As we all know, switching to a different operating system can be a tough experience. If you just got your new Mac, and don’t know how to connect to the internet on it, this article will be very helpful to you.
Start out at your desktop:
Look at the top, then look for the icon that looks like a wireless bar signal
Click it, and choose the network you want to connect to. If none are listed, make sure AirPort is on
If the network has a wifi block, enter in the password required to connect. If you are trying to connect to your home network, and you have internet access on another computer, go to your default gateway (router address) and you can view your security password there. If you have a security block, and you don’t have internet access on any other machine, you can do a hard reset on your router to remove the security block.
