If your Mac constantly disconnects from your fast home network to connect to a weak, public hotspot down the street, you can stop this behavior without entirely forgetting the network.
How to Stop Automatic Wi-Fi Connections
- Open System Settings on your Mac.
- Click on Wi-Fi in the left sidebar.
- Scroll down and click the Advanced button at the bottom right.
- Find the offending network in the “Known Networks” list.
- Click the circle with three dots next to it and select Auto-Join to toggle it off.
