Many Mac computers with an Intel Core 2 Duo and all Mac Pro computers with AirPort Extreme can be enabled to access 802.11n-based wireless networks. If you purchased one of these Macs, you can use the AirPort Extreme 802.11n Enabler software to activate this advanced wireless capability.

Important note: The Enabler is included free with the new AirPort Extreme Base Station with 802.11n. If you purchase a new AirPort Extreme Base Station, you do not need to purchase the Enabler separately.

These Macs have the 802.11n hardware built-in:
