How To Forget Wifi Network On Mac

In my digital journey, there’s been the occasional need to ‘clean house’ with my Wi-Fi connections, particularly on my Mac. Removing old networks can help with troubleshooting issues, streamlining connections, and enhancing security. In this article, I’ll share the methods I’ve used to forget Wi-Fi networks on a Mac.


Common Scenarios:

Effortless Network Clean-Up 🧹

  • Cleaning up your list of remembered Wi-Fi networks can improve connection times and reduce confusion.
  • When dealing with Wi-Fi names (SSIDs) that are similar, it helps to clear out old or unused ones.

Security Hygiene 🛡

  • Forgetting old networks is integral to good security hygiene, especially networks from hotels, airports, or coffee shops that you no longer visit.
  • This process can help ensure your Mac doesn’t automatically connect to networks with weaker security.

Connectivity Troubleshooting 🛠

  • Forgetting a network and reconnecting can resolve connectivity issues.
  • If a Wi-Fi network’s configuration has changed (like its password), deleting the old network from your device can allow you to reconnect with the new settings.

Step-by-Step Guide. How To Forget Wifi Network On Mac:

Method 1: Through System Preferences 🎛

  • Open System Preferences and select ‘Network’.
  • Choose ‘Wi-Fi’ from the list on the left and click on the ‘Advanced’ button.
  • Find the network you want to forget, select it, and then click on the ‘-‘ button to remove it.
  • Click ‘OK’ to confirm and ‘Apply’ to save the changes.

Note: You’ll need administrative privileges to make these changes.

Conclusion: This method is very straightforward and user-friendly, especially for less tech-savvy users.

Method 2: Using Keychain Access 🗝

  • Open the Keychain Access app found in the ‘Utilities’ folder of your ‘Applications’.
  • Search for the Wi-Fi network name (SSID) in the top right search bar.
  • Select the relevant network and right-click to choose ‘Delete’.
  • Enter your Mac’s password when prompted and confirm the deletion.

Note: Removing items from Keychain Access is permanent, so ensure you’re deleting the right entry.

Conclusion: This is a more advanced method suited for users who want additional control over their saved networks.

Method 3: Via Terminal for Power Users 🔧

  • Open the Terminal application located in the ‘Utilities’ folder inside ‘Applications’.
  • Type the command networksetup -removepreferredwirelessnetwork en0 NETWORK_NAME replacing ‘NETWORK_NAME’ with the exact name of the Wi-Fi network to forget.
  • Press ‘Enter’ to execute the command.

Note: You may need to replace ‘en0’ with the right interface if it differs on your Mac.

Conclusion: Terminal commands offer a quick and powerful way to make system modifications for experienced users.

Method 4: Batch Removal for Multiple Networks 📶

  • Open Terminal and enter networksetup -listpreferredwirelessnetworks en0 to list all saved networks.
  • Create a command or script to remove all networks listed or several specific ones.
  • For each network you want to forget, run -networksetup -removepreferredwirelessnetwork en0 NETWORK_NAME command.

Note: Be cautious when running batch operations as you might inadvertently remove networks you still use.

Conclusion: This approach is excellent when handling many networks and can save time compared to removing them one by one.

Method 5: For Those With Profiles Installed 🛠

  • Navigate to System Preferences followed by ‘Profiles’.
  • Select the profile that contains the Wi-Fi Network you’d like to forget, and hit the minus (-) button.
  • Confirm the removal of the profile, which will also remove any network settings associated with it.

Note: Profiles are usually installed by organizations to manage Wi-Fi and other settings on devices they supervise.

Conclusion: Understanding whether your network settings are managed by a profile is essential for proper removal.


Precautions and Tips:

Guard Your Wi-Fi Passkeys 🔑

  • Remember that when you forget a network on your Mac, the password is also removed from your keychain.
  • Write down or store the network credentials somewhere secure before removing them if you think you’ll need them again.

Maintain System Integrity 🛡

  • Only make changes to networks you’re familiar with to avoid accidentally disrupting internet connectivity.
  • Regularly check your saved networks to identify and remove any unfamiliar or unused ones.

Handle Profiles with Care 📄

  • If your Mac is part of a corporate or educational institution network, you might require permission before making any changes to profiles.
  • Forgetting a network that is mandated by a profile may result in losing access to other network resources or breaching IT policies.

Enhancing Mac’s Performance

Forgetting Wi-Fi networks on your Mac can have benefits beyond decluttering your connection list. Removing these networks can help streamline your Mac’s performance when connecting to Wi-Fi, as it won’t waste time searching for networks it can’t connect to. It’s also essential for general maintenance and cybersecurity.

Moreover, if you’re frequently on the move, your Mac can accumulate a considerable list of Wi-Fi networks. This can clutter the Wi-Fi dropdown menu and make it difficult to connect to the networks you frequently use. Additionally, older networks could have weak security protocols like WEP, which can pose security risks. For a primer on Wi-Fi security, the website of the non-profit organization, Wi-Fi Alliance, is a good place to start (

Lastly, new users to macOS might find it helpful to review Apple’s official support resources for system preferences and networking features ( They offer a wealth of information to help you understand the nuances of your device better.


Forgetting a Wi-Fi network on your Mac can be a straightforward process, although it requires varying levels of technical knowledge depending on the method you choose. Whether you are a beginner or a tech enthusiast, understanding how to effectively manage your Wi-Fi connections is critical for a seamless internet experience and maintaining the health of your Mac’s networking capabilities. For additional tips and troubleshooting, always check out reliable resources like Apple Support and other established tech forums.
