If you don’t see a Wi-Fi icon in the menu bar, choose Apple menu > System Preferences, click Network, select Wi-Fi in the services list, then select “Show Wi-Fi status in the menu bar.”

Open Network preferences for me

To join a public network, click the Wi-Fi icon in the menu bar, then choose the network you want to join.

If the network you’re joining is protected by a password, you need to enter it before you can join the network.

To join a hidden network, click the Wi-Fi icon then choose Join Other Network.

You need to know the hidden network’s name, security protocol, and password to join it.
