is enabled, the password can be restored from another device. To prevent this, turn off iCloud Keychain temporarily, remove the network, then re-enable it.

Configuration Profiles

On work or school Macs, an MDM profile may push network settings back. Contact your administrator or check System Settings > General > VPN & Device Management for installed profiles.

Corrupted Preference Files

Sometimes the network plist file becomes corrupted. You can reset network settings by removing preference files in /Library/Preferences/SystemConfiguration/, but this should be done carefully and only as a last resort.

Auto-Join Settings

Even if a network is saved, you can disable auto-join without fully forgetting it. In Wi-Fi settings, click the info (i) button next to the network and toggle off Auto-Join. This keeps the password saved but stops automatic connections.

Tips and Best Practices

  • Forget public networks immediately after use to reduce security risks.
  • Use unique, strong passwords for your home network so that forgetting and rejoining is not a frequent necessity.
  • Keep macOS updated to ensure the Settings interface matches current documentation.
  • Document network names before forgetting them if you might need to reconnect later.
  • Use Terminal for bulk removal when cleaning up many saved networks at once.
  • Review Keychain periodically to remove stale passwords.
  • Disable auto-join instead of forgetting if you want to keep the password for occasional manual use.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete the password?

It removes the password from your Mac’s saved network list, but the password may remain in Keychain Access. If iCloud Keychain is enabled, it can also persist on other devices.

Can I forget a network I am currently connected to?

Yes, but your Mac will disconnect immediately. Make sure you have an alternative connection or the password handy before doing so.

Why does my Mac keep connecting to a network I forgot?

This usually happens because of iCloud Keychain syncing, a configuration profile, or a corrupted preference file. Check Keychain Access and iCloud settings.

Is there a way to forget all Wi-Fi networks at once?

There is no single “forget all” button in the GUI, but you can use Terminal to loop through and remove multiple networks, or reset network settings entirely.

How to Forget Wifi in Mac if I do not know the password?

You do not need the password to forget a network. Forgetting only removes the saved entry; it does not require authentication.

Will forgetting a network affect other devices?

Only if iCloud Keychain is syncing passwords. Otherwise, the change is local to that Mac.

Conclusion

Knowing How to Forget Wifi in Mac? is an essential skill for anyone who uses a Mac regularly. Whether you are troubleshooting connection issues, improving security, or simply cleaning up old networks, the process is straightforward once you know where to look. Modern macOS versions place the option under System Settings > Wi-Fi, while older versions use System Preferences > Network > Advanced. For advanced users, Terminal provides a fast, scriptable alternative, and Keychain Access ensures passwords are fully removed.

By following the steps and best practices in this guide, you can keep your Mac’s wireless connections organized, secure, and free from unwanted auto-connections. If a network keeps reappearing, check iCloud Keychain, configuration profiles, and preference files before assuming the removal failed. With these tools and techniques, you are fully equipped to manage Wi-Fi networks on any Mac.
