AirDrop between iPhone/Mac Requirements
AirDrop won’t work on all Macs and all iOS devices, so it may not be a feature you can take advantage of. AirDrop is (apparently) supported by the following Mac models:

MacBook Air (2012 or newer)
MacBook Pro (2012 or newer)
iMac (2012 or newer)
Mac mini (2012 or newer)
Mac Pro (Late 2013)
We say ‘apparently’ because it took us a very long time to get AirDrop to work between our 2012 MacBook Air and an iPhone 5s - and then when we did it was entirely unsustainable.
