Subject: Pimping airport on older macs to support Air drop in Lion
I recently was disappointed to find that neither my early 2008 imac nor macbookpro support airdrop.
A japanese site reports that the following cards work:
The cards that support AirDrop by default:
Broadcom BCM94322MC, BCM94322HM8L
Atheros AR5BXB112, AR5BXB92, AR5BHB92, AR5B93
(And sounds like Atheros AR5B95 would work if AirPortAtheros40.kext edited to add DevID = 0x002b. Ditto for AR5BXB72 if edited for DevID = 0x0024.)
Cards that do not support AirDrop:
Broadcom BCM94321MC, BCM94312MCG, BCM94312MCAG, BCM94311MCG
I'm in the process of buying a broadcom card off ebay and will attempt to install as soon as it arrives. An install video is available on youtube: Core Duo 15in MacBook Pro Airport Card Replacement
(There's an old illustrated article here on that card swap/upgrade from Feb. 2007. Of course Lion doesn't support Core Duo CPUs.)
If any one else has any input on this topic it would be appreciated.
