Forgetting or Removing a WiFi Profile from a Mac

Your device saves a profile for each Wi-Fi network you join so it can reconnect automatically in the future. Occasionally, changes to the network or its security settings can cause an older profile to interfere with your connection. Deleting outdated or unused Wi-Fi profiles can help ensure a smooth connection experience.
