How to Connect WiFi to an iMac
By Steve Gregory
Although an iMac is a desktop computer, it can still connect to a Wi-Fi network because it has a built-in wireless adapter. As long as your iMac computer is within range of your Wi-Fi network signal, you can access your company's network resources and the Internet without the hassle of running cables. Connect the iMac to the Wi-Fi network using the wireless utility in OS X. You need the password for the network from the network administrator to complete the connection process.
Open the Apple menu and choose "System Preferences" from the drop-down list.
Click "Network" in the Internet and Wireless section to open the Network window.
Click "Wi-Fi" from the list of connection items in the box.
Click the "Network Name" drop-down box and select the name of the wireless network.
Enter the password for the network and click the "Join" button to connect the iMac to the network. The Status field will display "Connected" after the connection is established.
Turn on your iMac's wireless adapter before you connect to a Wi-Fi network. Click the Wi-Fi icon in the menu bar on the desktop and then click "Turn Wi-Fi On" from the drop-down list.
