Does my Mac support 802.11n?
These Mac computers support 802.11n in the new AirPort Extreme Base Station using the included enabler software:
iMac with Intel Core 2 Duo (except 17-inch, 1.83GHz iMac)
MacBook with Intel Core 2 Duo
MacBook Pro with Intel Core 2 Duo
Mac Pro with AirPort Extreme card option
Bizaarly, it seems I must buy the new Extreme base station to get the software to unlock the capabilities of my laptop. But the Airport Expresses on the network will still slow it down to “g” speeds anyway, so I think I’ll wait until there’s an AirTunes supporting “n” product from Apple, too.
