Annoyingly, AirDrop works directly over wifi, meaning that you can't use it to transfer files between an iPhone (connected to router Foo via wifi) and a Mac that's 1. Ethernet-wired to the same router Foo, and 2. has no wifi support.

I'm not sure if (Intel-era) Macs without wireless cards/chipsets exist outside of Hackintoshes, but they're pretty common as Hackintoshes.

AirDrop is fantastic, I wish every platform had it.

For us AirDrop only works sometimes. It cannot be trusted to work.

We have two ipads, two iphones, two Macs. Some new, some old. In general AirDrop only works between some devices, depending on device ages and (I guess ;-) the moon in conjugation with Apple's stock index.

If it works, its only after waiting a while, switching BT off and on (maybe repeat that), meanwhile doing some praying...

or you can use ShareDrop[1]. No need to download any native app.

yopp - when you reinvent the wheel because you don't have airdrop
