mac address
The mac address on my wife's MacBook pro disappeared. Now it is no longer able to connect to Wi-Fi.
I've done all of the suggested troubleshooting as of now nothing has worked. Any ideas?
If she has lost the ability to connect to your local network: System Preferences > Network Pick out your network name and supply the password. That will allow connection to your ISP.
