Special Considerations

Supervised Devices and Wi-Fi Networks

In certain cases, such as with supervised devices, the option to forget a Wi-Fi network may not be available. This limitation is often in place to maintain network security and management policies. If you encounter this situation, consult with your device administrator for further assistance.

Networks Never Joined

It’s important to note that your MacBook can only forget networks that it has previously joined. This means that if you’re attempting to remove a network your device has never connected to, the option to forget this network will not be present. This limitation underscores the importance of managing your Wi-Fi connections actively for optimal device performance and security.

Alternative Solutions

Disabling Auto-Join

An effective alternative to forgetting a Wi-Fi network is to disable the auto-join feature. This option prevents your MacBook from automatically connecting to a network without removing it from your list of saved networks. To disable auto-join:

  • Navigate to System Settings and select Wi-Fi.
  • Click on the Info button next to the network you wish to modify.
  • Uncheck the Auto-Join option.

Is it possible to forget all Wi-Fi networks at once on a MacBook?

Directly, macOS does not offer an option to forget all Wi-Fi networks at once through the GUI. You would need to remove each saved network individually or use Terminal commands for a bulk action.
