Check the WiFi icon in your menu bar to confirm that it is activated. If it’s not lit up, click on the icon and select “Turn WiFi On.” If WiFi is on and networks are still missing, restarting your router may help, as the issue could stem from the network itself.
Additionally, if the problem persists, try resetting your Mac’s network settings entirely. You can do this by opening the “Terminal” application and typing in specific commands to flush the DNS cache or reset network configurations. If necessary, consult Apple support for further troubleshooting, as hardware issues may also hinder your Mac’s ability to detect wireless networks.
