Why can I transfer files from my iMac to my Macpro laptop using Air Drop but not the other way?

I work with an iMac and a MacBook Pro on OSX and have found that I can transfer files from my I

Mac to my notebook using Air Drop without any trouble. However, when I try to transfer the other way from notebook to iMac, my iMac refuses delivery. Why am I doing wrong? I'm using Mac OS X 10.7.5

iMac, Mac OS X (10.7.5), Air Drop

OS X (Lion/Mountain Lion)- Can I use AirDrop with my computer?

Enable AirDrop on Macs without supported wireless hardware


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.
