I've also never had Airdrop work properly. Back To My Mac is finicky as well, and there's insufficient transparency in how it works for me to figure out exactly what I'm doing wrong.
Could you describe where things went wrong with Airdrop? I haven't found much use of it either, but it did work between mine and two of my classmates computers without any issues.
Computers just don't show up, despite, as far as I can tell, being properly configured for it. It's probably a network settings thing (as I believe it is with BTMM). I've only used it on my local LAN though.
AirDrop is a Mac-to-Mac connection, and works only between specific and supported WiFi-connected Mac systems. The connection is directly between Mac systems, and not via WiFi router nor AP.
Older WiFi devices don't support the necessary transfer mode.
I think it's only meant to be wireless. Also, it requires both computers to have the "Airdrop"-section in Finder open at the same time. And finally, it only works with Macs manufactured from some point in 2009, due to the specific hardware it requires. Would any of these possibly be the cause of the issue?
