Snow Leopard (OS 10.6)/Leopard (OS 10.5) WPA2 Configuration


The following set-up instructions were produced using a Apple Macintosh laptop running Snow Leopard (OS 6); the steps are the same for Leopard (OS 5).

Note: Older operating systems may not support WPA2. Your best bet is to use either the Snow Leopard (OS 6) or the Leopard (OS 5) operating system.

  • Before you do anything we recommend you run Software Update to update to the latest version of Leopard or Snow Leopard.

    Apple menu -> System Preferences -> Software Update
