How to Forget Network in Mac: Simple Steps

Managing your Wi-Fi connections on a Mac is crucial for maintaining a seamless and secure digital experience. Over time, your Mac may store multiple Wi-Fi networks, some of which may no longer be relevant or could be causing connectivity issues. Removing old or problematic networks can significantly improve your Mac’s connectivity and security posture.

Forgetting a Wi-Fi network on your Mac is a straightforward process that can be accomplished through the System Settings or System Preferences, depending on your macOS version. For detailed steps, you can refer to Apple’s official support page on managing Wi-Fi networks. By doing so, you’ll be able to streamline your network list and enhance your overall Mac experience.

Understanding how to manage your saved networks is an essential skill for Mac users who want to optimize their device’s performance and security. This guide will walk you through the simple steps to forget Wi-Fi networks on your Mac, ensuring you have a clean and efficient network list.

Why You Might Need to Forget a Wi-Fi Network

Your Mac’s ability to remember Wi-Fi networks can sometimes cause more problems than it solves. For instance, when you visit a coffee shop or airport, your Mac might automatically connect to a public Wi-Fi network you’ve used before. However, this convenience can lead to connectivity issues or security risks if the network has changed or is no longer secure.

Troubleshooting Connection Issues

Forgetting a Wi-Fi network can help resolve connectivity problems. If a network’s configuration has changed, such as its password, deleting the old network allows you to reconnect with the new settings. This is particularly useful when you’re experiencing connection issues due to corrupted network settings. By forgetting the network, you can establish a fresh connection with proper configurations.

Enhancing Security by Removing Old Networks

Removing outdated networks, especially those with weaker security protocols like WEP, significantly reduces potential security vulnerabilities on your device. Your Mac stores detailed information about each Wi-Fi network it connects to, including passwords and security protocols, which could be accessed by malicious actors if not properly managed.

Preventing Automatic Connections to Unwanted Networks

Public networks from hotels, cafes, and airports should be regularly removed from your saved networks list to prevent automatic reconnection when in range. Forgetting these networks helps maintain your device’s security and prevents unwanted connections. According to a guide on HelloTech, managing your Wi-Fi networks is crucial for maintaining your Mac’s security.

How to Forget Network in Mac Using System Settings

Forgetting a Wi-Fi network on your Mac is a straightforward process that can be completed through System Settings. This process varies slightly depending on your macOS version.

For macOS Ventura and Later

To forget the currently connected network in macOS Ventura or later, navigate to System Settings, click on Wi-Fi, and then click Details next to your current network. Select Forget This Network and confirm by clicking Remove.

Forgetting the Currently Connected Network

Choose Apple menu > System Settings, click Wi-Fi, and click Details next to the network you’re using.

Removing Previously Joined Networks

Scroll down, click Advanced, and remove the desired network from the list.

For Older macOS Versions

For older macOS versions, the process involves System Preferences. Navigate to System Preferences > Network, select Wi-Fi, and click Advanced. Here, you can remove previously joined networks.

Using System Preferences

Go to System Preferences > Network, and select Wi-Fi.

Navigating the Advanced Wi-Fi Settings

Click Advanced and remove the network using the minus button.

macOS Version	Steps to Forget Network
macOS Ventura and Later	System Settings > Wi-Fi > Details > Forget This Network
Older macOS Versions	System Preferences > Network > Wi-Fi > Advanced > Remove Network

Alternative Methods to Remove Wi-Fi Networks

There are alternative strategies for forgetting Wi-Fi networks on a Mac that don’t involve navigating through system settings. These methods provide users with more flexibility and efficiency in managing their network connections.

Using the Wi-Fi Menu in the Menu Bar

The Wi-Fi menu in the menu bar offers a quick and convenient way to access network settings. By clicking the Wi-Fi icon in the top-right corner of your screen, you can select “Open Network Preferences” to directly access the network management interface. This method is particularly useful when you need to quickly forget the currently connected network.

Terminal Commands for Power Users

For advanced users, Terminal provides powerful command-line options to forget Wi-Fi networks with greater efficiency and precision. To remove a network, open the Terminal application and type the command networksetup -removepreferredwirelessnetwork en0 NETWORK_NAME, replacing ‘NETWORK_NAME’ with the exact name of the Wi-Fi network to forget.

Method	Description
Wi-Fi Menu	Quick access to network settings via the menu bar
Terminal Command	Precise removal of Wi-Fi networks using command-line interface

Managing Multiple Networks and Special Cases

Effectively managing multiple Wi-Fi networks on your Mac involves understanding various settings and options. This knowledge is crucial for maintaining organized network settings, especially in environments with numerous networks.

Batch Removal of Several Networks

For users with many saved networks, removing them in batches can be more efficient than doing so individually. Using Terminal commands, you can list all saved networks with “networksetup -listpreferredwirelessnetworks en0” and then remove multiple networks systematically. However, caution is advised to avoid removing essential networks.

Command	Description
networksetup -listpreferredwirelessnetworks en0	Lists all saved Wi-Fi networks
networksetup -removepreferredwirelessnetwork en0 <network_name>	Removes a specific Wi-Fi network

Handling Supervised Devices and Managed Networks

Supervised devices, often managed by institutions, may have restrictions on forgetting certain networks. Managed networks, typically used in organizational settings, require administrator privileges to modify. Understanding these limitations is key to managing networks on supervised devices.

What Happens When You Forget a Network

Forgetting a network on your Mac removes all stored information about that network, including its password and security type. Although your Mac will still detect the network, it will be treated as a new network upon reconnection. Alternatively, you can disable “Automatically join this network” to prevent automatic reconnections without forgetting the network.

Conclusion: Keeping Your Mac’s Network Connections Organized

Keeping your Mac’s network connections organized is essential for optimal performance and security. By regularly managing your saved Wi-Fi networks, you can improve both the performance and security of your device.

Effective network management involves removing outdated connections to prevent your Mac from attempting to connect to low-quality or potentially insecure networks. It’s also crucial to note down important network passwords before removing them, as forgetting a network removes its password from your keychain.

By implementing these network management practices, you’ll enjoy more reliable connections and better overall Wi-Fi performance on your Mac. For ongoing network issues, consider exploring deeper troubleshooting options through Apple Support resources.
