Remove or forget a wireless network on a macOS computer / Wireless Network

Problem

• How do I remove or forget a wireless network from the list of networks on my macOS computer?

Cause

• If you experience an issue when connecting to a wireless network on a computer running OS 13 or greater, try forgetting the wireless network. This enables the computer to reset settings — usernames, passwords, or configurations — allowing the device to reconnect to the network 

Resolution 

To forget or delete a wireless network in OS 13 or greater, follow this procedure:

1. Select the Wi-Fi symbol in the menu bar
2. Click Wi-Fi Settings... from the drop-down menu
3. In the Network window, select Wi-Fi in the left panel
4. Click the Advanced... button at the bottom
5. Choose the wireless network you want to delete and click the 3 dots in a circle to the right
6. Select Remove from List
7. Click Forget
8. If prompted, click the Apply button to confirm changes
9. You may need to uninstall the MU-WIRELESS or MiamiOH-Secure profiles if you have it installed. This can be accomplished by going to System Preferences > Profiles. Remove anything that references MU-WIRELESS or MiamiOH-Secure by selecting it and clicking the minus button

Notes

• If these instructions are being used to forget and re-add the MiamiOH-Secure network, follow these KB instructions to connecting a macOS computer to MiamiOH-Secure
• If you can see the wireless networks, but are still unable to connect to the Miami network, contact IT Help by phone at 513-529-7900 or by live chat at MiamiOH.edu/ITChat. Provide the following information:
