Are you tired of your MacBook constantly connecting to a Wi-Fi network that’s no longer needed or has become a nuisance? Do you want to remove the network from your device’s memory to prevent automatic connections or improve your online security? Look no further! In this article, we’ll guide you through the simple steps to forget a Wi-Fi network on your MacBook.
Why Forget a Wi-Fi Network?
Before we dive into the process, let’s explore the reasons why you might want to forget a Wi-Fi network on your MacBook.
Security Concerns: If you’ve connected to a public Wi-Fi network or a network that’s no longer in use, it’s essential to remove it to prevent potential security risks. Hackers can exploit your connection to gain access to your device and sensitive information.
Automatic Connections: When your MacBook remembers a Wi-Fi network, it will automatically connect to it whenever it’s in range. This can be frustrating if you’re trying to connect to a different network or prefer to use a wired connection.
Network Congestion: Forgetting an unnecessary Wi-Fi network can help reduce network congestion and improve your overall internet experience.

Why do I need to forget a Wi-Fi network on my MacBook?
Forgetting a Wi-Fi network on your MacBook is essential when you no longer want to connect to that network automatically. Perhaps you’ve changed your router or moved to a new location, and you don’t want your MacBook to try to connect to a network that’s no longer available or relevant. Forgetting the network allows you to remove it from your MacBook’s memory, which means you won’t receive notifications or attempts to connect to that network anymore.
Additionally, forgetting a Wi-Fi network can also help resolve connectivity issues. If you’re experiencing problems with your current network connection, forgetting the network and then reconnecting can often resolve the issue. It’s also a good security practice to forget networks that you no longer use, as it reduces the risk of your MacBook automatically connecting to an unsecured or malicious network.
How do I forget a Wi-Fi network on my MacBook?
To forget a Wi-Fi network on your MacBook, you’ll need to access the Wi-Fi settings. Click on the Apple menu and select “System Preferences,” then click on “Wi-Fi” or “Network.” From there, select the network you want to forget from the list of available networks, and click the “-” button at the bottom of the list. You’ll be prompted to confirm that you want to remove the network, and once you click “Remove,” the network will be forgotten.
Make sure you’re connected to another network or have a cellular connection before forgetting the network, as you’ll need internet access to complete the process. Additionally, if you’re using a MacBook with macOS High Sierra or later, you may need to click on “Advanced” in the Wi-Fi settings and then click on “Wi-Fi” to access the list of available networks.
Will forgetting a Wi-Fi network delete my saved passwords?
No, forgetting a Wi-Fi network on your MacBook will not delete your saved passwords. Your passwords are stored in the Keychain app, which is separate from the Wi-Fi settings. When you forget a Wi-Fi network, only the network settings are removed, not any associated passwords.
However, if you’re using a MacBook with macOS High Sierra or later, you may need to delete the password separately. To do this, go to “Keychain Access” and search for the network name. Delete the password entry, and then forget the network as described above.
Can I forget a Wi-Fi network on my MacBook using the command line?
Yes, you can use the command line to forget a Wi-Fi network on your MacBook. Open the Terminal app and type the command “sudo /usr/sbin/networksetup -removepreferredwirelessnetwork
Note that this method requires administrator privileges, and you’ll need to enter your password to execute the command. Also, be careful when using the command line, as incorrectly entered commands can cause system issues.
Will forgetting a Wi-Fi network affect my other devices?
No, forgetting a Wi-Fi network on your MacBook will not affect your other devices. The network settings are specific to each device, so forgetting a network on your MacBook will only remove the network from your MacBook’s memory.
If you want to remove the network from your other devices as well, you’ll need to follow the same process on each device individually. This is because each device has its own network settings and preferences.
Can I forget a Wi-Fi network on my MacBook using a third-party app?
Yes, there are third-party apps available that allow you to forget a Wi-Fi network on your MacBook. One popular app is WiFi Explorer, which provides advanced Wi-Fi network management features, including the ability to forget networks.
Keep in mind that using a third-party app may require additional permissions and access to your system, so be sure to research the app and its developer before installing.
Is it safe to forget a Wi-Fi network on my MacBook?
Yes, forgetting a Wi-Fi network on your MacBook is a safe process. It does not pose any risks to your system or data. However, it’s essential to ensure you’re connected to another network or have a cellular connection before forgetting the network, as you’ll need internet access to complete the process.
Additionally, if you’re using a MacBook with macOS High Sierra or later, be cautious when deleting password entries in Keychain Access, as incorrectly deleting entries can cause issues with other apps and services.
